Astaxanthin is the reddish carotenoid pigment that gives color to shrimp, salmon, and flamingo. However, these animals…
Tomatoes turn pale in the heat: high temperature reduces red and green pigmentation via phytochromes
The 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 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
Most 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…
Cold, but not freezing: the ICE-L genome ($) (Current Biology)
When sea water freezes, it forms not a solid mass of ice, but rather a frozen matrix criss-crossed by tiny brine-filled channels. It is within these brine channels in the Antarctic sea ice that the psychrophilic (cold-loving) green alga ICE-L lives. How is it able to thrive in such a seemingly hostile…
