Organ expression profile of CsHMA5.1 and CsHMA5.2 in cucumber.
A, quantitative real time PCR analysis of CsHMA5.1 and CsHMA5.2 expression in roots, hypocotyls (hyp), cotyledons (cot), petioles (pet), and leaves. The letters indicate significant differences (p < 0.05) between CsHMA5.1 and CsHMA5.2 expression level in roots (a) or between the amount of CsHMA5.2 transcript in different cucumber organs. Inset, the semiquantitative reverse transcription-polymerase chain reaction analysis of CsHMA5.1 and CsHMA5.2 in the same organs. B, semiquantitative reverse transcription-polymerase chain reaction analysis of CsHMA5.1 and CsHMA5.2 expression in cucumber flowers and fruits. mp, male perianth; pist, pistils; fp, female perianth; stam, stamen.
