Protein sorting in the secretory pathway is essential for cellular compartmentalization and homeostasis in eukaryotic cells. The endoplasmic reticulum (ER) is the biosynthetic and folding factory of secretory cargo proteins. The cargo transport from the ER to the Golgi is highly selective, but the molecular mechanism for the sorting specificity is unclear.
As a part of the global biodiversity hotspots, the Taita Hills forests, located in Taita Taveta County in southeastern Kenya, forms the northernmost tip of the Eastern Arc Mountains. They are highly fragmented forests embedded in a human settlements and farms on the slopes and hilltops, resulting in the loss of 98% of the original forest cover on those mountains. Despite several botanical explorations and extensive floristic studies in these mountainous areas, there is a clear lack of sufficient literature on the flora and vegetation of the area. Through a joint effort, several field expeditions were carried out between 2015 and 2019, with an effort put to expand geographical coverage to areas where plant collections were previously scarce.
Angiosperms may be distinguished from their gymnosperm peers by their flowers, and thus a flower is a good proxy of fossil angiosperms. However, flowers and their parts are usually too frail to be preserved in the fossil, which makes the origin of angiosperms and their flowers the foci of controversy. Recently, researchers reported a fossil flower bud, Florigerminis jurassica gen. et sp. nov., from the Jurassic in Inner Mongolia, China. This is the earliest fossil record of flower buds in the world so far.
The world is warming quickly with no indication of slowing down. This could be catastrophic for the production of food crops, particularly in already warm areas.
As forests age, differences in species functional traits become more important and reliable in predicting forest productivity, according to an international study.
Italian ryegrass (Lolium multiflorum) is a widely cultivated forage with excellent quality, high yield, good palatability and rich nutritional value. However, its growth is inhibited by salt tress, which is a major growth limiting factor.
Researchers have revealed the response mechanism of rhizosphere microorganisms of deep-rooted leguminous plant to water and nitrogen changes in desert ecosystem.
Researchers have revealed a potential mechanism of phosphorus acquisition by plants during succession of subtropical forests, according to a study recently published.
Most legume species have compound leaves with multiple joined units termed leaflets, and the geometry of leaflets (the spatial structure and organization of leaflets) largely determines the compound leaf shape, which has been broadly recognized in model compound-leafed species.
A plant used in traditional Chinese medicine has evolved to become less visible to humans, new research shows. Scientists found that Fritillaria delavayi plants, which live on rocky slopes of China’s Hengduan mountains, match their backgrounds most closely in areas where they are heavily harvested.
