Open AccessSex effect on growth performance and marker-aided sex discrimination of seedlings of Populus deltoides
Sex has a significant effect on various traits among dioecious plants. In this analysis of the sex effect on the radial growth and wood density of numerous 20-year-old trees of Populus deltoides growing in a comm...

Open AccessEvidences for a role of two Y-specific genes in sex determination in Populus deltoides
Almost all plants in the genus Populus are dioecious (i.e. trees are either male or female), but it is unknown whether dioecy evolved in a common ancestor or independently in different subgenera. Here, we sequenc...

Open AccessGossypium barbadense and Gossypium hirsutum genomes provide insights into the origin and evolution of allotetraploid cotton
Allotetraploid cotton is an economically important natural-fiber-producing crop worldwide. After polyploidization, Gossypium hirsutum L. evolved to produce a higher fiber yield and to better survive harsh environ...

Open AccessGenomic insights into divergence and dual domestication of cultivated allotetraploid cottons
Cotton has been cultivated and used to make fabrics for at least 7000 years. Two allotetraploid species of great commercial importance, Gossypium hirsutum and Gossypium barbadense, were domesticated after polyplo...

Open AccessSequence-based ultra-dense genetic and physical maps reveal structural variations of allopolyploid cotton genomes
SNPs are the most abundant polymorphism type, and have been explored in many crop genomic studies, including rice and maize. SNP discovery in allotetraploid cotton genomes has lagged behind that of other crops...

Open AccessSequencing of allotetraploid cotton (Gossypium hirsutum L. acc. TM-1) provides a resource for fiber improvement
Two draft sequences of Gossypium hirsutum, the most widely cultivated cotton species, provide insights into genome structure, genome rearrangement, gene evolution and cotton fiber biology.
