Petunia integrifolia Transcriptome or Gene expression

Petunia hybrida (petunia) is one of the most economically important annual bedding plants in the United States. Genomic resources for petunia are lacking. Utilizing RNA-seq, de novo transcriptome assemblies were generated for the progenitor species of cultivated petunia, Petunia axillaris and P. integrifolia, and for P. exserta, a rare species that has been utilized in petunia breeding and as a model to understand pollination syndrome. Transcripts were derived from five tissue types: seedlings, callus, mixed floral developmental stages, shoot apices and trichomes. The transcriptome assemblies are being utilized for molecular marker development and gene discovery for traits of interest in Petunia.

Petunia hybrida（紫茉莉）是美国经济价值最高的年度覆盖植物之一。紫茉莉的基因组资源匮乏。通过RNA测序技术，对栽培紫茉莉的原始物种Petunia axillaris和P. integrifolia，以及作为紫茉莉育种材料并用于解析传粉综合征模型的稀有物种P. exserta进行了从头转录组组装。转录组由五种组织类型生成：幼苗、愈伤组织、混合花发育阶段、茎尖和毛状体。这些转录组组装正在被应用于紫茉莉中感兴趣性状的分子标记开发与基因发现。
