Full textAbstract:
Lupinus mutabilis Sweet is an Andean protein crop with agro-economic potential. However, it is characterized by low yields and phenotypic plasticity related to environmental conditions when cultivated in different locations in Europe. Current research objective was to evaluate L. mutabilis agro-morphological performance in two locations in Greece and to record its pollinators, since these can contribute to optimization of crop performance. For this purpose, eight Andean lupin accessions, one white and one blue lupin commercial varieties were evaluated for 71 agro-morphological traits in a Randomized Complete Block design with three replications. Combined Analysis over Location presented a significant accession-location interaction for traits of economic interest such as seed crude protein and 100 seed weight. Seed crude protein was higher in L. mutabilis accessions (up to 43.8 g 100 g−1 seed) than white and blue lupins. Andean lupin yielded up to 327 kg ha−1 (LIB214) in Kalamata, while its yield was lower than the white lupin in Athens. Using principal component analysis, three groups of accessions were formed, one by each lupin species and three within Andean lupin accessions. Floral traits such as color and size are related to pollinators diversity and preference. Insect pollinators and floral traits interplay among different lupin species was examined. Pollinators visited L. mutabilis flowers belong to the genera Anthophora, Bombus, Megachile and Xylocopa. The results of the present study, indicate that L.mutabilis has agronomic potential and enhances above ground biodiversity, however breeding for higher yields is required.

Full textAbstract:
Spring frost poses a challenge for all major crops and, in the case of Lupinus mutabilis (Andean lupin) can cause severe damage or even total loss of the crop. Within the LIBBIO project consortium, we conducted a series of experiments in order to develop a suitable protocol for screening lupin germplasm under frost-simulation conditions. Four lupin accessions, one Lupinus albus and three Andean lupins were used in the experiments (L. albus Mihai, L. mutabilis LIB 220, LIB 221, LIB 222). Seedlings at four developmental stages were challenged with five different levels of ‘frost’ stress from low (−2 °C) to high (−10 °C). Notably, young seedling (cotyledons just breaking through the soil surface) showed little evidence of frost damage for temperatures down to −6 °C. At −8 °C, however, damage was evident, suggesting a cold tolerance threshold occurs at this temperature. Interestingly, for later developmental stages, when the first and second leaves were visible, notable differences were observed starting at −6 °C. The results indicate that the plant growth stage is an important parameter when screening for frost tolerance in germplasm. Overall, by identifying Andean lupin genotypes adapted to high abiotic stress factors, farmers will be able to use it as a reference crop with potentially a commercial interest from the food sector, or cosmetics, and biofuel industries.

Full textAbstract:
Anthracnose, caused by Colletotrichum acutatum, is the most destructive fungal disease of Andean lupin (Lupinus mutabilis Sweet) in Ecuador and of other lupin species around the world. Symptoms of necrotic spots occur throughout the main stem, and infection progresses to cause bending of the main stem and lateral branches, resulting in yield loss. Although there is no known anthracnose resistance, this study aims to assess tolerance of Andean lupin and investigate lupin–C. acutatum interactions. Two Andean lupin genotypes, I-450 Andino and I-451 Guaranguito, were inoculated on the meristematic section of the main stem, either by spraying or by pipetting C. acutatum spores on to an artificial wound. Although the two methods gave similar results, spraying is the preferred method because it mimics natural pathogen infection. Plant-pathogen interactions were assessed at five different phenological stages (leaf stages 2–3, 4–5, 6–7, 8–9, and 10–11) with three C. acutatum isolates by using a 0–5 scale to assess disease symptoms. In both genotypes, anthracnose symptoms were greater at early seedling stage (2–3-leaf stage), decreasing significantly in early vegetative phase (6–7-leaf stage) and increasing again when the flower stage began (10–11-leaf stage). However, the tolerance of these two Andean lupin genotypes to anthracnose was not equally expressed at all developmental stages. We recommend, in a breeding program, that screening for anthracnose first occurs at the 6–7-leaf stage (6 weeks old) and again when flowering starts at the 10–11-leaf stage (10 weeks old) so that the overall tolerance can be determined. This method could be used in lupin breeding programs for improving resistance to anthracnose.

Full textAbstract:
Anthracnose, caused by Colletotrichum lupini, is a major limiting factor for lupin production. Tarwi or Andean Lupin (Lupinus mutabilis) is generally regarded as susceptible to anthracnose, but the high protein and oil content of its seeds raise interest in promoting its cultivation in Europe. In this study we evaluated the response to anthracnose of 10 tarwi accessions contrasting in anthocyanin pigmentation, by comparison to white lupin (Lupinus albus), using a contemporary Portuguese fungal isolate. A severity rating scale was optimized, including weighted parameters considering the type of symptoms and organs affected. All tarwi accessions were classified as susceptible, exhibiting sporulating necroses on the main stem from seven days after inoculation. Anthracnose severity was lower on anthocyanin-rich tarwi plants, with accession LM34 standing out as the less susceptible. Accession I82 better combines anthracnose response and yield. In global terms, disease severity was lower on white lupin than on tarwi. Although based on a limited collection, the results of the study show the existence of genetic variability among L. mutabilis towards anthracnose response relatable with anthocyanin pigmentation, providing insights for more detailed and thorough characterization of tarwi resistance to anthracnose.

