Many plant species or genera living in the temperate forests of East Asia now have fragmented distributions closely linked to past climate oscillation. Repeated forest fragmentation can not only lead to allopatric divergence of species, but also give rise to speciation. Many biological factors, such as hybridization and polyploidization are also considered playan important role in these speciat...
Arbuscular mycorrhizal fungi (AMF), from the phylum of Glomeromycotais, is the most common mycorrhizal association between soil fungi and terrestrial plants, with about 75% of plants forming mycorrhizal symbioses with AMF.
Economically, Leguminosae is second in importance only to Poaceae. Legumes are the most valuable plant protein sources in human diet, and even the only protein sources in some poor regions of the world.
The communesins share an identical synthetically challenging heptacyclic core arrayed with two aminal groups and at least five stereogenic centers, including two vicinal quaternary carbons. This combination of intriguing structural complexity and interesting biological activities renders these alkaloids popular synthetic targets.
Phylogenomics applies genomic data to reconstruct the evolutionary history of organisms and has been applied to tackle rapidly radiating clades and hybridization events in diverse lineages.
The evolutionary pathway from outcrossing to high levels of self-fertilization has been followed in numerous taxa of herbaceous flowering plants.
Chinese scientist discovered new bioactive chemical compositions from coffee. In recent years, Yunnan became one of cultivation base of Coffea arabica in the world. Coffee Plantation in Yunnan accounted for 99% of China.
The scale of mining activities today is greater than ever but so are its environmental and social impacts. Over the past few decades mining has contributed to millions of hectares of land degradation worldwide. Open-pit mining transforms productive landscapes into ruined wastelands with disastrous consequences for biodiversity, climate, water and soil resources and the livelihoods and health of...
Variation in fruit production can influence the interactions betweeen plants and fruit predators and therefore affect population dynamics of both.
