The KEY🔑 to regulating Rubisco phase separation in the Chlamydomonas algal pyrenoid. Beautiful work by Shan He, @mjonikas.bsky.social, and friends. #PhaseSeparation #CO2 #PlantScience 🧪 🧶🧬 🌾 🌍

Algal pyrenoids—condensates that mediate ~1/3 of Earth’s CO2 fixation—change size and number as cells divide. Our data suggest a simple control mechanism: a kinase that continuously ejects material from the condensate! ☀️🌍🔬💧 #Biophysics #Photosynthesis

Pleased to see our perspective on the C3 model of photosynthesis published. It was fun revisiting the science behind it.

“The work of Professor Robson and his colleagues was 46 years in the making. Yet their fundamental research has enormous applications, from harvesting water from the air to drug delivery and even carbon dioxide removal from the atmosphere”, said Prof Chennupati Jagadish AC, President of the Academy.

🫛 SPECIAL ISSUE REVIEW 🫛

Meilhoc et al. ✍️

This review aims to provide answers to the oxygen paradox in nitrogen-fixing symbiosis and to highlight the dual roles of hemoglobins and ROS in nodule development, functioning, and senescence.

🔗 doi.org/10.1093/jxb/...

#PlantScience 🧪

Fig. 1.Schematic representation of oxygen trapping and energy metabolism within N2-fixing nodules. In infected cells, O2 is trapped by the Lbs (1), which release it near the mitochondria distributed around the cell periphery. O2-dependent mitochondrial respiration ensures the production of ATP (2). When the O2 concentration is too low, Pgb-NO respiration (3), involving nitrate reductase (NR) and phytoglobins (Pgb1, Lbs), gradually takes over and helps to regenerate ATP. In microoxic bacteroids, ATP is produced by the respiratory chain (4), which includes cbb3 oxidases with a high affinity for O2, and the denitrification pathway (5), which reduces nitrate (NO3–) to nitrogen (N2). Any traces of O2 that might inhibit nitrogenase are eliminated by Hmp-type hemoproteins (6) which, in the presence of NO, detoxify it to NO3–. Dashed lines represent the outer membranes of mitochondria and bacteroids. See full paper for abbreviations.

C4 plants respond to phosphate starvation differently than C3 plants

C4 photosynthetic plants accumulate phosphate preferentially in the leaves and respond more strongly to phosphate deficiency than C3 plants.
