“…To avoid the possible use of misidentified or inaccurate sequences, we included only our own previously generated sequences (e.g. Cardoso et al, 2012aCardoso et al, , 2015 or those from comprehensive phylogenetic analyses of legumes (e.g. Wojciechowski et al, 2004;Bruneau et al, 2008).…”

“…Uncovering the extraordinary diversity of floral architecture in angiosperms through developmental studies provides new insights into evolutionary history and helps us understand phylogenetically obscure or enigmatic relationships that nowadays rely almost exclusively on molecular studies (Saarela et al, 2007;Cardoso et al, 2012aCardoso et al, , b, 2015Ramos et al, 2016). Plants traditionally classified in the paraphyletic subfamily Caesalpinioideae of the big and economically important bean family, Leguminosae, have long been a challenge to a phylogeny-based classification not just because of their phylogenetically unresolved deep nodes, but also because of the dramatic morphological diversity that prevents recognition of clear overall synapomorphies among clades (LPWG, 2013a, b).…”

“…Improved sampling across all clades for reconstructing the legume phylogeny (e.g. Wojciechowski et al, 2004;Lewis et al, 2005;Bruneau et al, 2008;Simon et al, 2009;Cardoso et al, 2012aCardoso et al, , b, 2013 has enabled an evolutionarily comparative look at morphological characters that has revealed e.g. remarkable new insights into the evolution of extrafloral nectaries (Marazzi et al, 2012), the polycarpellate gynoecium (Paulino et al, 2014) and the high persistence of legume-rhizobia symbiosis (Werner et al, 2015).…”

Background and Aims The study of floral morphology and ontogeny and the re-investigation of existing data help to uncover potential synapomorphic characters and foster our understanding of phylogenetic relationships that rely primarily on molecular analyses. Goniorrhachis marginata is a monotypic caesalpinioid legume (Leguminosae) that shows some interesting floral features, such as a long hypanthium and regular Rosaceae-like flowers. We studied the ontogeny and morphology of the flowers in detail and present our results in a broad phylogenetic context.Methods Flower buds were collected in the field, fixed in 70 % ethanol and investigated using scanning electron microscopy. Older buds in spirit were carefully opened to investigate the direction of style bending. Characters of the style from 131 taxa from the main legume lineages were analysed and mapped on a Bayesian molecular phylogeny.Key Results The tetramerous calyx is the result of complete loss of one sepal. The formation of the radially symmetrical corolla starts in a typical caesalpinioid pattern with the adaxial petal innermost (ascending aestivation). The young style bends in the abaxial direction, which is a character found exclusively in all studied detarioid legumes and therefore a newly described synapomorphy for the clade.Conclusions We show that investigation of unstudied taxa and reinvestigation of published data can uncover new, previously overlooked and important characters. Curvature of the style can be detected in young buds with a hand lens and therefore is an important character for field botanists. Our study reveals the importance of including poorly studied and/or phylogenetically enigmatic taxa in molecular phylogenies and in detailed morphological and ontogenetic analyses.

RESUMEN:En el artículo se revisa la importancia y la situación de la conservación de recursos fitogenéticos para la alimentación y la agricultura, tanto en los aspectos asociados específi-camente a esta actividad como en aquellos otros derivados de su faceta como componente de la biodiversidad y proveedor de servicios ecosistémicos. Se incide en la función de las colecciones ex situ como fuente de materiales tanto para su utilización directa como en programas de mejora genética, ambos elementos imprescindibles para una agricultura resiliente frente al cambio ambiental. De forma específica, se describe el estado de la conservación de germoplasma de las especies de la familia de Fabaceae tanto para utilización en alimentación humana como en alimentación animal, en el ámbito nacional e internacional. PALABRAS CLAVE:Recursos fitogenéticos; leguminosas-grano; colecciones de germoplasma; conservación. ABSTRACT:In this article, the importance and situation of the conservation of plant genetic resources for food and agriculture is reviewed, taking into consideration not only the aspects specifically related to the conservation activity but also their role as components of biodiversity and providers of ecosystem services. Special attention is drawn to ex situ collections as providers of germplasm for direct use and for plant breeding, two elements that make an essential contribution to a greater resilience of agriculture to environmental changes. In particular, the state of conservation at national and global levels of genetic resources of Fabaceae species cultivated for human food and animal feed, is examined.

“…This approach may be helpful for studying the Dalbergia clade, in which Aeschynomene genus is included. The Dalbergia clade position in the Papilionoideae phylogeny is well-understood (Cardoso et al, 2012); however, its internal resolution has not been well-defined. Among its taxonomic problems is the genus Aeschynomene, which is split into 2 groups (Ribeiro et al, 2007), including Aeschynomene subgen.…”

Microsatellite in Aeschynomene falcata (Leguminosae): diversity, cross-amplification, and chromosome localization

ABSTRACT. Aeschynomene falcata is an important forage species; however, because of low seed production, it is underutilized as forage species. Aeschynomene is a polyphyletic genus with a challenging taxonomic position. Two subgenera have been proposed, and it is suggested that Aeschynomene can be split in 2 genera. Thus, new markers, such as microsatellite sequences, are desirable for improving breeding programs for A. falcata. Based on transferability and in situ localization, these microsatellite sequences can be applied as chromosome markers in the genus Aeschynomene and closely related genera. Here, we report the first microsatellite library developed for this genus; 11 microsatellites were characterized, with observed and Microsatellite loci in Aeschynomene falcata expected heterozygosities ranging from 0.0000 to 0.7143 and from 0.1287 to 0.8360, respectively. Polymorphic information content varied from 0.1167 to 0.7786. The departure from Hardy-Weinberg equilibrium may have resulted from frequent autogamy, which is characteristic of A. falcata. Of the 11 microsatellites, 9 loci were cross-amplified in A. brevipes and A. paniculata and 7 in Dalbergia nigra and Machaerium vestitum. Five of these 7 cross-amplified microsatellites were applied as probes during the in situ hybridization assay and 2 showed clear signals on A. falcata chromosomes, ensuring their viability as chromosome markers.
