Abstract:
Abstract Brassinosteroids (BRs), a group of plant steroid hormones, participate in the regulation of plant growth and developmental processes. BR functions through the BES1/BZR1 family of transcription factors, however, the regulation of the BES1 activity by post-translational modifications remains largely unknown. Here, we present evidence that the SUMO E3 ligase SIZ1 negatively regulates BR signaling pathway. T-DNA insertion mutant siz1-2 shows BL (Brassinolide, the most active BR) hypersensitivity and BRZ (Brassinazole, a BR biosynthesis inhibitor) insensitivity during hypocotyl elongation.

Abstract:
BRs (Brassinosteroids) regulate many essential pathways related to growth, cell elongation, cell expansion, plant architecture, and fruit development. The potential exogenous application of BR-derivatives has been proven to stimulate plant growth and development, including quality attributes of fruits, whereas its biosynthesis inhibition has shown the opposite effect. In this study, BR-insensitive tomato mutants were used to reveal the potential function of BR signaling in the regulation of fruit development to elaborate the regulatory mechanism of BR signaling in tomato fruits.

The fungicide Pristine, a commercial mixture of pyraclostrobin and boscalid, has been used widely on watermelon and other cucurbits to control gummy stem blight, caused by the fungus Didymella bryoniae. Since 2007, isolates of D. bryoniae insensitive to boscalid have been found in Georgia, Indiana, and South Carolina. Most isolates of D. bryoniae obtained in 2009 and 2010 from diseased watermelon leaves collected in several counties in Florida and North Carolina were found to be insensitive to boscalid using in vitro assays.
