Project description:Canna indica L. is an ornamental plant with petaloid staminodes and only a half fertile stamen in its flowers. The genetic basis for petaloid androecium remains unclear. In order to get comprehensive transcriptome data for further studies, RNA-Seq analysis were carried out. Two libraries from flower primordia and differentiated flowers of Canna indica were constructed and sequenced respectively, and totally 118,869 unigenes were assembled. The unigenes were aligned to the protein databases NR, NT, Swiss-Prot, KEGG, COG and GO (e-value<0.00001), and totally 67,299 unigenes were annotated. Our data constitute a preliminary basis for further studies on flower development of Canna indica.

Our data constitute a preliminary basis for further studies on flower development of Canna indica. The two samples from flower primordium and differentiated flower were sequenced for transcriptome assembly, and gene expression information of the two stages was also obtained from these data.
Project description:In Canna indica L, 3-4 (occasionally 5) petaloid staminodes and a one-theca stamen with a petaloid appendage constitute the androecium. In order to find out the genetic basis of petaloid development of androecium members, RNA-Seq analysis of petal (P), petaloid staminode (PS), anther (A) and petaloid appendage (PA) were carried out.

In order to find out the genetic basis of petaloid development of androecium members, RNA-Seq analysis of petal (P), petaloid staminode (PS), anther (A) and petaloid appendage (PA) were carried out. P-PS comparison was carried out to find the differences between the two kinds of petal-like organ, and A-PA comparison was conducted to reveal the mechanism for the differentiation of these two parts within stamen.
