Quantitative analysis of expression patterns of <i>HvCKX</i> genes.

<p>(A) <i>HvCKX1</i>, (B) <i>HvCKX9</i>, (C) <i>HvCKX4</i>, (D) <i>HvCKX5</i>, (E) <i>HvCKX11</i> expression in different tissues and organs of developing plants of two barley cultivars, Golden Promise (left side) and Scarlett (right column). Total RNA was extracted from: 1) 3-day old seedlings, 2) roots from 5-day old seedlings, 3) meristems from 5-day old seedlings, 4) leaves from 5-day old seedlings, 5) developing leaves from 3–4 week old plants, 6) fully developed leaves from 3–4 week old plants, 7) inflorescences 3–4 cm long, 8) inflorescences 6–8 cm long, 9) developing kernels 0 DAP, 10) developing kernels 7 DAP, 11) developing kernels 14 DAP. The level of expression was related to the root = 1.00 (A) or fully developed leaves = 1.00 (B,C,D,E).
