Loss of starch granule initiation has a deleterious effect on the growth of Arabidopsis thaliana plants due to accumulation of ADP-glucose
Starch synthase 4 (SS4) is required for proper starch granule initiation in Arabidopsis thaliana, although starch synthase 3 (SS3) can partially replace its function. Unlike other starch deficient mutants, ss4 and ss3/ss4 mutants grow poorly even under long-day...

Cysteine-Generated Sulfide in the Cytosol Negatively Regulates Autophagy and Modulates the Transcriptional Profile in Arabidopsis
In Arabidopsis thaliana, DES1 is the only identified L-Cysteine desulfhydrase located in the cytosol, and it is involved in the degradation of cysteine (Cys) and the concomitant production of H2S in this cell compartment. Detailed characterization of the T-DNA...
