- This all started with a classic “hey, that’s funny” observation by Jasper early in his PhD, when he found that in response to salinity in Arabidopsis roots, a specific cluster of up-regulated genes showed an opposite response to Na+-containing salts compared to osmotic stress and …. ABA.
- www.biorxiv.org/content/10.1... Our latest pre-print by Jasper Lamers et al. We discovered that both sodium-specific gene expression and specific phenotypic responses of roots to salinity can only happen due to a delayed ABA response, induced by the osmotic component of the salinity stress.
