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:
... The effect of contrasting environmental growth conditions (in vitro tissue culture, ex vitro acclimatisation, climate chamber, greenhouse and outdoor) on leaf development, cuticular wax composition, and foliar transpiration of detached leaves of the Populus × canescens clone 84 K were investigated. Our results show that total amounts of cuticular wax increased more than 10‐fold when cultivated in ...

Abstract:
... The aim of this paper was to identify changes in the crystal morphology, chemical composition and key gene expression of 'Suichuan' kumquat cuticular waxes after hot water dipping treatment (HWD), before and after cold storage, as well as the relationship of cuticular waxes with storage performance improvement. Scanning electron microscopy (SEM) showed a rearrangement of epicuticular wax layers af ...

KEY MESSAGE: We identified two poplar clones of the same species as highly comparable, yet clones of two further species of the same genus to be distinctly different regarding multiple morphological and ecophysiological traits. Leaf morphology, wax composition, and residual (cuticular) transpiration of four poplar clones (two clones of the hybrid species P. × canescens, P. trichocarpa, and P. euph ...

The present study conducted in and around the Durgapur Industrial region, West Bengal, India aims to characterize the air pollution indicator parameters and identify the pollution tolerant species by detailed analysis of 21 morphological and biochemical parameters under the air pollution stress. Two plants species Ficus benghalensis (FIBE) and Terminalia arjuna (TEAR) were selected as the models f ...

Abstract:
... Epicuticular waxes are important natural compounds that influence cuticle properties and can protect fruit from factors that harm its external quality. We demonstrated that, at a dose that reduces postharvest citrus fruit quality loss (4 d 2 µL L⁻¹), ethylene redirected epicuticular wax metabolism towards the synthesis of primary alcohols, mostly behenyl alcohol, by favouring the acyl-reduction pa ...

Abstract:
... Heat stress events (heatwaves) significantly impair grapevine leaf and berry physiology. The prevalence and frequency of heatwaves are predicted to increase in the coming decades, even in moderate climates. Despite this, many facets of heatwave effects on grapevine physiology remain unstudied. In this work, we subjected potted Gewürztraminer grapevines to a single heatwave event at mid-ripening or ...

... Identifying compounds present in the sugarcane epicuticular wax and using these compounds to classify the genotypes susceptible and resistant to the initial attack of sugarcane borer (Diatraea saccharalis) was the aim of this study. A greenhouse experiment was performed in a factorial scheme with and without borer infestation using genotypes previously characterized as resistant or susceptible in ...

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 ...
... Histological studies of stem, root and leaf of ovule and embryo cultured haploid and diploid plantlets of Citrus grandis × C. sinensis and Citrus grandis × C. limetta crosses were carried out. Area of xylem and phloem in stem increased gradually with increasing age of explants in both cross combinations; however, it was measured minimum in haploid plantlets (1.95 and 1.62 mm², respectively) as com ...

... Conchocarpus is the largest genus in the subtribe Galipeinae, tribe Galipeeae, distributed from Nicaragua to northern Bolivia and southern Brazil, with the center of species diversity in the Brazilian Atlantic Rainforest. Five species were recently segregated to a new genus (Dryades), thereby restoring the monophyly of Conchocarpus sensu stricto. In addition to the wide morphological diversity of ...

Abstract:
... Cuticular wax has been implicated in the first line of plant defense mechanism against external stresses. In this study, cuticular wax on the fruits of two rabbiteye blueberry cultivars cv. Baldwin and Brightwell were examined in terms of the morphology and chemical composition during fruit development in the presence and absence of pre-harvest melatonin (MT) treatment. It revealed that the crysta ...
... The aerial surfaces of plants are covered by a layer of cuticular wax that is composed of long-chain hydrocarbon compounds for protection against adverse environmental conditions. The current study identified a maize (Zea mays L.) APETALA2/ethylene-responsive element-binding protein (AP2/EREBP)-type transcription factor, ZmEREB46. Ectopic expression of ZmEREB46 in Arabidopsis increased the accumul ...

Abstract:
... The diamondback moth (DBM), Plutella xylostella, is an oligophagous pest of cruciferous crops worldwide. Host plants of the DBM possess epicuticular wax, but thick wax is unfavorable to the selection of oviposition sites for female DBMs. How the DBM responds to host plant wax regarding oviposition site selection is largely unknown. The glucosinolates and wax levels in the cotyledons and true leave ...

... Large enzyme families catalyze metabolic diversification by virtue of their ability to use diverse chemical scaffolds. How enzyme families attain such functional diversity is not clear. Furthermore, duplication and promiscuity in such enzyme families limits their functional prediction, which has produced a burgeoning set of incompletely annotated genes in plant genomes. Here, we address these chal ...
... The fruit surface has an enormous impact on the external appearance and postharvest shelf‐life of fruit. Here, we report two functionally redundant genes, PpMYB25 and PpMYB26, involved in regulation of fruit skin texture in peach. PpMYB25 can activate transcription of PpMYB26 and they both induce trichome development and cuticular wax accumulation, resulting in peach fruit with a fuzzy and dull ap ...
