Jasmonic acid regulates various abiotic stress responses but its role in regulation of copper (Cu) homeostasis has been poorly studied. This present study was conducted to explore the potential of jasmonic acid (JA) to enhance copper (Cu) tolerance in Cajanus cajan seedlings in terms of photosynthetic pigments, osmolytes and antioxidants. Seeds treated with different concentration (0, 1 µM, 1 nM and 1 pM) of JA... Read more.

Effect of cassava brown streak disease on cassava root storage components were studied on four Ugandan varieties with varying levels of tolerance. Significant differences (P<0.05) were observed with reductions of 30% in amylose content and 50% in amylopectin content of diseased compared to healthy plots. Average dry matter content of diseased plots was 25% higher as much as starch yield and starch content reduced by... Read more.
