To avoid ammonium toxicity, the ammonium transporters (AMTs) are tightly regulated by phosphorylation-dependent inactivation. The multifunctional kinase CIPK23 inactivates the AMT1s by phosphorylating conserved threonine residues (T460 in AMT1;1 and T472 in AMT1;2).  ABA-INSENSITIVE1 (ABI1) and ABI2…

Proper development requires an aging program that is regulated throughout the entire lifespan of an organism as well as across generations. In plants, reproductive cells are derived from differentiated cells, and thus the aging program encoded in these reproductive cells must be rejuvenated per generation.…

Climate emergency and the increase of human population are challenges for human food security. Plant breeders use natural genetic variation to improve crops, but bread wheat (Triticum aestivum L.) has particularly low genetic diversity with unique evolutionary constraints. Genetic modification of spike…

To better understand plant responses to different environments, Lou et al. compared Arabidopsis thaliana accessions derived from Sichuan (high precipitation/regular flooding) and Tibet (arid) to isolate genetic adaptations towards flooding stress. The two accessions showed divergent phenotypes: the Sichuan…

Are modern agricultural practices good for the environment? Or at least for the crops? If we look at a small field at a particular time point, it may seem they are good. But looking at a broader picture gives a different notion. In a recent study, Edlinger et al. collected 210 soil samples from traditional…

The observation that “Those who cannot remember the past are condemned to repeat it,” (attributed to philosopher George Santayana) is quite relevant for our efforts to comprehend the impacts of climate change. As we observe temperature and rainfall records being broken with increasing frequency,…

A robust mechanism for resetting juvenility during each generation in Arabidopsis Proper development requires an aging program that is regulated throughout the entire lifespan of an organism as well as across generations. In plants, reproductive cells are derived from differentiated cells, and thus…
