2018-05-31SCBG Reported That Gibberellins Play an Essential Role in Late Embryogenesis of ArabidopsisThe plant hormone gibberellin ( GA ) plays key roles in almost all aspects of plant development , but its detailed function and underlying regulatory mechanism in embryo development are not yet clearly defined .A research team led by Prof . Hou Xingliang from South China Botanical Garden ( SCBG ) of the Chinese Academy of Sciences discovered an ...Read More
The plant hormone gibberellin (GA) plays key roles in almost all aspects of plant development, but its detailed function and underlying regulatory mechanism in embryo development are not yet clearly defined.
Recently, a research team led by Prof. Hou Xingliang from South China Botanical Garden (SCBG) of the Chinese Academy of Sciences d... -
2018-05-08What explains high plant richness in East Asia? Time and diversification in the tribe Lysimachieae (Primulaceae)What causes the disparity in biodiversity among regions is a fundamental question in biogeography , ecology , and evolutionary biology .We find that neither time nor diversification rates alone explain richness patterns among regions in Lysimachieae . Instead , a new index that combines both factors explains global richness patterns in the group...Read More
What causes the disparity in biodiversity among regions is a fundamental question in biogeography, ecology, and evolutionary biology. Evolutionary and biogeographic processes (speciation, extinction, dispersal) directly determine species richness patterns, and can be studied using integrative phylogenetic approaches. However, the strikingly... -
2018-05-04A Series of Researches on The Response of Tree Radial Growth to Global ChangesTree growth of boreal forest plays an important role on global carbon ( C ) cycle , while tree growth in the western Canadian boreal mixed forests has been predicted to be negatively affected by regional drought .Results indicated that tree growth of two species were both primarily affected by competition or tree size , while climatic indices sh... Tree growth of boreal forest plays an important role on global carbon (C) cycle, while tree growth in the western Canadian boreal mixed forests has been predicted to be negatively affected by regional drought. Individual tree growth can be controlled by many factors, such as competition, climate, tree size and age. However, information about con...Read More

2018-02-11Genomic signature of adaptive divergence despite strong non-adaptive forces on edaphic islands: a case study of Primulina juliaeBoth genetic drift and divergent selection are expected to be strong evolutionary forces driving population differentiation on edaphic habitat islands .Populations with the lowest genetic variation were most genetically differentiated from other populations and the extent of genetic drift increased with geographic distance from other populations...Read More
Both genetic drift and divergent selection are expected to be strong evolutionary forces driving population differentiation on edaphic habitat islands. However, the relative contribution of genetic drift and divergent selection to population divergence has rarely been tested simultaneously. In this study, RAD-based population genomic analys... -
2018-02-05Evolutionary transitions from distyly to homostyly: the ecological correlates and genetic consequencesHeterostyly is an adaptation found in numerous families that enables outbreeding in dioecious flowers , complementing self-incompatibility mechanisms .Identifying the environmental conditions favouring transitions to selfing and determining their population genetic consequences can provide insights into how often and why selfing evolves in heter... Heterostyly is an adaptation found in numerous families that enables outbreeding in dioecious flowers, complementing self-incompatibility mechanisms. However, an evolutionary transition to homostyly with high levels of self-fertilization is frequently seen, with consequences for the genetic structure, evolution and adaptation of the species. The...Read More
