Panel of micrographs showing the efficacy of probe roGFP2-PRXIIB when targeted to cytosol, nuclei, mitochondria and chloroplasts to monitor H2O2 accumulation in real time in different subcellular compartments during immune activation, revealing different temporal patterns of H2O2 accumulation during pattern- and effector-triggered immune responses in different compartments.

This fascinating new #JIPB review by Iswanto et al. highlights work on #TranscriptionFactor engineering that has led to improvement in #growth performance, #yield and immunity, focusing on changes in #plant architecture related to improved yield and #disease resistance.

Egg cell and endosperm GFP micrographs of WT and mutant plants illustrate that FEMALE GAMETE MATURATION 1/PENTATRICOPEPTIDE REPEAT PROTEIN 4), a component of the mitochondrial ribosome large subunit, directly interacts with another mitochondrial protein GAMETE CELL DEFECTIVE 1 to play an essential role in maturation of the egg cell and central cell.

Let's play "Supervillain or #antifungal lipopeptides?"
Yuan et al. will go first...
...with a new study, showing that iturin and fengycin lipopeptides inhibit #pathogenic #Fusarium in #wheat, targeting components of the #cell membrane and more!

Drawing of a whole wheat plant with two insets describing how the antagonistic lipopeptides iturin and fengycin from Bacillus amyloliquefaciens S76-3 inhibit the growth of the pathogen Fusarium graminearum by binding to multiple components in the cell membrane of Fusarium cells and inducing cell swelling. Lipopeptides also activate systemic acquired resistance in wheat against Fusarium head blight and regulate wheat development.

Cover of the June 2025 issue (Volume 67, Issue 6) of the Journal of Integrative Plant Biology. The cover features a bright orange citrus fruit, cut in half transversely to reveal stylized representations of meiosis in each segment. White citrus flowers surround the fruit, and strands of DNA with notations indicating deletions run between the two halves. Cover designed by Yan-Jie Fan, Wen-Wu Guo and Xiao-Meng Wu.

Pollen hydration, germination, and tube growth are vital processes that involve complex signaling pathways. Here, Kim et al report that OsPRK1/2/3-mediated #ROS signaling is required for #pollen tube #germination in #rice

The rice pollen-specific receptor-like kinases OsPRK1, OsPRK2, and OsPRK3 play a crucial role in reactive oxygen species (ROS)-mediated pollen hydration and germination. This diagram illustrates how triple mutants display male sterility due to decreased ROS levels and impaired pollen hydration, and their germination phenotype can be partially restored by exogenous application of H2O2.
