Maltose is the major form of carbon exported from the chloroplast at night as a result of transitory starch breakdown. Maltose exists as an alpha- or beta-anomer. We developed an enzymatic technique for distinguishing between the two anomers of maltose and tested the accuracy and specificity of this
Transitory starch is accumulated during the day and is the main source of energy for the cell metabolism during the night. The observed periodical starch degradation has become a model often used by scientist in their experiments. Starch granule degradation could be divided into 2 periods:
Three genes, BE1, BE2, and BE3, which potentially encode isoforms of starch branching enzymes, have been found in the genome of Arabidopsis thaliana. Although no impact on starch structure was observed in null be1 mutants, modifications in amylopectin structure analogous to those of other branching
