Desiccating leaves show increased ABA levels triggered by low turgor – right? Apparently not! The pressure chamber experiments showing increased ABA levels in desiccating leaves are inconsistent when the entire leaves are enclosed in the chamber. Sack et al. proposes that the turgor pressure is increased during the pressure chamber treatment, rather than decreased and […]

About Magdalena Julkowska
Magdalena is a PostDoc at King Abdullah University for Science and Technology (KAUST, Saudi Arabia) working with Prof. Mark Tester. Her main interests are (1) salt-induced changes in root-to-shoot ratio in Arabidopsis, (2) study the expression patterns in plants with enhanced sodium accumulation in their roots and (3) development of tools for data analysis based on R/Shiny. She is passionate about capturing plant architecture using simple models, understanding plant physiology and salinity tolerance.

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, followed by a reverse genetic screen, the team identified 116 ABA effector loci. The identified […]
Transposable elements are known to affect their neighboring genes, but they were so far unknown to affect the function of distant genes. Cho and Paszkowski observed a high level of transposon transcription expressed in rice. A transposon with root specific expression, MIKKI, was found to contain an imperfect binding site for miRNA171, which in turn […]
