The bZIP Transcription Factor UvbZIP14 Regulates Vegetative Growth, Conidiation and Abiotic Stress Tolerance in Ustilaginoidea virens
bZIP transcription factors play a crucial role in regulating various physiological processes in phytopathogens. Ustilaginoidea virens is known to possess 28 bZIP transcription factors; however, their biological functions remain unexplored. In this study, the function of UvbZIP14 in U. virens was investigated. The expression levels of UvbZIP14 were found to be up-regulated after rice inoculation with U. virens. The knockout mutants and complemented strains of UvbZIP14 were generated and characterised. The knockout mutants display increased growth and decreased conidiation. Compared with the wild-type strain, the knockout mutants exhibit reduced sensitivity to NaCl and sorbitol but increased sensitivity to CFW. There was no significant difference in the number of false smut balls in rice between the knockout and wild-type strains. These results findings highlight the significant role of UvbZIP14 in regulating vegetative growth, conidiation and tolerance to abiotic stress in U. virens.
期刊介绍:
Journal of Phytopathology publishes original and review articles on all scientific aspects of applied phytopathology in agricultural and horticultural crops. Preference is given to contributions improving our understanding of the biotic and abiotic determinants of plant diseases, including epidemics and damage potential, as a basis for innovative disease management, modelling and forecasting. This includes practical aspects and the development of methods for disease diagnosis as well as infection bioassays.
Studies at the population, organism, physiological, biochemical and molecular genetic level are welcome. The journal scope comprises the pathology and epidemiology of plant diseases caused by microbial pathogens, viruses and nematodes.
Accepted papers should advance our conceptual knowledge of plant diseases, rather than presenting descriptive or screening data unrelated to phytopathological mechanisms or functions. Results from unrepeated experimental conditions or data with no or inappropriate statistical processing will not be considered. Authors are encouraged to look at past issues to ensure adherence to the standards of the journal.
