Effects of Rotenoids on Isolated Plant Mitochondria [PDF]
Plant Physiology, 1984 The effects of several rotenoids have been studied on potato (Solanum tuberosum L.) tuber and etiolated mung bean (Phaseolus aureus Roxb.) hypocotyls mitochondria. The selective inhibition of mitochondrial complex I is characterized by several tests: (a) no effect can be observed on exogenous NADH or succinate oxidation; (b) malate oxidation is ...

Advances in Agriculture, Volume 2022, Issue 1, 2022., 2022 The world population is projected to be 9.1 billion by the year 2050, and about 70% extra food will be required. One of the main challenges regarding food security is postharvest loss due to insect pests. The overall postharvest grain losses for sub‐Saharan Africa could be as high as US$4 billion/year.
