ABA Alleviates Uptake and Accumulation of Zinc in Grapevine (<i>Vitis vinifera</i> L.) by Inducing Expression of ZIP and Detoxification-Related Genes.

It is worth noticing that ABA treatment decreased SA in roots at 4 DAT compared with the Excess Zn treatment, even though the difference was only marginally significant ( P = 0.07), indicating that in the grapevine roots exposed to excess Zn, SA signaling could be negatively regulated by ABA as reported for the plant immune response ( de Torres Zabala et al., 2009 ; Kim et al., 2011 ).
