Personal Trainer: bHLH121 Functions Upstream of a Transcriptional Network of Heavy Lifters Involved in Balancing Iron Levels
Research, The Plant Cell, The Plant Cell: In BriefIron is a cofactor of numerous plant proteins that function in processes ranging from redox reactions during photosynthesis to respiration. Typical soils contain approximately 1–5% iron, but much of this iron is not readily accessible to plants due to low solubility. Nongraminaceous plants help solubilize…

Review. Diatom molecular research comes of age: Model species for studying phytoplankton biology and diversity (Plant Cell)
Plant Science Research WeeklyDiatoms are photosynthetic eukaryotes and contribute substantially to global carbon fixation. They are distantly related to green plants, having shared the same primary endosymbiotic event, although they subsequently underwent additional secondary endosymbioses. There are over 100,000 species of diatoms,…
Review: Role of blue and red light in stomatal dynamic behaviour (J Exp Bot)
Plant Science Research WeeklyGuard cells are extremely sensitive and dynamic, and their behaviour controls rates of gas exchange and transpiration, which affect evaporative cooling and transport in the xylem. Matthews et al. review the roles of light signalling pathways in guard cell responses. Cues that control guard cell ion channels…
Combinatorial interactions of the LEC1 transcription factor specify diverse developmental programs during soybean seed development (PNAS) ($)
Plant Science Research WeeklyLEC1 (LEAFY COTYLEDON 1) transcriptional factor regulates multiple developmental processes during different stages of seed development including macromolecule accumulation, inhibition of germination and morphogenesis. In this paper Jo et al., have uncovered the mechanism of LEC1 functioning with other…
The Arabidopsis receptor kinase IRK is polarized and represses specific cell division (Devel. Cell) ($)
Plant Science Research WeeklyOrientation of cell division decides daughter cell fate and is fundamentally important for tissue patterning and morphology. For instance, asymmetric cell division leads to the generation of new cell types; in contrast, symmetric division produces cells with similar identity in a proliferative manner.…
Promotion of BR biosynthesis by miR444 is required for ammonium-triggered inhibition of root growth (Plant Physiol.) ($)
Plant Science Research WeeklyNitrogen, as one of the most important plant nutrients, profoundly affects root growth. Nitrogen is usually taken up in one of two forms, nitrate (NO3-) or ammonium (NH4+), and the two forms affect root growth differently. Here, Jiao et al. demonstrate a connection between ammonium, a small RNA, and…
