Abstract:
Floral morphology and its relationship to pollination syndromes is examined, for the genera Brunsvigia and Crossyne (Amaryllidaceae). These two genera have similar vegetative morphologies and share the same mode of seed dispersal (anemogeochory). They differ in their floral and inflorescence structures. The species Brunsvigia bosmaniae and Crossyne flava are chosen as representative species of the two genera Brunsvigia and Crossyne. Floral morphology is studied in relationship to an outgroup species Nerine humilis. Pollination syndrome, ability to self-pollinate, levels of natural seed set and patterns of seed dispersal are studied so that reproductive strategies pf the two species can be compared. Crossyne flava is pollinated by a suite of small diurnal insects and can be considered to have a generalist pollination syndrome. The first observation of pollination by moths in Brunsvigia bosmaniae is reported. I show that neither species is able to self, hence pollination events are important. Experimental manipulation reveals that Brunsvigia bosmaniae is pollinator limited. Although this experimental manipulation was not possible for Crossyne flava, high seed set levels in Crossyne flava suggests that levels of pollination are high in Crossyne and low for Brunsvigia. The amount of pollination that takes place is shown to be closely related to floral morphology. Floral divergence of the two genera is thus proposed to be the result of adaptation to a pollinator driven selective regime.

Abstract:
Les Ranunculales sont un ordre d’angiospermes d’environ 4500 espèces, incluant des plantes communes comme les boutons d’or et les coquelicots. Leurs fleurs sont très diversifiées et ont piqué l’intérêt des botanistes depuis des décennies. Les sept familles de l’ordre sont faciles à reconnaître sur le terrain, mais paradoxalement, certaines familles n’ont pas de synapomorphies et ont des états ancestraux peu clairs, comme les Ranunculaceae (~ 2500 espèces). Cette diversité florale peut être liée à la pollinisation et des innovations ont pu être guidées par cette interaction. De plus, les plantes de ce groupe produisent une grande variété de composés secondaires, certains dont les propriétés sont connues depuis fort longtemps (comme la morphine et le curare). Ces substances pourraient jouer un rôle dans la défense contre les herbivores. Les caractères floraux et chimiques sont donc de bons candidats pour produire des hypothèses adaptatives. Ici nous utilisons des méthodes analytiques modernes pour comprendre les patrons d’évolution expliquant la distribution actuelle de la diversité et l’évolution des fleurs et des toxines de Ranunculales. Un nouveau cadre phylogénétique synthétique a été produit avec des séquences publiées de 144 espèces. Seize caractères floraux et la présence de certains composés métaboliques ont été reconstruits sur cet arbre avec la méthode de parcimonie et la méthode de « Reversible Jump Monte Carlo Markov Chains ». Un nouveau scénario d’évolution florale a été produit, où les Ranunculales avaient une fleur ancestrale trimère avec trois cycles de tépales et où les ancêtres des familles ont évolué en perdant ou en différenciant des cycles du périanthe. Les patrons d’évolution des toxines montrent de la variabilité, certaines apparaissant et disparaissant aléatoirement (comme les saponines), d’autres étant des synapomorphies bien soutenues de certains clades (comme les diterpènes de type aconitine pour la tribu des Delphinieae). Ces résultats offrent une meilleure compréhension de l’histoire naturelle des Ranunculales. En outre, cet ordre est le groupe-frère de toutes les autres eudicotylédones, et a donc une position clef pour comprendre l’évolution précoce de ce clade. Ces résultats vont fournir une compréhension plus profonde des changements floraux et phytochimiques qui ont eu lieu à la base des eudicotylédones, qui contiennent 70% des angiospermes actuelles
Ranunculales are an order of angiosperms comprising ca. 4,500 species including common plants like buttercups and poppies. Their flowers are highly diversified and have raised the interest of botanists for decades. Each of the seven families of the order is easily recognizable in the field, but paradoxically some families lack floral synapomorphies and have unclear ancestral states, like Ranunculaceae (ca. 2,500 species). This floral diversity may be linked to pollination and innovations may have been driven by this interaction. In addition, the plants of this group produce a variety of secondary compounds, some of which having been known for ages for their properties, like morphine or curare. Those substances could play a role in defense against herbivores. Both floral and chemical characters are thus good candidates to produce adaptive hypotheses. Here we used modern analytical methods to understand the the evolutionary patterns accounting for the extant distribution of diversity and evolution of Ranunculales flowers and toxins. A new synthetic phylogenetic framework of the Ranunculales based on already available sequences of 144 species was produced. Sixteen characters of the flower, and the presence of selected secondary metabolites were reconstructed on this tree using parsimony, and Reversible Jump Monte Carlo Markov Chains. A new scenario for floral evolution was produced, where Ranunculales had a trimerous perianth with three whorls of tepals ancestor, and the ancestors of the families evolved by losing and/or differentiating perianth whorls. The evolutionary patterns of toxins showed variability, some appearing and disappearing randomly (such as saponins), others being well-supported synapomorphies (such as aconitine-like diterpens for the tribe Delphinieae). These results offer a better understanding of the natural history of Ranunculales. Furthermore, this order is the sister-group of all other eudicots, and thus has a key position to understand the early evolution of this clade. These results will provide a deeper understanding of the floral and chemical changes that took place at the base of eudicots, which contains 70% of living angiosperms