Full textAbstract:
The Andean lupin (Lupinus mutabilis Sweet) is the only cultivated species of the genus Lupinus originating from South America. Attempts were made to introduce this species to European soil and climatic conditions. The main disadvantages of the Andean lupin include too long and non-uniform maturation of pods in a plant, dropping flowers and pod buds, and a high alkaloid content (up to 5%). The aim of this study was to identify in post-mutagen treated material genotypes with low alkaloid content in seeds, which would be useful for improving L. mutabilis by breeding. The iodine test was annually performed to test the presence of alkaloids in seeds, using Lugol’s solution (I in KI). Based on the turbidity of the test samples, the investigated plants were divided into four groups, labelled as follows: G – individuals with a high content of alkaloids (very bitter), P – individuals with an intermediate content of alkaloids (bitter), PS – individuals with a low alkaloid content (fairly sweet) and S – individuals with a very low alkaloid level (sweet). For further propagation, mainly individuals from the S and PS groups were selected, and by part from the group P, while all bitter forms (G group) were rejected. Thirty chosen lines were examined for the content and composition of alkaloids by gas chromatography. The alkaloid content did not exceed 0.1% in 13 favourable lines, and even two lines had less than 0.05%. The seeds of the studied material contained 7 to 9 different alkaloids. The prevailing alkaloids in the seeds of the Andean lupin were 4-hydroxylupanine and lupanine. Significant progress has been achieved in reducing the content of alkaloids in subsequent generations of the investigated representatives of Lupinus mutabilis from South America.

Full textAbstract:
Lupinus mutabilis is an important source of protein in different Andean countries, and its use in diets, particularly those of less wealthy individuals, has been observed for thousands of years. There is an increasing demand for protein crops suitable for Europe and this species is a potential candidate. Assessment of Lupinus mutabilis genetic material in European conditions started more than 40 years ago, with the characterization of a vast number of accessions from the Andean region. In this review, abiotic and biotic constraints to L. mutabilis cultivation in European soil and climatic conditions are discussed, and cultivation management practices are suggested. The beneficial interaction of L. mutabilis with Bradyrhizobium strains in the soil and various pollinator species is also discussed, and the effect of abiotic stresses on these interactions is highlighted. Prospects of alternative uses of L. mutabilis biomass in Northern Europe and opportunities for breeding strategies are discussed. In conclusion, the different approach to crop modeling for Southern and Northern European climatic conditions is highlighted.

Full textAbstract:
Drought is one of the most important abiotic stresses that causes significant reductions in crop yield, and thushinders the food security of the growing world population. In consequence, it is urgent to select crops able toresist drought, maintain high yield and have a good nutritive content. The purpose of this project was toevaluate the responses of different accessions of Andean lupin to drought stress, and identify if there aresignificant differences in their physiological responses.To identify germplasm for further investigation, thirty accessions of Lupinus mutabilis Sweet. and oneaccession of L. albococcineus Hort. were screened in two sets, A of 15 and B of 16 accessions. From thesesets, four lines were chosen on the basis of extreme values in the measurements, and this set of four wasinvestigated in depth (set C). Water stress consisted of controlled water loss from the soil (at 2% per day).The screening techniques used were: leaf temperature, stomatal conductance, relative water content, waterpotential, ion membrane leakage, and shoot dry weight were measured and transpiration efficiency wascalculated. In addition, carbon isotope discrimination, root length, root dry matter, proline content andsoluble sugar content were included in only set C.Based on the results from set A and set B, accessions PI 457981, PI 457972, and AC 2792 were consideredas being drought resistant and PI 510572 was considered as drought sensitive. However, the results from setC showed that accession PI 510572 is able to adapt its cell membrane to the drought stress so that its ionleakage is less than in the other accessions, and in addition it has the ability to accumulate higherconcentrations of osmoprotectants.Thus, this survey identified that some accessions of Andean lupin were able to avoid drought stress throughstomatal traits and root traits, and others that were able to tolerate drought through the accumulation ofosmotically active substances. Consequently, there are good prospects for breeding of Andean lupin toimprove its drought resistance.

