Several thaumatin-like proteins bind to beta-1,3-glucans.
Pathogenesis-related proteins from intercellular fluid washings of stressed barley (Hordeum vulgare L.) leaves were analyzed to determine their binding to various water-insoluble polysaccharides. Three proteins (19, 16, and 15 kD) bound specifically to several water-insoluble beta-1,3-glucans. Binding of the barley proteins to pachyman occurred quickly at 22 degreesC at pH 5.0, even in the pres...
متن کاملStructure of Haze Forming Proteins in White Wines: Vitis vinifera Thaumatin-Like Proteins
Grape thaumatin-like proteins (TLPs) play roles in plant-pathogen interactions and can cause protein haze in white wine unless removed prior to bottling. Different isoforms of TLPs have different hazing potential and aggregation behavior. Here we present the elucidation of the molecular structures of three grape TLPs that display different hazing potential. The three TLPs have very similar stru...
متن کاملArabidopsis SEPALLATA proteins differ in cooperative DNA-binding during the formation of floral quartet-like complexes
The SEPALLATA (SEP) genes of Arabidopsis thaliana encode MADS-domain transcription factors that specify the identity of all floral organs. The four Arabidopsis SEP genes function in a largely yet not completely redundant manner. Here, we analysed interactions of the SEP proteins with DNA. All of the proteins were capable of forming tetrameric quartet-like complexes on DNA fragments carrying two...
متن کاملChanges of edogenous hormone levels during short-day inductive floral initiation and inflorescence differentiation of Chrysanthemum morifolium ‘Jingyun’
Duration of various stages of inflorescence differentiation and hormone levels in apical buds eventually decide the harvest time, flower uniformity and quality of ornamental plants. The progress in inflorescence differentiation process in the chrysanthemum cultivar ‘Jingyun’ can be divided into nine stages. Following short day induction, it took 4d to reach the growing point hypertrophy stage, ...
متن کاملFT-like proteins induce transposon silencing in the shoot apex during floral induction in rice.
Floral induction is a crucial developmental step in higher plants. Florigen, a mobile floral activator that is synthesized in the leaf and transported to the shoot apex, was recently identified as a protein encoded by FLOWERING LOCUS T (FT) and its orthologs; the rice florigen is Heading date 3a (Hd3a) protein. The 14-3-3 proteins mediate the interaction of Hd3a with the transcription factor Os...
