Sense and Sensibility...

Takahashi, @natiwongpan.bsky.social et al. discuss recent genetic studies identifying key signalling molecules that underpin CO2 sensing by #stomata; such findings could help improve water use efficiency in plants

Figure 2 from the review by Takahashi et al. showing schematic diagram explaining CO2 sensing and signal transduction in stomatal guard cells. Top panel (A) shows a schematic model of the early receptor/sensor signal transduction mechanisms under low/high levels of CO2 and ABA conditions. Bottom panel (B) shows the dominant mutations of HT1 (A109V and R102K) that impair CO2 sensing by disrupting MPK4/12 binding, which can activate CBC1 and cause CO2-insensitive constitutive open stomata in dominant mutant plants. These HT1 mutations may have a similar effect to the well-known ABA-insensitive PP2C mutations, abi1-1 and abi2-1, which disrupt ABA-dependent binding to PYL/RCARs thereby impeding inhibition of their phosphatase activity, resulting in open stomata and strong ABA-insensitivity.

I received an Alstrosmeria award in plant biology at the annual retreat for UCSD School of Biological Sciences. Thanks my mentor, lab members, and collaborators for their supports.

Our review paper on stomatal CO2 signaling in PCP is now online. It 's my very first time contributing to a review paper. What a great experience!! doi.org/10.1093/pcp/pcaf074
Stomatal CO2 Sensing in Plants: Control of Gas Exchange and Interactions with Environmental Stimuli
Abstract. Stomatal pores in land plants rapidly and reversibly open and close in response to diurnal changes in leaf carbon dioxide (CO2) concentration. St

📣 Thermomorphogenesis community 📣
Next week, Nattiwong Pankasem presents his paper on stomatal opening in warm and higher temperatures.
Hope to see many of you there!!
