Merremia emarginata plants were treated with different plant growth regulators (PGRs): naphthyl acetic acid (NAA), phenyl acetic acid (PAA) and gibberellic acid (GA 3). To determine the role of wall stiffening enzymes in internode elongation, IAA oxidase and peroxidase in the presence of different hydrogen donors like caffeic acid, chlorogenic acid and guaiacol were assayed. The levels of total...
Plants have evolved and adapted to different environments. Dwarfism is an adaptive trait of plants that helps them avoid high-energy costs under unfavourable conditions. The role of gibberellin (GA) in plant development has been well established. Several plant dehydration-responsive element-binding proteins (DREBs) have been identified and reported to be induced under abiotic and biotic stress ...
In the present study, 40 lines of peas, Pisum sativum L., from the Weibullsholm collection were examined for elongation response of the first internode to growth in soil, sand, or in darkness in air. The results obtained establish that appearance of the first (lowest) node of the epicotyl at the surface of soil was usual in only a few of the lines tested (L25, L1088, L1570). By contrast, appear...
Cryptochromes are blue light photoreceptors found in plants, bacteria, and animals. In Arabidopsis, cryptochrome 2 (cry2) is involved primarily in the control of flowering time and in photomorphogenesis under low-fluence light. No data on the function of cry2 are available in plants, apart from Arabidopsis (Arabidopsis thaliana). Expression of the tomato (Solanum lycopersicum) CRY2 gene was alt...
