Abstract:

Genetic resistance against biotic stress is a major goal in many wheat breeding programs. However, modern wheat cultivars have a limited genetic variation for disease and pest resistance and there is always a possibility of the evolution of new diseases and pests to overcome previously identified resistance genes. A total of 125 synthetic hexaploid wheats (SHWs; 2n = 6x = 42, AABBDD, Triticum aestivum L.) were characterized for resistance to fungal pathogens that cause wheat rusts (leaf; Puccinia triticina, stem; P. graminis f.sp. tritici, and stripe; P. striiformis f.sp. tritici) and crown ro

Abstract This study investigated the role of endogenous Palestinian plant extracts in inducing wheat and barley resistance systems against loose smut disease with the aim to alternate the chemical pest control with natural fungicides. Twenty indigenous herbal plant extracts and essential oils were assessed for their biological and antifungal properties against Ustilago tritici and Ustilago nuda. Their potential role in inducing resistance pathways was studied on four different cultivars of wheat and barley.

Abstract:

Wide crosses in wheat have now been performed for over 100 years. In that time, approximately 100 genes have been transferred for numerous traits, including biotic and abiotic stresses and value-added traits. Resistance genes from alien sources do become defeated with time, so the search for additional variability must continue. Recent screening of alien species has identified accessions with multiple pest resistance plus combinations of pest resistance and value-added traits. The majority of existing induced recombinants are of a noncompensating type with considerable linkage drag, so sequent

Every crop breeding effort seeks to enhance production. Despite several advances, most worldwide breeding efforts have long sought to improve grain production potential, insect/pest/disease resistance, grain quality, and stress tolerance. Almost all wheat breeding programs aim to increase grain yield potential. Wheat breeders have achieved substantial improvements in crop yield. Genetic transformation, cloning, and genetic engineering increase production potential in wheat. The primary breeding strategy for wheat is the pedigree.

Wild grasses, including relatives of wheat, have several desirable characters that can be introduced into both bread wheat and durum wheat. Since current wheat cultivars lack certain traits, for example, resistance to fusarium head blight (scab), related wild grasses may be the only option for useful variability. Wide hybridization of wheat with grasses, coupled with cytogenetic manipulation of the hybrid material, has been instrumental in the genetic improvement of wheat.

A combination of recombinant-inbred lines of the F6 generation from the cross B-16 ќ AR 7086 between lines with two wheat-rye translocations, 1BL/1RS from the Petkus and 1AL/1RS from the rye Insave, was developed. Using gliadin and secalin loci as genetic markers we identified recombinant arm 1RS in positions 1A and 1B in about 10% of lines. The rest of lines with the rye material may also carry recombinant 1RS, which can be identified with DNA markers. Lines with recombinant arm 1RS may serve as a source of new combination of rye genes for disease and pest resistance.

Ingestion of wheat, barley, or rye triggers small intestinal inflammation in patients with celiac disease.

This well-defined role of adaptive immunity contrasts with an ill-defined component of innate immunity in celiac disease.

This paper reviews and discusses the literature pertaining to the D. noxia R-genes on chromosome 7D, and markers reported to be associated with them. Individual plants with known phenotypes from a panel of South African wheat accessions are used as examples. Despit

AbstractNine winter wheat cultivars (Triticum aestivum Linnaeus) (Poaceae) were the source of the Sm1 gene for resistance to wheat midge, Sitodiplosis mosellana (Géhin) (Diptera: Cecidomyiidae), in spring wheat. All nine showed antibiosis characteristic of Sm1, as expected. They also showed oviposition deterrence and reduced hatch, which contributed to overall resistance. The overall level of resistance of the nine winter wheat cultivars was usually lower than that of resistant spring wheat lines in laboratory trials, but equally high in a field trial. Five of seven other North American winter

Abstract:

The greenbug Schizaphis graminum, is a major pest of wheat worldwide. Biotype screening of this pest is essential to develop pest management programs. In this research, eight greenbug clones, collected on wheat in the cereal-growing region of Béja (north Tunisia), were used to determine their damage on six reference wheat cultivars. All tested clones shared a unique biotypic profile, similar to biotype C. Moreover, DNA from the tested clones and that from seven reference clones of biotypes C, E, F, G, H, I and K, was analyzed, using 5 RAPD-PCR primers. The UPGMA method clustered samples into t

Abstract:

Breeding for disease resistance is a central focus of plant breeding programs, as any successful variety must have the complete package of high yield, disease resistance, agronomic performance, and end - use quality. Wheat breeding is focused on high yield, pathogen resistance and abiotic stress tolerance. Among diseases of wheat yellow rust, stem rust, and leaf rust are the most damaging diseases of wheat and other small grain cereals . Disease resistance in wheat breeding with one exception, the diseases of wheat that is important because of their effect on yield. Resistance to all diseases

The pest greenbug Schizaphis graminum (Rondani) (Hemiptera: Aphididae) stands out among the factors limiting Brazilian wheat production. Chemical control is predominant in aphid management making the production dependent on insecticides. The effect of silicon and previous infestation with aphids on the induction of resistance to the greenbug was evaluated in wheat plants. Treatments consisted of control; fertilization with calcium silicate; plant infestation with aphids; fertilization with calcium silicate + plant infestation with aphids.

Abstract:

Resistant cultivars offer a pathway to sustainable intensification by maintaining yields and reducing inputs in the face of disease pressure. Past studies of economic returns to crop breeding research for disease resistance measured farm-level benefits, by comparing yields for improved resistant varieties (RVs) to susceptible traditional varieties. This approach will poorly approximate actual research benefits if non-RV pest management options exist, because it does not account for farmer pest control behavior. We propose a unit cost model that controls for farm-level yields and pesticide inpu

With the expansion of the area under Cruciferae vegetable cultivation, and an increase in the incidence of natural threats such as pests and diseases globally, Cruciferae vegetable losses caused by pathogens, insects, and pests are on the rise. As one of the key metabolites produced by Cruciferae vegetables, glucosinolate (GLS) is not only an indicator of their quality but also controls infestation by numerous fungi, bacteria, aphids, and worms. Today, the safe and pollution-free production of vegetables is advocated globally, and environmentally friendly pest and disease control strategies, s
