摘要: Pollen germination is an essential process for plant reproduction. Many studies related to gene expression of pollen were conducted in Arabidopsis and rice. But similar research on oil palm is very limited. Therefore, transcriptional profiling analysis of pollens from three oil palm fruit forms (Dura, Pisifera, Tenera) was performed to investigate the changes in gene expression after pollen germination and to understand the related molecular mechanisms. De novo assembly identified a total of 149,726 unigenes with the total length, average length, N50 and GC content of 202,061,188 bp, 1349 bp, 2131 bp and 43.76% respectively. A total of 13629, 4305 and 3087 differentially expressed genes (DEGs) were discovered for Dura, Pisifera and Tenera pollens. Furthermore, different DEGs in plant hormone signal transduction pathway were observed in Dura (195), Pisifera (59) and Tenera (45) during KEGG analysis, suggesting that plant hormones may play an important role in Dura than Pisifera and Tenera. Moreover, expression profiles of 6 genes involved in pollen germination showed that most genes were up-regulated and expression of some genes was much higher after germination in both Pisifera and Tenera, indicating Dura has a different mechanism with Pisifera and Tenera.
