Gene expression and plant performance in oryzacystatin-I expressing transformed tobacco (Nicotiana tabacum L. cv Samsun) plants under abiotic stress

Beyene, Getu (University of Pretoria, 2006-12-05)

Plant cysteine proteinase inhibitors or also called phytocystatins inhibit the action of cysteine proteinases in plants. These proteinases are involved in many developmental processes by degrading proteins. In this study ...
Production and characterization of transgenic Arabidopsis and soybean (Glycine max (L.) Merrill.) plants over-expressing oryzacystatin I (OC-I)

Makgopa, M.E. (Matome Eugene) (University of Pretoria, 2014)

In legumes, drought causes early senescence due to loss of the symbiotic relationship between the plant and the rhizobacterium. Senescence is characterized by increases in proteolytic enzymes required for protein recycling ...
Proteases and protease inhibitors involved in plant stress response and acclimation

Prins, Anneke (University of Pretoria, 2009-04-07)

Proteases play a crucial role in plant defence mechanisms as well as acclimation to changing metabolic demands and environmental cues. Proteases regulate the development of a plant from germination through to senescence ...
