Hormonal changes...🌽

Dao et al have quantified #GibberellicAcid and #Auxin responses across multiple #maize #barley #sorghum & #wheat tissues/genotypes, identifying common cereal responsive genes & reliable biosensors for use in future studies

#Phytohormones

Figure 1 from Dao et al. 2025, consisting of four figures showing that GPS2 transient expression reveals genotype and tissue differences in FRET ratio after GA treatment. (Panel a) Confocal section showing transient expression of GPS2 after biolistic bombardment, which yields characteristic nuclear signal of CFP (left), CFP to AFP FRET ex/em (middle), and AFP ex/em (right). (panel b) Fluorescence quantification based on mask multiplication between binarized channels allows identification of GPS2-expressing regions of interests (ROIs) and calculation of FRET/CFP emission ratio. (Panel c) Box plots showing leaf tissues transiently expressing GPS2 in maize, barley, sorghum, and wheat display a FRET/CFP emission ratio response when treated with increasing levels of GA. Note that maize d1, GA biosynthesis mutant, displays a decrease in FRET ratio. (Panel d) Box plots showing floral tissues transiently expressing GFP2 in maize and barley responding to GA, with maize only responding after high GA treatments (10 uM and 100 uM).

Switch it Up...

Kubushiro et al. delve deeper into the process of chromatic acclimation in #cyanobacteria & show that rod-shaped photosynthetic supercomplex phycobilisomes in Synechocystis sp.PCC 6803 undergo incomplete photoswitching, likely due to adaptation

For explanatory purposes, the amounts of PSII and hemidiscoidal PBS are shown as equal between all light conditions: Green (top), Red (middle) and Far Red (bottom).

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

Open Access: doi.org/10.1093/pcp/...
#PlantScience
#Stomata

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.
