Transcriptome Analysis of Bael (Aegle marmelos L.) a Member of Family Rutaceae

Aegle marmelos is a medicinally and horticulturally important tree member of the family Rutaceae. It is native to India where it is also known as Bael. Despite its importance; the genomic resources of this plant are scarce. This study presented the first-ever report of expressed transcripts in the leaves of Aegle marmelos. A total of 133,616 contigs were assembled to 46,335 unigenes with the minimum and maximum lengths of 201 and 14,853 bp. There were 7002 transcription factors and 94,479 simple sequence repeat (SSR) markers. The A. marmelos transcripts were also annotated based on information from other members of Rutaceae; namely Citrus clementine and Citrus sinensis. A total of 482 transcripts were annotated as cytochrome p450s (CYPs) and 314 transcripts were annotated as glucosyltransferases (GTs). In the A. marmelos leaves the monoterpenoid biosynthesis pathway was predominant. This study provides an important genomic resource along with useful information about A. marmelos.
