a
Total desiccation-specific up-regulated transcriptome contains 406 genes.
b
Total genome contains 9,225 genes.
c
z scores were calculated as described by Doniger et al. (12), except that genomic figures were used to approximate the number of genes measured by our microarray.
d
Number in genome taken from McLeod et al. (26).
e
Number in genome determined by keyword search of gene annotations.
f
N/A, not available.
