A DNA Methylation Reader with an Affinity for Salt Stress
Blog, Research, The Plant Cell, The Plant Cell: In BriefHigh levels of soil salinity lead to toxic accumulation of sodium (Na+) and chloride (Cl-) ions in plants, which adversely affect plant growth and yield. Plants use several strategies to cope with salt stress. These include removal and compartmentalization of toxic ions, and maintenance of growth and…

Tomatoes turn pale in the heat: high temperature reduces red and green pigmentation via phytochromes
Blog, Plant Physiology, Plant Physiology: News and Views, ResearchThe gardeners among us know that direct sunlight is a prerequisite to obtain full-sized, bright red tomato (Solanum lycopersicum) fruits. Indeed, light increases the accumulation of yellow and red carotenoid pigments, particularly lycopene, in ripe tomato fruits while it also boosts chlorophyll levels…
Hydration-dependent phase separation of a prion-like protein regulates seed germination during water stress (bioRxiv)
Plant Science Research WeeklyPlant seeds can remain dormant for several years under stress conditions and subsequently germinate once favorable conditions return. Even though this phenomenon has been known for many years, what keeps the seed from germinating during the unfavorable conditions, especially during water deficit conditions,…
Feasting While Fasting: How Autophagy Helps Maize Survive Carbon Starvation
Blog, Research, The Plant Cell, The Plant Cell: In BriefMost macro-molecular components of plant cells (e.g., proteins, lipids, and even entire organelles) are subject to an ongoing process of recycling to both rejuvenate aging structures and optimize the allocation of cellular nutrients. A major recycling route is autophagy, which occurs under normal conditions…
