Understanding the molecular mechanisms of plant response to unfavorable conditions is necessary for the effective selection of tolerant genotypes. Earlier, using high-throughput transcriptome sequencing of flax plants after exposure to aluminum ions (Al^(3+)) and high soil acidity, we detected stress-induced alteration in the expression of several genes, including CAX3, which encodes Ca^(2+)/H^(+)-exchanger involved in calcium ion transport. Here we describe CAX3 mRNA levels in flax cultivars either tolerant (Hermes and TMP1919) or sensitive (Lira and Orshanskiy) to Al^(3+). Stress-induced increased expression of CAX3 was detected only in aluminum-tolerant flax cultivars. The product of CAX3 gene may participate in flax response to high soil acidity and high Al^(3+) concentration through Ca^(2+)-mediated intracellular regulation. |
