Abstract Brassica napus L. is one of the most important oilseed crops in the world, providing oil and protein used for food, fuel, and industrial purposes. Despite high oil yields and desirable agronomic traits, its geographical range is mainly limited to temperate climates, and oil yields and quality are negatively impacted by drought and heat stress. Leaf cuticular waxes are known to protect plants from many forms of environmental stress, including those caused by drought and heat. To shed… Expand
A combination of genome-wide association study and transcriptome analysis in leaf epidermis identifies candidate genes involved in cuticular wax biosynthesis in Brassica napus
TLDR
Combination of GWAS with transcriptomic analysis revealed a number of directly or indirectly wax-related genes and their associated SNPs that could provide clues for further validation of SNPs for marker-assisted breeding and provide new insights into the genetic control of wax biosynthesis and improving stress tolerance of B. napus.

Characterization of leaf cuticular wax classes and constituents in a spring Camelina sativa diversity panel
TLDR
Results suggest that modifying specific wax constituents could increase the wax loads, which in turn could enhance cuticle composition and properties, and enable the development of molecular markers for molecular breeding programs aimed at increasing drought tolerance of Camelina. Expand
Quantification of leaf wax and cutin monomer composition in Pima (Gossypium barbadense L.) and upland (G. hirsutum L.) cotton
Abstract Climatological drought is a historic problem that limits agricultural production worldwide. Reducing transpirational water loss can conserve soil moisture and confer drought tolerance toExpand
Exogenous hormones influence Brassica napus leaf cuticular wax deposition and cuticle function
TLDR
Findings that B. napus leaf wax composition and cuticle permeability are altered by exogenous SA, MeJA and ACC suggest that the hormone treatments affect wax composition, and that the changes in wax profiles would cause changes in cuticles permeability. Expand
Chemical variation for fiber cuticular wax levels in upland cotton (Gossypium hirsutum L.) evaluated under contrasting irrigation regimes
TLDR
The findings suggest that the biosynthetic pathways associated with these compounds are contributing to the phenotypic variability of these two important fiber quality traits and thus the biochemical pathwaysassociated with cuticular fiber wax are candidates for metabolic engineering via molecular breeding approaches.

Screening for Natural Variation in Water Use Efficiency Traits in a Diversity Set of Brassica napus L. Identifies Candidate Variants in Photosynthetic Assimilation
TLDR
This research illustrates the importance of examining natural variation at a physiological level for investigation of the underlying mechanisms influencing the diversity of carbon isotope discrimination values in the field and identifies natural variants in B. napus with improved WUE and potential relevant traits.

Regulation of cuticular wax biosynthesis in plants under abiotic stress
Cuticular waxes are the covering of the outer layer of the plant, consist of hydrocarbon appears like whitish film or bloom in plant organs. They play a vital role like a safeguard from differentExpand
hemical variation for fiber cuticular wax levels in upland cotton Gossypium hirsutum L . ) evaluated under contrasting irrigation egimes lison
The fiber from upland cotton (Gossypium hirsutum L.) makes up approximately 90% of the global cotton produced each year. Fiber quality is important to textile mills for processing and factors intoExpand
Evaluation of the Foliar Damage That Threatens a Millennial-Age Tree, Araucaria araucana (Molina) K. Koch, Using Leaf Waxes
TLDR
The leaves of sick individuals have lower values of distribution indices as foliar damage increases that are interpreted as a reduction of in vivo biosynthesis of waxes. Expand
Population Genomic Analysis Reveals Differential Evolutionary Histories and Patterns of Diversity across Subgenomes and Subpopulations of Brassica napus L.
TLDR
This study used sequence-based genotyping to identify and genotype 30,881 SNPs in a diversity panel of 782 B. napus accessions, and detected strong population structure broadly concordant with growth habit and geography, and identified three major genetic groups: spring (SP), winter Europe (THE AUTHORS), and winter Asia (WA).

Seedling development in a Brassica napus diversity set and its relationship to agronomic performance
TLDR
The reduction of phenotypic diversity was on average more pronounced for the seedling development traits than for the agronomic and seed quality traits, suggesting that plant breeders need to introgress new genetic variation with respect to the former. Expand
Morpho-physiological Response of Selected Brassica Lines to Moisture Stress
TLDR
Brassica juncea was the earliest in reaching maturity followed by B. carinata and B. napus, respectively, while lines showed little differences, while genotypic differences were significant for pod length, number of pods/main stock and number of secondary branches and non-significant for number of seed/pod and grain yield/plant.

Fruit cuticle lipid composition and water loss in a diverse collection of pepper (Capsicum).
TLDR
The resources described here will be valuable for future studies of the physiological function of fruit cuticle, for the identification of genes and QTLs associated with fruit cuticles synthesis in pepper fruit, and as a starting point for breeding improved fruit quality in pepper. Expand
The effect of drought stress on qualitative and quantitative traits of spring rapeseed (Brassica napus L.) cultivars.
TLDR
It can be concluded that RGS003 cultivar had better capability to tolerate drought stress and could produce greater seed yield under stress conditions. Expand
Assessment of Cold and Heat Tolerance of Winter‐grown Canola (Brassica napus L.) Cultivars by Pollen‐based Parameters
TLDR
Winter-grown canola (Brassica napus L.) production is limited mostly by frost and winter kill in the southern canola-growing regions of the United States, so identified cold- and heat-tolerant cultivars may be useful inCanola-breeding programmes to develop cultivars suitable for a niche environment.

TLDR
Novel loci identified for flag leaf glaucousness and the wide phenotypic variation within the DH population offers considerable scope to investigate the impact and value of this trait for bread wheat production in southern Australia. Expand
Overexpression of Transcription Factor OsWR2 Regulates Wax and Cutin Biosynthesis in Rice and Enhances its Tolerance to Water Deficit
TLDR
It is demonstrated in this report that OsWR2 regulates wax and cutin biosynthesis differently than does the OsWR1 homologue, and plays a major role in controlling cuticle permeability. Expand

An integrative functional approach demonstrates a direct relationship between cuticular transpiration barrier properties and distinct chemical modifications in cuticular wax composition during the course of tomato fruit development. Expand
