Rapid and reversible root growth inhibition by TIR1 auxin signalling (Nature Plants)

Auxin mediates many of its effects through transcriptional changes via the well-known interaction between its co-receptors and transcriptional regulators (TIR1/AFB – Aux/IAA), but some auxin responses happen too quickly to be explained by transcriptional changes. Fendrych et al. demonstrate that root…

Of puzzles and pavements: a quantitative exploration of leaf epidermal cell shape (bioRxiv)

Arabidopsis plants have epidermal pavement cells (the cells that make up the bulk of the epidermis, other than guard cells or trichomes) that are often described as “jigsaw puzzle” shaped, and, because Arabidopsis is such a useful model organism, we have nice models for how these distinctive shapes…

Calcium-mediated ABA signaling negatively regulated by CBL-CIPK system in guard cells (Plant Physiol.)

Abscisic acid (ABA) plays a critical role in the opening and closing of the stomatal pore. This stomatal movement is essential for homeostasis, photosynthesis and stress responses. An influx of calcium ions and an increase the cytoplasmic calcium concentration of the guard cells are an early event in…

Review: Models and mechanisms of stomatal mechanics ($) (TIPS)

Guard cells are undoubtedly fascinating and frequently reviewed in terms of both their developmental programming and the intracellular signals that contribute to their function. This review, by Woolfenden, Baillie et al., covers a less familiar topic, that of the biophysical constraints to the mechanics…

What We're Reading: July 6th

Review: Plasmodesmata- form and function ($) Plasmodesmata are cell-cell junctions forming cytosolic bridges between neighbouring plant cells that provide an essential avenue for intercellular communication during a multitude of developmental and stress-related responses throughout the plant kingdom.…

The Phytophthora RXLR effector AVR3a12 suppresses ER-mediated plant immunity (Mol. Plant)

The pathogenic oomycete Phytophthora capsici secretes RXLR effector proteins into plant cells to subvert host cell machinery and facilitate disease. Several RXLR effector proteins have been characterized to date, however, Phytophthora species encode a vast array of effector molecules that likely target…

Summer fun: how plants beat the heat

By Adam Phillips. Reprinted from It Ain't Magic, The RIKEN Global Communications Team https://itaintmagic.riken.jp/hot-off-the-press/plants-beat-heat It seems like I’ve been writing a lot about plants recently. The truth is that I hardly have enough time to write about all the cool plant…

Chen Mingsheng's research team found an evolutionary trend of genes fleeing the centromere region

Article source: http://theworldseeds.cn/index.php?p=152804 (Translated by Google Translate) The centromere and its surroundings are the fastest-evolving and most complex areas of the plant genome. The centromere and near centromere regions not only undergo rapid sequence changes and structural remodeling,…
