Tissue-specific expression of McHAK genes. 3′-UTR
regions of McHAK1, McHAK2, and McHAK3
and the EST sequence AI547371 of McHAK4 were hybridized to
total RNA extracted from unstressed plants (except flower and seed
pot). Tissues were specified as root (RT), stem (ST), leaf (LF), flower
(FL), and seed pot (SP). Actin was used as a loading control. McHAK1,
2.8 kb (lower band, 2.7 kb); McHAK2, 2.9 kb; McHAK3, 2.8 kb (lower
band, 2.7 kb); and McHAK4, 2.9 kb.
