The changes in the physiological indices of the TaH2B-7D-knock-down plants. a Relative water content; b rate of relative electrolyte leakage; c MDA content; d proline content. NS, non-stressed plants; DS, drought-stressed plants; BSMV0, negative control of the VIGS system; BSMVTaH2B-7D, TaH2B-7D-knock-down plants. Each bar shows the mean ± standard errors (SE) for three biological replicates
