Differential In Silico Expression of Hevea brasiliensis COBRA Transcripts

摘要

In this paper, the expression values of 13 HbCOBL transcripts have been analyzed using the Tuxedo Software Suite protocol in two sets of tissue and treatments in Hevea brasiliensis. The first was in bark and latex of rubber clone Reyan 7-33-97 without ethrel treatment and the second was in ethrel-treated mature trees. A mapping of the transcriptomic data from those two sets was carried out against the reference genome Reyan 7-33-97. Two HbCOBL transcripts (HbCOBL-E and HbCOBL-P) showed significant differences of expression in bark but not in latex suggesting that these genes might be involved in the differentiation of laticifers. In addition, no HbCOBL transcripts were differentially regulated by ethylene suggesting that these genes might be regulated by another hormonal pathway in rubber tree.
