Project description:To test the impacts of drought on the host and fungus, we inoculated carrots (Daucus carota cv. ‘Napoli’) with spores of Rhizophagus irregularis DAOM 197198. Carrots grew in a greenhouse, and at the beginning of taproot development, were exposed to a 10-day water restriction. We evaluated plant growth and physiological responses, colonization level, and plant and fungal gene expression.
Project description:Effect of betanin synthesis on the metabolism of transgenic carrot. Betalain is a natural pigment with important nutritional value and broad application prospects. Previously, we produced betanin biosynthesis transgenic carrots via expressing optimized genes CYP76AD1S, cDOPA5GTS and DODA1S. Betanin can accumulate throughout the whole transgenic carrots. But the effects of betanin accumulation on the metabolism of transgenic plants and whether it produces unexpected effects are still unclear.
Project description:Cultivated carrot (Daucus carota L. ssp. sativus) was domesticated from wild carrot (Daucus carota L. ssp. carota) with radical different traits. The aim of this study was to compare the root transcriptomes between cultivated and wild carrots for SNP discovery, inferring domestication process, and identifying domestication genes. Six cultivated carrots representing main European carrot root types and five wild carrot populations from widely dispersed sites were used. The root transcriptomes were sequenced with multiplexing paried-end sequencing in Illumina Genome Analyzer IIx.
