Intrinsic Mechanism of CaCl₂ Alleviation of H₂O₂ Inhibition of Pea Primary Root Gravitropism.

ABSTRACT: Normal root growth is essential for the plant uptake of soil nutrients and water. However, exogenous H₂O₂ inhibits the gravitropic growth of pea primary roots. It has been shown that CaCl₂ application can alleviate H₂O₂ inhibition, but the exact alleviation mechanism is not clear. Therefore, the present study was carried out by combining the transcriptome and metabolome with a view to investigate in depth the mechanism of action of exogenous CaCl₂ to alleviate the inhibition of pea primordial root gravitropism by H₂O₂. The results showed that the addition of CaCl₂ (10 mmol·L^-1) under H₂O₂ stress (150 mmol·L^-1) significantly increased the H₂