Abstract:
A utilização de Bromélias tem sido crescente no mercado de plantas onamentais, por outro lado, muitas espécies encontram-se ameaçadas, grande parte pelos impactos humanos no ambiente. Aechmea correia-araujoi E. Pereira & Moutinho, Aechmea gamossepala Wittm, Vriesea ensiformis (Vell.) Beer e Vriesea saundersii (Carrière) E. Morren ex Mez, espécies nativas da Mata Atlântica brasileira, têm sido alvo de extrativismo. Informações básicas sobre a espécie são essenciais para subsidiar a condução de programas de conservação e melhoramento genético, que aliados a ferramentas biotecnológicas permitem a incorporação de estratégias inovadoras aos métodos de melhoramento. Neste sentido, o objetivo do presente trabalho foi descrever essas espécies, quanto à micromorfologia floral, aspectos reprodutivos envolvidos no processo de polinização, desenvolvimento floral e deesenvolvimento gametofítico, como mecanismo de preservação e produção comercial. A caracterização morfológica e anatômica das flores das espécies de Aechmea e Vriesea contribuiu para a compreensão do processo reprodutivo. As espécies apresentam grãos de pólen com alta capacidade reprodutiva, viabilidade polínica superior a 93%, germinação in vitro maior que 80% e o estigma apresenta-se receptivo da antese ao final do dia. A ontogênese floral de A. correia-araujoi é centrípeta, os primórdios desenvolvem-se na ordem, sépala, pétala, androceu e gineceu. O apêndice petalar é formado na fase final do desenvolvimento. O primórdio de óvulo tem origem placentária e caráter trizonal, o óvulo é anátropo, bitegumentado e crassinucelado. O meristema floral de A. gamosepala se desenvolve de forma centrípeta, de forma unidirecional reversa. O estigma diferencia-se na fase inicial do desenvolvimento e os apêndices petalares, na fase final. O óvulo é anátropo, crassinucelado, bitegumentado, tétrade linear, megásporo calazal funcional, desenvolvimento tipo monospórico e Polygonum. As anteras são bitecas, tetraesporangiadas, com tapete secretor. Botões florais de 8,7 - 13,0 mm são indicados no estudo de embriogênese a partir de micrósporo. As alterações celulares e o padrão de distribuição de pectinas e AGPs foram caracterizadas por análise citoquímica com azul de toluidina, KI e DAPI e imunocitoquímica por imunofluorescência com os anticorpos para RNA, pectinas esterificadas (JIM7), não esterificadas (JIM5) e AGPs (LM2, LM6, MAC207, JIM13, JIM14) e analisadas por microscopia de fluorescência. Foram caracterizados padrões de distribuição espaço-temporal de pectinas e AGP que podem ser utilizados como marcadores de desenvolvimento gametofítico masculino. As observações feitas nesse trabalho fornecem dados sobre aspectos reprodutivos das espécies que podem ser utilizados em programas de melhoramento genético, conservação e desenvolvimento de haploides
The use of bromeliads has grown in the ornamental market, however many native species are threatened, mostly due to human impacts. Basic information about the species is essential to support breeding and conservation programs, which combined with biotechnological tools allow for the innovative approaches to breeding methods. The objective of this study was to characterize the floral development and reproductive aspects of the ornamental species Aechmea correia-araujoi, Aechmea gamosepala, Vriesea ensiformis and Vriesea saundersii, with detais on floral morphology and anatomy, reproductive aspects involved in pollination. For the Aechmea species the gametophytic development was characterized, as well as the cellular changes that occur during the development of the male gametophyte, characterizing the distribution pattern of pectin and arabinogalactan proteins (AGPs), for biotechnological applications. The plants were characterized by observations of the material in the greenhouse and floral organs were described using microscopic techniques. The flowers are actinomorphic, trimerous, dichlamydeous, heterochlamydeous, with double petal appendages, six stamens, gamocarpelar, tricarpellate ovary, with septal nectaries and a large number of ovules. Aspects of the floral biology involved in reproduction were assessed by stigma receptivity, pollen morphology, viability and in vitro pollen grain germination. The species produce large amounts of pollen grains with high reproductive capacity, pollen viability higher than 93%, in vitro germination higher than 80% and stigma is receptive throughout the day. The floral ontogeny of A. correia-araujoi is centripetal, the primordia develop sepals, petals, stamens and pistil. The petal appendages are formed in the final stages of floral development. The cellular changes, and the distribution pattern of pectins and AGPs were characterized by cytochemical analysis with IKI and DAPI, and immunocytochemistry and immunofluorescence with antibodies for RNA, esterified pectins (JIM7) de-esterified (JIM5) and AGPs (LM2 , LM6, MAC207, JIM13, JIM14) and analyzed by confocal microscopy. Various spatio-temporal distribution patterns of pectins and AGPs were characterized and may be used as male gametophyte development markers. The observations made in this work provide data on reproductive aspects of the species studied, and can be further used in breeding and conservation programs, and haploid production

