Expressed sequence tags from larval gut of the European corn borer (Ostrinia nubilalis): Exploring candidate genes potentially involved in Bacillus thuringiensis toxicity and resistance

Table 1 Summary of the analysis of 15,000 ESTs from the guts of the European corn borer larvae

Library	Sequence direction	Number of clones sequenced	Chromatographs checked (EST number)		Sequence quality checked (EST number)		Average length (bp)	Number of contigs ^b	Number of singletons
			Good quality	Poor quality ^a	Good quality	Poor quality
Plasmid	3'-end	1,152	764	388	722	42	441
Uni-ZAP RX	5'-end	13,848	12,302	1,546	11,797	505	674
Total	--	15,000	13,066	1,934	12,519	547	656	1,157	1,738

^aThe poor quality sequences were discarded and were not included in the analysis.
^bThe numbers of contigs and singletons were based on the analysis of all the ESTs sequenced from the two libraries.
