The efficiency of the C 4 photosynthetic pathway to suppress photorespiration and enhance carbon gain has led to a growing interest in its research. A comparative analysis of B. sinuspersici chloroplast genome with other genomes of Amaranthaceae was conducted. Results from a 70% cut off sequence identity showed that B. sinuspersici is closely related to Beta vulgaris with slight variations in the arrangement of few genes such ycf1 and ycf15; and, the absence of psbB in Beta vulgaris. B. sinuspersici has the largest 153, 472 bp while Spinacea oleracea has the largest protein-coding sequence 6,754 bp larger than B. sinuspersici. The GC contents of each of the species ranges from 36.3 to 36.9% with B. sinuspersici having the same GC percentage as Haloxylon persicum and H. ammodendron (36.6%). The IR size...

PEPC participates in photosynthesis by catalyzing the initial fixation of atmospheric CO2 and is abundant in both C4 and crassulacean acid metabolism leaves. PEPC is differentially expressed at different stages of plant development, mostly in leaves, but also in developing seeds. PEPC is known to show tissue-specific distribution in leaves and in other plant organs, such as roots, stems, and flowers. Plant PEPC undergoes reversible phosphorylation and monoubiquitination, which are posttranslational modifications playing important roles in regulatory processes and in protein localization. Phosphorylation activates the PEPC enzyme, making it more sensitive to glucose-6-phosphate and less sensitive to malate or aspartate. PEPC phosphorylation is known to be diurnally regulated and delicately changed in response to various environmental stimuli, in addition to light. PE...
