Abstract excerpt
Despite extensive biochemical analyses, the biological function(s) of plant beta-amylases remains unclear. The fact that beta-amylases degrade starch in vitro suggests that they may play a role in starch metabolism in vivo. beta-Amylases have also been suggested to prevent the accumulation of highly polymerized polysaccharides that might otherwise impede flux through phloem sieve pores. The identification and...
