Drought stress activates several defense responses in plants, such as stomatal closure, maintenance of root water uptake, and synthesis of osmoprotectants. Accumulating evidence suggests that deposition of cuticular waxes is also associated with plant responses to cellular dehydration. Yet, how cuticular wax biosynthesis is regulated in response to drought(More)
Hot pepper (Capsicum annuum), one of the oldest domesticated crops in the Americas, is the most widely grown spice crop in the world. We report whole-genome sequencing and assembly of the hot pepper (Mexican landrace of Capsicum annuum cv. CM334) at 186.6× coverage. We also report resequencing of two cultivated peppers and de novo sequencing of the wild(More)
All aerial parts of vascular plants are covered with cuticular waxes, which are synthesized by extensive export of intracellular lipids from epidermal cells to the surface. Although it has been suggested that plant lipid transfer proteins (LTPs) are involved in cuticular lipid transport, the in planta evidence is still not clear. In this study, a(More)
The aerial parts of plants are covered with a cuticle, a hydrophobic layer consisting of cutin polyester and cuticular waxes that protects them from various environmental stresses. Cuticular waxes mainly comprise very long chain fatty acids and their derivatives such as aldehydes, alkanes, secondary alcohols, ketones, primary alcohols, and wax esters that(More)
The aerial parts of all land plants are covered with hydrophobic cuticular wax layers that act as the first barrier against the environment. The MYB94 transcription factor gene is expressed in abundance in aerial organs and shows a higher expression in the stem epidermis than within the stem. When seedlings were subjected to various treatments, the(More)
Cuticular waxes are synthesized by the extensive export of intracellular lipids from epidermal cells. However, it is still not known how hydrophobic cuticular lipids are exported to the plant surface through the hydrophilic cell wall. The LTPG2 gene was isolated based on Arabidopsis microarray analysis; this gene is predominantly expressed in stem epidermal(More)
Very-long-chain fatty acids (VLCFAs) with chain lengths from 20 to 34 carbons are involved in diverse biological functions such as membrane constituents, a surface barrier, and seed storage compounds. The first step in VLCFA biosynthesis is the condensation of two carbons to an acyl-coenzyme A, which is catalyzed by 3-ketoacyl-coenzyme A synthase (KCS). In(More)
Microsomal delta-12 fatty acid desaturase (FAD2) functions in the first committed step of the biosynthesis of polyunsaturated fatty acids via the desaturation of oleic acid to linoleic acid. In this study, two FAD2 genes were identified through genome-wide analysis of Brassica rapa. One BrFAD2-1 gene harbors functional sequence information, but another(More)
Camelina has been highlighted as an emerging oilseed crop. Transgenic Camelina plants overexpressing Arabidopsis MYB96 exhibited drought resistance by activating expression of Camelina wax biosynthetic genes and accumulating wax load. Camelina (Camelina sativa L.) is an oilseed crop in the Brassicaeae family with potential to expand biofuel production to(More)
