Project description:Gerbera delavayi Franch. endemic to southwest China, is a rare fiber plant. In this study, the leaves of G. delavayi were sequenced based on Illumina Hi-Seq2500. The results showed that 108694 unigenes were found. N50 was 593.90bp, and the mean length was 912bp. By comparing with Nr and Swiss-prot database, 40915 unigenes were annotated, and 67779 unigenes were unannotated. In addition, 30 unigenes had homology with Ces family, 20 unigenes had homology with Cls family, and 11 unigenes had homology with SuSy. 11369 unigenes were assigned to 25 categories with COG database, and 21378 unigenes were divided into 52 GO terms. Function annotation against KEGG database obtained 8087 unigenes and 118 pathways. 47 unigenes were found at “phenylpropanoid biosynthesis” pathway. Furthermore, 4908 unigenes contained 5179 SSRs, 1 SSR occurred every 12.46kb. The largest number of SSR type was mono-nucleotide repeat, and its frequency was 54.37%; the next was di-nucleotide repeat and tri-nucleotide repeat, with the frequencies of 22.90% and 21.70%, respectively. These results greatly enriched the genetic information of G. delavayi, and provided basic data for genetic breeding and exploitation of this unique plant resource.
Project description:Gerbera inflorescence sample was compared with a gerbera leaf sample in order to identify flower specific genes. Samples were pooled from different developmental stages and alltogether 8 replicates (including 2 biological replicates with 4 technical replicates each) were independently labelled. Both biological replicates included two dye swap replicates. Gerbera 9K cDNA microarrays were used for the hybridizations.
Project description:Three different developmental stages of ray and disc flowers of gerbera hybrida were compared to each other using gerbera 9K cDNA microarray.
