| Leaf lipoxygenases (LOX) are involved with important physiological processes such as plant growth and development, senescence, biosynthesis of regulatory molecules, and response to pathogens and insects. We did a biochemical evaluation of the LOX pathway of soybean leaves submitted to wounding in a normal genotype (IAC-100) and its counterpart lacking seed LOX (IAC-100 TN). Our results indicate that LOX activities in the different pHs and temperatures tended to be higher in the wounded plants compared to their respective controls. The K M app values at 168 h after wounding reached a minimum in both genotypes indicating that the plants respond by changing the leaf LOX pool. There was an increase on protease inhibitor levels in all time points after... |

| ABSTRACT A major problem in post-harvest handling of bananas is the individual detachment of the fruit from the hands. This study aimed to establishing the relationship between carbohydrate concentration and enzyme activity in the pedicel region of three cultivars of bananas, resistant and susceptible to natural dropping, during post-harvest ripening, and the susceptibility of bananas to finger dropping. Cultivars ‘Terra’ (plantain, AAB group) and ‘Prata’ (banana, AAB group) triploids and the ‘Prata Graúda’ (banana, AAAB group) tetraploid were used. The experiment was distributed in split plots, with three plots (cultivars) and five subplots (peel color stages) in a completely randomized design with three replications and three fruits per sample unit.... |
