Rice false smut caused by Ustilaginoidea virens is becoming one of the most recalcitrant rice diseases worldwide. However, molecular mechanisms underlying immunity against U. remain unknown. Using genetic, biochemical and disease resistance assays, we demonstrated that xb24 knockout lines generated in non-Xa21 background exhibit an enhanced susceptibility to fungal pathogens Magnaporthe oryzae. Consistently, flg22- chitin-induced oxidative burst expression pathogenesis-related genes were...
Rice false smut caused by Ustilaginoidea virens has become one of the most important rice diseases. U. specifically infects florets through stamen filaments. However, it is mysterious how inhibits floral immunity for successful colonization. Here, we show that a small cysteine-rich effector SCRE9 key virulence factor in virens. Expression not only suppresses immune responses and resistance, but also significantly increases expression expansin gibberellin (GA) biosynthetic genes GA content...
Abstract Plant immunity is fine-tuned to balance growth and defense. However, little yet known about molecular mechanisms underlying immune homeostasis in rice (Oryza sativa). In this study, we reveal that a calcium-dependent protein kinase (CDPK), OsCPK17, interacts with stabilizes the receptor-like cytoplasmic (RLCK) OsRLCK176, close homolog of Arabidopsis thaliana BOTRYTIS-INDUCED KINASE 1 (AtBIK1). Oxidative burst pathogenesis-related gene expression triggered by pathogen-associated...
Autotetraploid rice shows distinct morphological, physiological, hormonal, and gene expression changes that enhance its resistance to blast.
Whole-genome duplication is a significant evolutionary mechanism in plants, with polyploid plants often displaying larger organs and enhanced adaptability to unfavorable conditions compared their diploid counterparts. The cell wall acts as primary defense for plant cells against external stresses, playing an essential role the plant’s resistance various stressors. In this study, we utilized both autotetraploid its donor rice (Oryza sativa L.) analyze phenotypic differences comparatively,...
The necessity to understand plant adaptations environmental stressors is underscored by the role of polyploidy in species evolution. This study focuses on superior stress resistance exhibited autotetraploid rice, which arises from chromosome doubling, comparison its diploid donor. We provide a quantitative analysis that highlights differing susceptibilities (GFD-2X) and (GFD-4X) rice blast disease, with GFD-2X being significantly more susceptible. Our investigation centers transcription...
