Citrullus lanatus subsp. vulgaris strain:Dumara Transcriptome or Gene expression

Many fruits, including watermelon, are proficient in carotenoid accumulation during ripening. While most genes encoding steps in the carotenoid biosynthetic pathway have been cloned, few transcriptional regulators of these genes have been defined to date. Here we describe the identification of a set of putative carotenoid-related transcription factors resulting from fresh watermelon carotenoid and transcriptome analysis during fruit development and ripening. Our goal is to both clarify the expression profiles of carotenoid pathway genes and to identify candidate regulators and molecular targets for crop improvement.

包括西瓜在内的诸多果实，在成熟过程中均可高效积累类胡萝卜素（carotenoid）。尽管类胡萝卜素生物合成通路各催化步骤对应的编码基因大多已被克隆，但截至目前，针对这些基因的转录调控因子仍鲜有被明确鉴定的案例。本研究通过对果实发育与成熟阶段的新鲜西瓜样本开展类胡萝卜素与转录组（transcriptome）分析，成功鉴定得到一批潜在的类胡萝卜素相关转录因子（transcription factors）。本研究旨在明确类胡萝卜素通路基因的表达谱，并筛选可用于作物遗传改良的候选调控因子与分子靶点。
