^aThese data are obtained from http://genome-www5.stanford.edu.

^bAll data are corresponding with fluorescence intensities greater than 500 in both channels and ch2:ch1 normalized ratio ≧2.0 or ≦0.5.

^cWhen searching dbEST with BLASTN, we find Arabidopsis EST corresponding to four of our AtTLPs represented on microarray data generated by AFGC. AtTLP2 is corresponding to the EST clones 289B10T7 and 173K22T7. AtTLP7, AtTLP9, and AtTLP10 are corresponding to the EST clones 173G1T7, 201E19T7, and F3E6T7, respectively.

^dIt is the mutant of massugu gene, which has meanwhile been officially renamed to NPH4 (nonphototropic hypocotyl 4) gene.
