DarT_seq; Early selection; Linkage disequilibrium; Molecular markers; Selective accuracy

Genome wide selection (GWS) is essential for the genetic improvement of perennial species such as Citrus because of its ability to increase gain per unit time and to enable the efficient selection of characteristics with low heritability. This study assessed GWS efficiency in a population of Citrus and compared it with selection based on ... more

Centroid method; HMRPGV method; Phaseolus vulgaris

The common bean, Phaseolus vulgaris, is predominantly grown on small farms and lacks accurate genotype recommendations for specific micro-regions in Brazil. This contributes to a low national average yield. The aim of this study was to use the methods of the harmonic mean of the relative performance of genetic values (HMRPGV) and the centroid, for ... more

CMA/DAPI; cytotaxonomy; Jacaranda; Karyotypic variation; Terminal heterochromatin

Most taxa in the Bignoniaceae have 2n = 40, but the basal clade Jacarandeae has 2n = 36, suggesting that x = 18 is the ancestral basic number for the family. Variations in heterochromatin band patterns in genera that are numerically stable, such as Jacaranda, could facilitate our understanding of the chromosomal and karyotypic ... more

Bioinformatic analysis; Gene expression; MYB10; Red-leaf peach

In higher plants, the transcription factor MYB10 is an important regulator of anthocyanin biosynthesis. In order to study its role in the development of red coloration in peach leaves, the full-length MYB10 complementary DNA sequence of the red-leaf peach cultivar ‘Tsukuba No. 5’ (Prunus persica f. atropurpurea) was successfully cloned ... more

Abiotic stress; Arabidopsis thaliana; Glycine-rich protein; Lablab purpureus

Glycine-rich protein (GRP) is involved in the response to abiotic and biotic stresses in plants. A novel GRP gene in Lablab purpureus has been identified. The cDNA of LpGRP was obtained from an SSH library constructed with root tissues of L. purpureus MEIDOU 2012 by waterholding for 10 days. The function of LpGRP was also ... more

Gynophore; MicroRNA sequencing; peanut

Peanut is one of the most important oilseed crops in the world that provides a significant amount of lipids and protein for many people. The gynophore plays an important role in gynophore development after fertilization of the peanut ovule. MicroRNAs (miRNAs) play an important role in numerous developmental and physiological plant ... more

Chloroplast DNA; Demographic history; Molecular evolution; Polymorphism; Quercus suber L.; trnL-trnF spacer

Sequences of the trnL-trnF spacer and combined trnL-trnF region in chloroplast DNA of cork oak (Quercus suber L.) were analyzed to detect polymorphisms and to elucidate molecular evolution and demographic history. The aligned sequences varied in length and nucleotide composition. The overall ratio of transition/ ... more

Pimpinella L. is a large genus and arguably one of the most complex genera in the family Apiaceae. In this study, the infra-generic relationship between Southwest Asian Pimpinella species and their generic allies in the tribe Pimpinelleae Spreng were investigated using sequence data from the cpDNA (chloroplast DNA) rps16 exon and ... more

Dipterocarps; Dipterocarpus costatus; Genetic conservation; Genetic variability; Simple sequence repeats

Dipterocarpus costatus is an endangered species restricted to the lowland forests of southern Vietnam. Habitat loss and over-exploitation of D. costatus wood are the major threats to this species. We investigated the level of genetic variability within and among populations of D. costatus in order to provide ... more

Chromosomes; Cytogeography; Karyotype; Myrtaceae; Neotropics; Polyploidy

Polyploidy is one of the most important mechanisms of speciation and diversification in plant evolution. Polyploidy results in genetic variation among individuals of the same species and even between populations, and may be responsible for differences in environmental tolerance between populations of the same species. This study determined chromosome numbers of ... more