Full textAbstract:
Andean lupin in Europe has regained interest in recent years due to its high seed protein and oil content and its potential use for food, feed as well as a crop used in biorefineries. A search for suitable germplasm in combination with a determination of appropriate agronomical practices such as planting date are needed for commercial farming in new areas. The current study aims to evaluate the performance of six selected L. mutabilis accessions in a Mediterranean area using two different planting dates for two consecutive experimental years. A split plot design with accessions as subplots and planting dates as main plots was used. Measurements such as days to flowering, plant height, total number of pods and seeds per plant, seed yield and seed crude protein content were taken. All accessions performed better when cultivation started not later than the end of autumn since high temperatures occurred during late spring shortened the growth cycle and reduced yield. Earlier cultivation applied, in the middle of autumn, did not enhance significantly seed yield production. Among the accessions, LIB223 was characterized by the highest seed crude protein content in the early planting treatment, while accessions with prolonged growth cycle (LIB209, LIB214 and LIB223) produced higher seed yield than other accessions and could be further studied as promising breeding material for cultivation under the edaphoclimatic conditions tested.

Mestrado em Engenharia Agronómica / Instituto Superior de Agronomia. Universidade de LisboaLupinus mutabilis is a little-known species. Originating in the Andean region, its propagation worldwide is still deficient or has yet to occur, contrary to what happened to other lupin species. Despite this, within its genus, it is one of the most promising species, being even considered as a good alternative to soy, the world’s leading protein crop. The benefits of pulses in health are already well documented and studied, and many of these foods provide health benefits that go beyond high nutrient value, by containing several compounds that exhibit very interesting bioactivities. Many of these bioactivities have been discovered and studied in several pulses. Still, in L. mutabilis, these bioactivities are yet, for the most part, unknown. The aim of the present work is to assess the presence of deflamin in L. mutabilis, a small polypeptide oligomer with strong anti-inflammatory and anti-tumor potential, previously discovered in our research group in L. albus. The total protein extract of L. mutabilis seeds was tested for any inhibitory potential towards MMP-9. All eleven tested accessions showed inhibitory activity towards these metalloproteinases, with three standing out: JKI-210, JKI-295 and SBP. Through a reverse zymography performed under denaturing conditions a small polypeptide, with approximately 20 kDa, was detected. This was the first indication that deflamin could be present in the seeds of this lupin species, similarly to L. albus. Using a patented extraction method deflamin was isolated and then tested in vitro in HT29 cell migration assays. Accession JKI-210 stood out in the performed tests for having the highest inhibitory potential towards the activity of MMP-9. Field trials, performed in Tapada da Ajuda, Lisboa, showed that this accession, although being slightly less productive, adapted well to the Mediterranean near-coastal climate, suggesting it may be perfectly adequate to be sown in this area. The present work concludes that deflamin is present in L. mutabilis seeds, with significant bioactivity. This new discovery adds another valuable feature to an already promising crop

Full textAbstract:
The recent excavations of two important areas of the Pachacamac Monumental Sector, the foot of the principal facade of the Old Temple and the area beneath the hall of the main entrance at the Temple of the Sun, have allowed the authors to determine the relative chronology of the first construction at this site during the Early Intermediate Period. The ceramic fragments recovered share similar technological, formal and iconographic characteristics with the Lima Medio ceramics (Lima 4-5 in the Patterson sequence) from Chancay, Chillon and Ancon. This paper concurs with the hypothesis that after the conquest of the lower Rimac and Lurin valleys, there was an emerging regional multi-valley political entity which could relate to a complex chiefdom or an “Andean State.” However, during the Lima occupation of the Pachacamac site there is no evidence of an administrative center with urban residential zones. Instead, Pachacamac seems to have been a low-ranked local ceremonial center compared with the sites of Maranga, Pucllana or Cajamarquilla.Las excavaciones llevadas a cabo por los autores en dos lugares claves del complejo monumental de Pachacamac, al pie de la fachada sur del Templo Viejo y debajo del vestíbulo de la entrada principal al Templo del Sol, han permitidodeterminar con precisión, la cronología relativa del inicio de obras de construcción, emprendidas durante el Periodo Intermedio Temprano, en el área del famoso santuario, ubicado sobre la margen izquierda del río Lurín, en los suburbios de Lima. El material cerámico asociado a los niveles de ocupación tiene las mismas características tecnológicas, formales e iconográficas que la cerámica Lima Medio (Lima 4-5 según Patterson (2014[1966]) en los valles de Chancay y Chillón, así como en Ancón. Cambios simultáneos, profundos, y de gran escala, se hacen presentes durante las fases Lima Medio en la Costa Central del Perú. Las tecnologías de producción de cerámica, su decoración, las técnicas de construcción, las formas de arquitectura, y los rituales funerarios, originarios de la cuenca de Chillón y de Ancón fueron adoptadas por laspoblaciones de Rímac y Lurín. Estas evidencias hacen reforzar la hipótesis que luego de la conquista de los valles bajos de Rímac y Lurín se está formando una entidad política regional multivalle con características de jefatura compleja y/o del «estado andino». Pachacamac lima no tuvo características de un centro administrativo con zonas urbanas residenciales, sino más bien las de un centro ceremonial local, posiblemente de rango subalterno, a juzgar por la comparación con Maranga, Pucllana y Cajamarquilla.
