为解决生长素双相效应及光影响其作用机制不明的问题，西南大学研究人员开展下胚轴生长响应研究。结果发现质外体 pH 是关键，光照与生长素拮抗调控其生长。此研究为植物生长调控提供新视角，强烈推荐科研读者阅读。

The acid growth theory states that the auxin-induced acidification of plant cell walls causes their expansion. A model now suggests that excessive acidification leads to growth inhibition ...

"Finding ways to tackle food insecurity is vital." Scientists discover potential solution for $30 billion food crisis: 'Designing systems to ... improve crop yields' first appeared on The Cool Down.

A study has identified key genetic pathways in corn that help its roots branch out to find water in soil; the varieties adapted to temperate regions like the U.S. corn belt showed large differences in ...

The researchers found through genetic analyses that two plant hormones, auxin and ethylene, play a role in how corn roots respond to water. While auxin was already known to help control this ...

The whole experiment was performed in duplicate. Besides physical parameters, biochemical contents, e.g., auxin, protein, alkaloids, terpenoids, and steroid contents were also measured. A paste of ...

Moreover, phytohormones, particularly auxin, act as internal regulators of root development in soil, starting from the early organogenesis to the formation of root hair (RH) through diverse signaling ...

The key phytohormone auxin is involved in practically every aspect of plant growth and development. Auxin regulates these processes by controlling gene expression through functionally distinct AUXIN ...

Here, we describe the auxin-inducible gene expression system (AGES). AGES relies on the auxin-dependent degradation of a ubiquitously expressed GAL80, and therefore, is compatible with existing ...
