Project description:We report the expression analysis of seed kernel in Camellia oleifera cultivars. In total 221 cultivars are sequenced by the Illumina sequencing experiments to obtain the gene expression profiles.
Project description:To identify the important genetic resources of tea oil accumulation and quality formation in Camellia oleifera, an important woody edible oil tree native to Southern China, we have designed and customized an expression profile chip of C. oleifera with 8×60 K on the basis of transcriptome sequencing of multiple tissue samples including kernels, roots, and leaves from multiple varieties. we used the mcroarrays to determine the gene expressions in kernel development of C. oleifera elite varieties'Huashuo' , 'Huaxin' , 'Huajin' and 'Jujian' respectively. Microarray results indicated a total of 10710 gene probes showed stable differential expression in the comparation of August vs June and 9987 in the comparation of October vs August. PATHWAY enrichment results of DEGs indicated that the oil synthesis and accumulation occured in the whole kernel development of C. oleifera, but were mainly concentrated from the nutrition high-speed synthesis period to the seed mature period, which was consistent with the variation trend of oil content and fatty acide composition in C. oleifera kernel development.
