Protein fractions in amaranth grain and their chemical characterization

Abstract: Protein distribution in each of two selections of Amaranthus caudatus, Amaranthus hypochondriacus, and Amaranthus cruentus was established. Some of these fractions were analyzed for their amino acid content. Two extraction sequences were used, which differed in the first solvent. The solvent sequence resulted in differences in fraction I (albumin), II (globulin), III (prolamine), V (glutelin-like), and some in fraction VI (glutelins). Albumins were rich in tryptophan, threonine, and lysine; globulins in sulfur amino acids and lysine; prolamines in threonine and leucine; and glutelins in tryptophan and leucine

Inheritance of some morphological traits in grain Amaranthus.

Abstract: Intraspecific crosses involving five cultivars of Amaranthus hypochondriacus and two from A. caudatus were studied to investigate the inheritance of five morphological traits (seed coat colour, inflorescence colour, seedling colour, oval leaf mark and purple leaf mark). Seedling colour, inflorescence colour, seed coat colour and oval leaf mark segregated to a 3:1 ratio and therefore each was controlled by a single dominant gene. The purple leaf mark segregated in 9:7 ratio and hence may be controlled by two dominant genes. Simultaneous segregation for seed coat colour and inflorescence colour gave a ratio of 9:3:3:1. Similar genetic ratio was observed for the simultaneous segregation for oval leaf mark and inflorescence colour. It was suggested that each of these traits is controlled by independent genes.

Rubisco from Amaranthus Hypochondriacus

Abstract: Rubisco (ribulose 1, 5-Msphosphate carboxylase-oxygenase E.CT.4.1.1.39.) from C-4 plants have not yet been extensively studied. Badger and Andrews(1) have isolated rubisco from Zea mays and found it’s Km(CO2) higher than that from C-3 plants, but this is stilx in controversy(2).

Effect of the Salinity on the ATPase Activity (CF1, F1) Electron Transport in Photosystems I,II and Respiratory Chain in Medicago sativa and Amaranthus hypochondriacus

Abstract: In the plant salt adaptation, the ATPases are interesting because of their role in H+ or ion transport (1,2). However, little in known about the participation, and similarities or differences between F1 ATPases and CF1 ATPases activities from higher plants in the resistance to salinity. ()). Also, there is not conclusive — information on the electron flow in PSI, PSII and respiratory chain in halophytes or glycophytes grown under different salinity conditions (3,4,5).
