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).

Diagram describing how Clade A protein phosphatases of type 2C PP2Cs dephosphorylate B3 RAF kinases at a conserved serine residue critical for ATP binding, thereby maintaining their basal activity. Under stress, RAFs rapidly autophosphorylate this residue for autoinhibition. This mechanism ensures the precise timing and dynamics of SnRK2 activation during plant stress responses.

Diagram representing a cross-section through the plasma membrane and cytosol to illustrate how the scaffolding protein RACK1 is involved in polar auxin transport and signaling, binding to PINOID and PIN-FORMED2, enhancing their interaction and phosphorylation-dependent auxin efflux. Knocking down RACK1 genes impairs auxin-related processes such as root growth and gravitropic response.

Diagram of a whole tomato plant, flanked by contrasting flow diagrams for low K+-sensitive tomato and low-K+ tolerant tomatoes, illustrating that, in tomato, jasmonate activates a SlJAZ2/3—SlMYC3-like transcription factor module that regulates inhibition of plant growth induced by potassium ion (K+) deficiency and K+ uptake by regulating genes encoding K+ transporters and ion channels. Plus, it's noted that SlMYC3-like promoted SlJAZ2/3 expression, forming a negative feedback circuit in jasmonate signaling, mediating K+ uptake.
Wang et al. explore the role of the jasmonic acid–SlJAZ2/3–SlMYC3-like module in K+ uptake and #plant #growth in #tomato under low K+ stress, providing key insights into the regulation of plant growth and K+ uptake.

Model showing the two distinct response zones. F. oxysporum infects an A. thaliana root tip via the meristematic zone, where it colonizes the vasculature (purple cells=colonized zone). The tissue around this zone undergoes immediate programmed cell death (dark gray cells). As the colonization front (light purple line) progresses in the vasculature, so does a cell death front (black line) across all tissues. In an attempt to prevent the fungus from infecting more tissue and spreading through the vasculature to all parts of the plant, the plant triggers the HR in a small, spatially confined group of cells immediately adjacent to the colonization front (yellow cells), the HR zone. HR is activated by SA in combination with ET, ROS, and DAMP signaling. Slightly removed from the HR and colonized zones, the plant launches a second line of defense to combat the spread of the pathogen in the defense response zone (orange cells). This response is dependent on WRKY11 and JA/ET biosynthesis and signaling. JA and SA are mutually antagonistic, thereby establishing the two spatially separate zones of distinct action. WRKY11 is furthermore a negative regulator of basal resistance. Upon colonization by F. oxysporum, the plant therefore represses WRKY11 in all tissues other than the vasculature, therefore releasing basal resistance genes in these tissues from repression and allowing these cells to activate basal immunity in the case of spread of the infection. Long-distance signaling via the PEP pathway further contributes to this.

This work was completed @mpipz.bsky.social with @horizoneu.bsky.social funding.
Three petri dishes with Arabidopsis seedlings. In the plate labeled "Control", the seedlings stand upright. In the plate labeled "EBL", a brassinosteroid phytohormones, the plants are all flat on the surface. On the last dish, labeled "BRZ", an inhibitor or Brassinosteroids, they are short, but most stand up again.
But at least we got a short paper on #PlantCellWalls, #PlantGravitropism and #Phytohormones out in @plantcellphysiol.bsky.social.
