Macauba [Acrocomia aculeata (Jacq.) Lodd. ex Mart.], a palm tree native to Brazil, has a high potential as an alternative source for vegetal oil production. It has several applications in the cosmetics, pharmaceuticals and food industries, and for the production of biofuels. The conservation and characterization of its germplasm are essential for progress in genetic improvement. In this sense, a study of genetic divergence was carried out based on predicted genetic values of 88 accessions form the Active Germplasm Bank of Macauba of EMBRAPA (Brazilian Agricultural Research Corporation). Seven morpho-agronomic characters were observed. The obtained dendrogram generated seven groups. There was a tendency to group accessions according to geographic origin. The graphical dispersion of accession scores plotted in a two-dimensional space showed a pattern correlated to the clusters observed in the dendrogram. The first two principal components (PC1 and PC2) explained 70.4% of the total divergence. The most important traits associated with PC1 and PC2 were the number of fruit bunches and fruit volume, respectively. The application of mixed models in the study of divergence was useful in structuring the germplasm. The structuring of the germplasm is crucial to assist in the choice of parents aiming the selection of recombinant individuals with a superior performance in segregating generations. |

Nitrogen-fixing symbiosis is globally important in ecosystem functioning and agriculture,yet the evolutionary history of nodulation remains the focus of considerable debate. Recentevidence suggesting a single origin of nodulation followed by massive parallel evolutionarylosses raises questions about why a few lineages in the N2-fixing clade retained nodulationand diversified as stable nodulators, while most did not. Within legumes, nodulation isrestricted to the two most diverse subfamilies, Papilionoideae and Caesalpinioideae, whichshow stable retention of nodulation across their core clades.We characterize two nodule anatomy types across 128 species in 56 of the 152 genera ofthe legume subfamily Caesalpinioideae: fixation thread nodules (FTs), where nitrogen-fixingbacteroids are retained within the apoplast in modified infection threads, and symbiosomes,where rhizobia are symplastically internalized in the host cell cytoplasm within membrane-bound symbiosomes (SYMs).Using a robust phylogenomic tree based on 997 genes from 147 Caesalpinioideae genera,we show that losses of nodulation are more prevalent in lineages with FTs than those withSYMs.We propose that evolution of the symbiosome allows for a more intimate and enduringsymbiosis through tighter compartmentalization of their rhizobial microsymbionts, resulting ingreater evolutionary stability of nodulation across this species-rich pantropical legume clade. |
