A Lipid Synthesis Enzyme Confers Freezing Tolerance

Despite major advances in understanding cold signaling, cold acclimation, and freezing protection in model and crop species, and extensive studies of natural variation in freezing tolerance in Arabidopsis accessions, the question of which genes and mechanisms underlie freezing tolerance of wild species…

Review. Out of shape during stress: a key role for auxin

The plant hormone auxin is a major player in determining root growth and architecture, but we are just starting to understand how auxin distribution is altered by abiotic stresses. Kover et al. discuss how the “upside-down fountain” of auxin in the root is affected by abiotic stress conditions. Auxin…

Phosphate Translocation from Roots to Shoots is Precisely Modulated

Ye et al. discover a protein that mediates phosphate translocation and is dependent on environmental phosphate supply. Plant Cell (2018). https://doi.org/10.1105/tpc.17.00845 By Qing Ye and Yi-Fang Chen Background: Phosphorus is a major essential nutrient for plant growth and development, and phosphate…

Protein Editing for Multi-Tasking

Zauner et al. investigate the mechanism of protein re-purposing. The Plant Cell (2018). https://doi.org/10.1105/tpc.17.00963. By Florian B. Zauner, Elfriede Dall and Hans Brandstetter Background: Plants cannot run away from herbivores, drought, or heat. To withstand adverse conditions, plants have…

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…

Diacylglycerol acyltransferase 1 contributes to freezing tolerance

Low temperature is one of the environmental factors limiting the plant distribution. Yet there are some plants that can survive freezing temperatures, such as Boechera stricta, native to the Rocky Mountains, spread across a broad range of elevations. Arisz and colleagues observed that freezing tolerance…

The demise of the largest and oldest African baobabs ($)

Patrut et al. report that 8 of the 13 oldest and 5 of the 6 largest African Baobab (Adansonia digitata L.) trees, known for their enormous size and great longevity, have died (or at least their largest and/or oldest parts/stems have collapsed and died). Included in the dead are Panke, the oldest Baobab…

Alternative Splicing Plays a Major Role in Plant Response to Cold Temperatures

Plants in temperate regions experience near-freezing temperatures that allow them to develop a cold response prior to freezing. This cold acclimation process involves changes to chromatin structure, transcription, RNA processing, translation, post-translational modifications and protein stability. Genome-wide…

Regulatory Divergence in the Stress Response of Tomato

Humans have domesticated crops for thousand of years by artificially selecting plants for numerous traits including morphology, lower toxicity or higher yield. As a result, plant domestication often altered plant fitness and resistance to stress under controlled conditions (Meyer & Purugganan 2013).…
