The small-molecule pifithrin-α deactivates ETR1 to repress shade avoidance in Arabidopsis
Compound PFT-α inhibits shade-induced hypocotyl elongation by mimicking ethylene to inactivate ETR1 and down-regulate PIFs level.

Xiao et al. tested the role of genome size in adaptation in 53 Alpine ginger herb populations, finding that genome size has undergone adaptive evolution driven by environmental stress; smaller genomes are advantageous in changing alpine habitats

An individual of Roscoea tibetica from Shangri-La, located in the mountains of Southwest China. The image in the top right corner illustrates the substantial alterations in the relationship between genome size and stomatal size when transitioning from wild conditions to a common garden environment. Similarly, the image in the lower left corner demonstrates the significant changes in the relationship between stomatal size and stomatal density under the same conditions.

Here’s an interesting new paper on ROS1, an enzyme that removes DNA methylation and that is POSITIVELY controlled by DNA methylation.
It’s repression during heat stress 🥵🌱 is crucial to suppress transposon mobility! 🧬

Plants repress ROS1 expression to attenuate heat-induced transposon burst - Nature Plants
Plants suppress the DNA demethylase ROS1 under heat stress to limit transposon activation, preventing genome instability. This conserved mechanism balances stress adaptation with genome protection.

Plants "bleed" too, but through gases!
When wounded, ethylene leaks out and oxygen seeps in. This gas shift acts as an alarm, triggering self-repair to seal the breach. Excited to share our new collaborative work uncovering this clever plant mechanism! Excellent summary here, indulge!

Most staple food crops are expected to experience substantial production losses due to climate change, even when mitigation measures to limit the impact of climate change are considered, according to a study in Nature. The study finds that only rice might avoid substantial losses. 🧪
Impacts of climate change on global agriculture accounting for adaptation - Nature
Analysis of data on six stable crops, capturing two-thirds of global crop calories, allows estimation of agricultural impacts and the potential of global producer adaptations to reduce output losses owing to climate change.