It is the occasion in which scholars can illustrate and exchange their activities and innovative proposals, with common aims to promote actions to preserve coastal marine environment. Considering Symposium interdisciplinary nature, the Scientific Committee, underlining this holistic view of Nature, decided to celebrate Alexander von Humboldt; a nature scholar that proposed the organic and inorganic nature’s aspects as a single system. It represents a sign of continuity considering that in-presence Symposium could not be carried out due to the COVID-19 pandemic restrictions. Subjects are related to coastal topics: morphology; flora and fauna; energy production; management and integrated protection; geography and landscape, cultural heritage and environmental assets, legal and economic aspects.

Abstract:
The delta land Bangladesh has a unique coastline where numerous rivers meet the Bay of Bengal, creates a complex net of tidal river estuaries, forming the base for world’s largest mangrove forest the Sundarbans. Chalna is small town located at the confluence of Rupsha and Chunkuri rivers, only 9 km north of the Sundarbans, and a well know river port. The Sundarbans, which acts as a buffer between the sea and the human habitats including arable lands. The forest is rich in unique biodiversity and natural resources providing livelihoods of a large number of people living in the towns and villages around it. As the region is near the sea and land morphology is plain and of low altitude it is always vulnerable to natural disasters. Due to global warming and sea level rising the land mass is vulnerable to flooding. The sign of climate change; erratic behavior of rainfall and draught, intrusion of salinity etc., are changing the usual pattern of agriculture and fishing, affecting the livelihoods of the people here. The eco system of this mangrove forest is also threatened by recent policies of the Government and initiatives of private sectors of establishing high risk industrial establishments like thermal power plant, liquid petroleum gas stations etc., around Chalna and its surrounding region in sprawling manner. The potential of running large number of vessels through the rivers and canals of the Sundarbans might have negative impacts of the flora and fauna living there. Popular protests against these harmful interventions are being observed, international public organizations and concerned learned societies are also recommending not let these damaging developments going on. Although there are some promises from the government to the international agencies, there is no sign of management of such developments. This paper systematically investigates the reasons of this phenomenon, identifies the challenges and concludes that; absence of regional spatial planning in Bangladesh, neglecting the values of environment and public goods, defying the regulations in various ways and not accounting public opinions in the decision making process are the core ones.

Abstract:
Background and objectives: Manipulation of plant organ growth is one of the primary reasons for the success of mankind allowing increasing amounts of food for human and livestock consumption. In contrast with the successful selection for desirable growth characteristics using plant breeding, transgenic manipulations with single genes has met limited success. While breeding is based on accumulation of many small alterations of growth, usually arise from slight changes in expression patterns, transgenic manipulations are primarily based on drastic, non-specific up-regulation or knock down of genes that can exert different effects during different stages of development. To successfully harness transgenic manipulation to attain desirable plant growth traits we require the tools to subtly regulate the temporal and spatial activity of plant growth genes. Polar morphology along the adaxial/abaxial axis characterizes lateral organs of all plants. Juxtaposition of two cell types along this axis is a prerequisite of laminar growth induction. In the study summarized here, we addressed the following questions: Can we identify and harness components of the organ polarity establishment pathway for prolonged growth? Can we identify specific regulatory sequences allowing spatial and temporal manipulation in various stages of organ development? Can we identify genes associated with YABBY-induced growth alterations? Major conclusions and implications: We showed that regulated expression, both spatially and temporally of either organ polarity factors such as the YABBY genes, or the organ maturation program such as the CIN-TCPs can stimulate substantial growth of leaves and floral organs. Promoters for such fine manipulation could be identified by comparison of non-coding sequences of KAN1, where a highly conserved domain was found within the second intron, or by examination of multiple 5” regions of genes showing transient expression along leaf ontogeny. These promoters illustrate the context dependent action of any gene we examined thus far, and facilitate fine tuning of the complex growth process. Implications, both scientific and agricultural. The present study was carried out on the model organism Arabidopsis, and the broad application of its findings were tested in the tomato crop. We learned that all central regulators of organ polarity are functionally conserved, probably in all flowering plants. Thus, with minor modifications, the rules and mechanisms outlined in this work are likely to be general.
