About you Describe your journey from student to newly appointed faculty I was an undergraduate at William and Mary in Virginia and did an honors thesis with fruit flies in George Gilchrist’s lab. I spent two amazing summers as an NSF REU and then summer technician at Rocky Mountain Biological Lab in Colorado working with […]

About you Describe your journey from student to newly appointed faculty I did my undergraduate degree at the University of Leeds, then moved to the University of York to do my PhD with Ottoline Leyser. I really enjoyed my PhD, but decided I didn’t want to work on auxin any more (famous last words), so […]
About you Describe your journey from student to newly appointed faculty I started my undergraduate degree somewhat begrudgingly taking introductory biology at the University of Pennsylvania. Half of that introductory course was taught by Dr. Scott Poethig, a corn geneticist, whose lectures forced me to think about plants in a new light. I continued taking […]
Plants respond to a low phosphate environment through increased elongation of root hairs. Bhosale et al. showed that low external P increases levels of the auxin (IAA) in Arabidopsis roots through the TAA1 (TRYPTOPHAN AMINO TRANSFERASE 1)-mediated auxin biosynthesis pathway. At the same time, the auxin influx carrier AUX1 facilitates shootward auxin transport in low-P […]
The cytokinin-based response is assumed to be achieved through context-dependent transcriptional regulatory mechanisms. Potter et al. analyzed cytokinin-induced alterations in chromatin accessibility using ATAC-seq (Assay for Transposase-Accessible Chromatin using Sequencing) and combined these results with RNA-seq and chromatin immunoprecipitation (ChIP)-seq datasets. Their results suggest that differentially accessible regions are adjacent to cytokinin-regulated genes and mostly […]
Méndez-Bravo et al. explored the mechanism for the dramatic phenotype of the ctr1 mutant (CONSTITUTIVE TRIPLE RESPONSE 1), which inhibits both cell division and elongation. In the ctr1-1 mutant background, auxin response is induced at the root tip and an increase in expression of the auxin transporter PIN2 is observed. The authors also found a […]
Auxin distribution depends on the polar localization of PIN-FORMED or PIN proteins. Based on different development and environmental stimuli, PIN proteins switch polarity to redirect the auxin flux. Additionally, phosphorylation of PIN is required for its function. For instance, PIN3 phosphorylation is required for PIN3 polarization and hypocotyl gravitropic response. Grones et al. showed that […]
The plant trans-Golgi network (TGN) plays the role of early endosomes and acts as hub for the both secretory and vacuolar trafficking pathways. Two types of TGN, GA-TGN (Golgi-associated TGN) and GI-TGN (Golgi-released independent TGN), have been observed in plants. Here, Uemura et al. explore the cellular and physiological roles of GI-TGN. They show that […]
