They are signal molecules produced within the plant functioning in extremely low concentrations. The acid growth theory states that the auxin-induced acidification of plant cell walls causes their ...

Previous research has indicated that LR development is controlled by many extrinsic (environment and nutrition) and intrinsic signals (hormones and signaling molecules ... Plant hormones, including ...

Scientists studying samples that NASA collected from the asteroid Bennu found a wide assortment of organic molecules that shed light on how life arose. By Carl Zimmer Our solar system contains ...

These include amino acids, which are the molecules that make up proteins, as well as nucleobases - the fundamental components of DNA. This doesn't mean there was ever life on Bennu, but it ...

A new tool could make it easier to study scarce plant molecules. Researchers have developed so-called microbial cell factories -- using E. coli and yeast -- to produce a special class of plant ...

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 ...

In higher plants, auxin biosynthesis is likely extremely complex in plants ... the external stimuli will activate the cell membrane-located receptor molecules and initiate the changes of conformation ...
