  • Effect of exogenous NO gas on the ripening of pepper fruits. NO (5 p.p.m.) was either applied or not applied to fruits at an early breaking point stage for 1 h. Then, peppers were incubated at room temperature for 3 d.

    Ripening of pepper fruit and reactive nitrogen species

    Pepper (Capsicum annuum, Solanaceae) fruits are consumed worldwide and are of great economic importance. In most species ripening is characterized by important visual and metabolic changes, the latter including emission of volatile organic compounds associated with respiration, destruction of chlorophylls, synthesis of new pigments (red/yellow carotenoids plus xanthophylls and anthocyanins), formation of pectins and protein […] More

    Zinc stress and ROS and RNS metabolism of roots

    Zinc (Zn) is an essential micronutrient naturally present in soils, but anthropogenic activities can lead to accumulation in the environment and resulting damage to plants. Heavy metals such as Zn can induce oxidative stress and the generation of reactive oxygen and nitrogen species (ROS and RNS), which can reduce growth and yield in crop plants. […] More
