Abstract:
... Drought stress limits fruit ripening and quality of grape cultivar, particularly with the use of root restriction. However, the mechanism involved in the molecular response to water deficit concomitant to agriculture adjustment remains poorly understood. In the present study, the regulation of two grape β-ketoacyl-CoA synthase (KCS) genes obtained with transcriptome analysis whose expression is si ...

Abstract:
... Cuticular waxes play an important role in plant survival in terrestrial environments. They are part of the cuticle and form a hydrophobic barrier associated with a decline in water loss through cuticular transpiration. Data on the chemical and morphological composition of cuticular waxes in Sapindales have been collected for more than 5th years. The present review compiles the data published for t ...

Abstract:
... The contributions of the cuticle and stem scar to blueberry water loss were evaluated in four cultivars. Among the cultivars, 55–69% of the water loss occurred through the cuticle, indicating the key role of the cuticle and cuticular waxes in restricting water loss. Cuticular wax content at harvest ranged from 38.12 to 67.00 μg cm⁻² across the four cultivars and increased during four-week postharv ...

Abstract:
... Water loss is a key factor for the postharvest senescence of fruit. It has been reported that natural cuticular wax at high concentrations has better performance than commercial coating in water retention of fruit, which can prevent postharvest water loss without the accumulation of off-flavor. Here, we analyzed the correlation between epicuticular wax and postharvest water loss with 75 citrus var ...

Abstract:
... Cuticular wax plays a critical role as a plant protectant against various environmental stresses. We predicted that the presence of the mutualistic fungal endophyte Epichloë gansuensis in Achnatherum inebrians would change both the composition of leaf cuticular wax as plants aged during the growing season and the gene expression levels associated with the wax biosynthesis pathway. Endophyte-infect ...

Abstract:
... Postharvest water loss causes fruit softening, wilting, and a decline in quality and commodity value. Cuticular wax is a key barrier against non-stomatal water loss and plays a crucial role in fruit quality maintenance. However, there has been limited research on the genetic basis of fruit wax and postharvest water loss. Here, we found that HJ (Citrus reticulata) and ZK (Poncirus trifoliata) fruit ...
