Isolation, characterization and selection of indigenous Bradyrhizobium strains with outstanding symbiotic performance to increase soybean yields in Mozambique por Chibeba, A.M., Boahen, S., Fátima Guimarães, M. de, Nogueira, M.A., Hungria, M.

“…Five isolates, three (Moz 4, Moz 19 and Moz 22) belonging to the superclade B. elkanii and two (Moz 27 and Moz 61) assigned to the superclade B. japonicum, consistently showed high symbiotic effectiveness, suggesting that the inoculation with indigenous rhizobia adapted to local conditions represents a possible strategy for increasing soybean yields in Mozambique. Phylogenetic position of the five elite isolates was confirmed by the MLSA with four protein-coding housekeeping genes, dnaK, glnII, gyrB and recA.…”

Genotyping-by-sequencing provides the discriminating power to investigate the subspecies of Daucus carota (Apiaceae) por Arbizu Berrocal, Carlos Irvin, Ellison, Shelby L., Senalik, Douglas, Simon, Philipp W., Spooner, David M.

“…Conclusions: Our study suggests that (1) the morphotypes identified as D. carota subspecies gummifer (as currently broadly circumscribed), all confined to areas near the Atlantic Ocean and the western Mediterranean Sea, have separate origins from sympatric members of other subspecies of D. carota, (2) D. carota subsp. maximus, on two clades with some accessions of subsp. carota, can be distinguished from each other but only with poor morphological support, (3) D. carota subsp. capillifolius, well distinguished morphologically, is an apospecies relative to North African populations of D. carota subsp. carota, (4) the eastern cultivated carrots have origins closer to wild carrots from central Asia than to western cultivated carrots, and (5) large SNP data sets are suitable for species-level phylogenetic studies in Daucus…”

Unlocking the complete chloroplast genome of a native tree species from the Amazon Basin, capirona (Calycophyllum spruceanum, Rubiaceae), and Its comparative analysis with other Ix... por Saldaña Serrano, Carla Lizet, Rodriguez Grados, Pedro Manuel, Chávez Galarza, Julio César, Feijoo Narvasta, Shefferson Gilbert Wilson, Guerrero Abad, Juan Carlos, Vásquez Pérez, Héctor Vladimir, Maicelo Quintana, Jorge Luis, Jhoncon, Jorge H., Arbizu Berrocal, Carlos Irvin

“…Whole chloroplast genome comparison with the other six Ixoroideae species revealed that the small single copy and large single copy regions showed more divergence than inverted regions. Finally, phylogenetic analyses resolved that C. spruceanum is a sister species to Emmenopterys henryi and confirms its position within the subfamily Ixoroideae. …”

Two novel flavi-like viruses shed light on the plant-infecting koshoviruses por Debat, Humberto Julio, Bejerman, Nicolas Esteban

“…Structural and functional annotations of the polyproteins of all koshoviruses resulted in the detection not only of the expected helicase and RNA-dependent RNA polymerase but also of several additional divergent domains, including AlkB oxygenase, trypsin-like serine protease, methyltransferase, and envelope E1 flavi-like domains. Phylogenetic analysis showed that CopFLV1, SonFLV1, GKaV, and the carrot flavi-like virus were grouped together in a monophyletic clade, strongly supporting the recent proposal for creation of the genus “Koshovirus” for the group of related plant-infecting flavi-like viruses.…”

Analysis of 13000 unique Citrus clusters associated with fruit quality, production and salinity tolerance por Terol, Javier, Conesa, Ana, Colmenero-Flores, José M., Cercós, Manuel, Tadeo, Francisco R., Agustí, Javier, Alos, Enriqueta, Andres, Fernando, Soler, Guillermo, Brumos, Javier, Iglesias, Domingo J., Gotz, Stefan, Legaz, Francisco, Argout, Xavier, Courtois, Brigitte, Ollitrault, Patrick, Dossat, Carole, Wincker, Patrick, Morillon, Raphael, Talón, Manuel

“…Conclusion: Comparative genomics with Arabidopsis revealed the presence of putative conserved orthologs and single copy genes in Citrus and also the occurrence of both gene duplication events and increased number of genes for specific pathways. In addition, phylogenetic analysis performed on the ammonium transporter family and glycosyl transferase family 20 suggested the existence of Citrus paralogs. …”

Differential expression of IDA (INFLORESCENCE DEFICIENT IN ABSCISSION)- like genes in Nicotiana benthamiana during corolla abscission, stem growth and water stress por Ventimilla, Daniel, Domingo, Concha, González-Ibeas, Daniel, Talón, Manuel, Tadeo, Francisco R.

“…In this work, we determined the conservation and phylogeny of the IDA-like and HAE-like gene families in relevant species of the Solanaceae family and analyzed the expression of these genes in the allopolyploid Nicotiana benthamiana, in order to identify members involved in abscission, stem growth and in the response to drought conditions. Results The phylogenetic relationships among the IDA-like members of the Solanaceae studied, grouped the two pairs of NbenIDA1 and NbenIDA2 protein homeologs with the Arabidopsis prepropeptides related to abscission. …”

Highly GC-rich heterochromatin in chili peppers (Capsicum-Solanaceae): A cytogenetic and molecular characterization por Grabiele, Mauro, Debat, Humberto Julio, Scaldaferro, Marisel Analía, Aguilera, Patricia Mabel, Moscone, Eduardo Alberto, Seijo, José Guillermo, Ducasse, Daniel Adrian

“…We physically mapped six Capsicum derived specific 18S-25S rDNA probes that covered the entire span of the rDNA unit and analysed a DraI restriction product on eight chromosomally different taxa of Capsicum, representative of the major phylogenetic clades of chili peppers. The co-localization of every gene and spacer probes of the 18S-25S rDNA unit suggest their structural function as a major repetitive component of the highly GC-rich cHet in Capsicum species with x = 12. …”
