Natural variation identified genes affecting drought-induced abscisic acid accumulation in Arabidopsis thaliana ($)

Dissecting the genetic controls of ABA is challenging, granted the complex modulation of ABA turnover and redundancy of the hormone perception machinery. In the recent study, Kalladan and colleagues explored natural variation of low-water-potential induced ABA accumulation. Using heuristic GWAS,…

In vivo gibberellin gradients visualized in rapidly elongating tissues

Biosensors can reveal cellular or even sub-cellular distributions of hormones, greatly enhancing our understanding of hormone action. Rizza et al. have developed an in vivo, FRET-based gibberellin biosensor, GIBBERELLIN PERCEPTION SENSOR 1 (GPS1), that incorporates portions of two GA-binding proteins,…

The effect of bisphenol A on growth, pigment composition and photosystem II activity of Arabidopsis thaliana

Many of the plastic consumables we have at home contain synthetic chemical BPA (Bisphenol A). In 1930, a UK scientist discovered that BPA weakly mimics the human hormone estrogen. It has also been found that tiny amount of BPA can leach out of plastic (Stanford University). Thus, there has been a heightened…
