Linking turgor with ABA biosynthesis: implications for stomatal responses to vapour pressure deficit across land plants

SAM McAdam, TJ Brodribb (2016) Linking turgor with ABA biosynthesis: implications for stomatal responses to vapour pressure deficit across land plants. Plant physiology, DOI:10.1104/pp.16.00380

Stomatal responses to changes in vapour pressure deficit (VPD) constitute the predominant form of daytime gas exchange regulation in plants. Stomatal closure in response to increased VPD is driven by the rapid up-regulation of foliar ABA biosynthesis and…

Evidence that chlorinated auxin is restricted to the Fabaceae but not to the Fabeae

HK Lam, SAM McAdam, EL McAdam, and JJ Ross. Evidence That Chlorinated Auxin Is Restricted to the Fabaceae But Not to the Fabeae. Plant Physiol. 2015 168: 798-803. doi:10.1104/pp.15.00410

Auxin is a pivotal plant hormone, usually occurring in the form of indole-3-acetic acid (IAA). However, in maturing pea (Pisum sativum) seeds, the level of the chlorinated auxin, 4-chloroindole-3-acetic acid (4-Cl-IAA), greatly exceeds that of IAA. A key…
