Mining the bitter melon (momordica charantial.) seed transcriptome by 454 analysis of non-normalized and normalized cDNA populations for conjugated fatty acid metabolism-related genes

Table 4 Numbers of total transcript reads and contigs comprising different categories of lipid genes from 454 analysis of normalized cDNA from developing bitter melon seeds.

Categories	Numbers of reads	Numbers of contigs	Numbers of Arabidopsis homologs
Fatty acid synthesis in plastids	1,462	63	31
Synthesis of plastid membrane lipids	100	10	6
Synthesis of endomembrane lipids	674	59	31
Acyl-lipid metabolism in mitochondria	492	33	19
Synthesis and storage of oil	235	10	7
Storage lipid and fatty acid degradation	482	38	19
Lipid signaling	761	97	48
Fatty acid elongation & wax and cutin
metabolism	108	7	5
Miscellaneous	845	78	43

Also shown are the numbers of unique homologs of known Arabidopsis genes in the assembled contigs. The categories are based on those used in the Arabidopsis Lipid Gene database [33].
