Pollination drops as dynamic apoplastic secretions

摘要: Abstract Pollination drops are apoplastic secretions that involved in gymnosperm reproduction. Much of the research on pollination has been concerned with morphological and phenological descriptions drop. Composition analysis limited by phenology small volume Improved proteomics techniques have enabled a more comprehensive drop composition. It is emerging biochemically complex. Many components found other secretions, such as cell wall proteome, reproductive angiosperms, floral extrafloral nectar. In these liquids, proteins confer variety functions. this review, relevant reviewed an aim to develop model dynamic function. Comparing reveals similarities suggest may facilitate pollen–ovule interactions ovule defense. An example enzyme activity provided. Chitinase was detected Pseudotsuga menziesii (Douglas-fir) using both biochemical in-gel assay. This shows one putatively identified active probably assists defending against fungi.
