Sep 23, 2019 · This process involves auxin-dependent activation of expression of starch-synthesis genes including PGM, ADG1 and SS4. The promoters of PGM and ADG1 contain …

Apr 28, 2022 · To assess the sensitivity of ADPG to unintentional shading during leaf sampling, rosettes were harvested from WT, pgm and adg1 Arabidopsis plants in the light either by …

The classical pathway of starch synthesis in Arabidopsis leaves involves the chloroplastic enzymes phosphoglucomutase (PGM), which generates Glc-1-P from Glc-6-P, and ADPGlc …

May 20, 2019 · To further confirm that the starch granule synthase genes SS4, PGM and AGD1 are the key genes regulated by auxin and that they function downstream of auxin signaling, we …

We isolated pgi1-1, an Arabidopsis mutant with a decreased plastid phospho-glucose (Glc) isomerase activity. While pgi1-1 mutant has a deficiency in leaf starch synthesis, it …

Glucose content in the cytosolic heteroglycan increased substantially in adg1-1 but decreased in pgi1-2, suggesting that the plastidic Glc6P pool contributes to its biosynthesis. The abundance …

It is universally accepted that transitory starch is synthesized from ADP-glucose (ADPG) in the chloroplasts.

promoters of PGM and ADG1 contain sequence motifs that are typical of auxin-response elements, suggesting a direct effect of auxin signaling on the expression of these genes.

First, if the consensus pathway operates, levels of ADPG and starch would be expected to be much lower in leaves lacking PGM or AGPase (the pgm and adg1 (aps1) mutants, …

To characterize further the role of autophagy in carbon metabolism, we generated double mutants containing a starchless mutation, phosphoglucomutase ( pgm ; Caspar et al., 1985) or ADP …
