Relative expression profile of the 10
AtSK genes compared with 10 reference genes in Arabidopsis
organs. The transcript level is represented as a ratio (R) of the
absolute value of the studied gene to the absolute value of the
ACT2/ACT8 genes. Due to the ratio calculation, the
sds are not represented on this figure. The
transcript levels have been tested on RNA extracted from roots (R),
rosette leaves (RL), cauline leaves (CL), inflorescence stems (IS),
flower buds (FB), open flowers (OF), siliques (SI), and seedlings (S).
A, Distribution of AtSK transcripts. B, Distribution of the
AtMAP3Kε and AtMAP4Kα transcripts. C,
Distribution of Ats1A and RD29A transcripts. Two
scales are provided on the y axis, each with the color of
the corresponding gene. D, Distribution of SUP,
MEA, AS1, and SCR transcripts. Like in
C, two scales are provided with colors matching the genes.
