Late blight, caused by the oomycete plant pathogen Phytophthora infestans, is a destructive disease that leads to significant yield loss in potatoes and tomatoes. The introgression of resistance (R) genes, which encode nucleotide-binding domain leucine-rich repeat-containing receptors (NLRs), into cultivated potatoes, highly effective controlling late blight. Here, we generated transgenic 2R 3R potato lines stacking R genes Rpi-blb2/Rpi-vnt1.1 Rpi-vnt1.1/RB/R8, respectively, susceptible cv. Desiree background. resulting plants showed virulent P. infestans field isolates. We hypothesized either resulted up-regulation broader range immune-related or, more importantly, increase fold change gene expression. To test our hypotheses, performed transcriptome analysis identified subset core are induced response carrying single versus stacks multiple genes. In analysis, not only induction defense-associated but also global expression change, pathogen. further demonstrated calcium-dependent protein kinase 16 (StCDPK16) significantly contributed strain, background, activity-dependent manner. Thus, data suggest enhances blight through modulating defense-related highlights CDPK16 as novel player gene-mediated resistance.

Drought stress is a common abiotic challenge that profoundly impacts plant growth and development. As sessile organisms, plants rely on various physiological morphological adaptations to cope with drought conditions. The CIPK (calcineurin B-like protein-interacting protein kinase) family proteins play pivotal role in mediating responses through modulation of cellular membrane events via the CBL-CIPK complex. However, reports documenting CIPKs' regulation non-membrane are scant. In this study, we discovered novel subcellular localisation pattern AtCIPK20 Arabidopsis, specifically cortical microtubules (cMT), which distinct from previously reported patterns CIPKs. regulates ABA-induced loss cMT organisation guard cells, thereby facilitating stomatal closure, mitigating leaf water loss, protecting Arabidopsis. C-terminal regulatory domain governs its targeting, whereas interaction CBL partners disrupts localisation. Notably, targeting characteristic not exclusive, as several other members maize, rice exhibit similar patterns. These findings broaden our current understanding resistance suggest future exploration molecular functions should adopt more comprehensive perspective.
