Table 2.

The numbers of mapped reads and assembled unigenes.

Samples	Sequenced reads	Mapping ratio (%)	Total consensus sequences	Distinct clusters	Distinct singetons
Resistant-0	73,659,506	92.0	105,900	35,928	69,972
Reisitant-1	71,287,722	91.8	120,531	34,640	85,891
Resistant-2	73,094,738	91.3	98,840	32,319	66,521
Susceptible-0	70,721,532	92.0	96,611	31,201	65,410
Susceptible-1	72,176,332	91.9	85,628	24,417	58,211
Susceptible-2	72,072,732	92.3	93,055	28,477	64,608
Total	433,012,562		600,565	53,829	410,613

Total Consensus Sequences represents all the assembled unigenes; Distinct Clusters represents the cluster unigenes; The same cluster contains some highly similar (more than 70%) unigenes, and these unigenes may come from same gene or homologous gene; Distinct Singletons means that this unigene come from a single gene. The number 1 and 2 represent drought treatment time for 1 and 2 h, respectively.
