ABSTRACT
Although soluble silicate was reported to accelerate wound healing in muskmelon fruit through encouraging the deposition of lignin or free fatty acids, whether sodium silicate affects the biosynthesis, cross-linking and transport of suberin monomers during potato wound healing remains unknown. In this study, sodium silicate upregulated the expression and activity of 4-coumarate coenzyme A ligase (4CL), phenylalanine ammonia lyase (PAL), and promoted the synthesis of phenolic acids (caffeic acid, p-coumaric acid, cinnamic acid, sinapic acid, and ferulic acid) in tuber wounds. Meanwhile, sodium silicate upregulated the expression of glycerol-3-phosphate acyltransferase (StGPAT), fatty acyl reductase (StFAR), long-chain acyl-CoA synthetase (StLACS), ß-ketoacyl-CoA synthase (StKCS), and cytochrome P450 (StCYP86A33), and thus increased the levels of α, ω-diacids, ω-hydroxy acids, and primary alcohols in wounds. Sodium silicate also induced the expression of ω-hydroxy acid/fatty alcohol hydroxycinnamoyl transferase (StFHT), ABC transporter (StABCG), and promoted the deposition of suberin in wound surface, hence reducing tuber disease index and weight loss during healing. Taken together, sodium silicate may accelerate suberin accumulation at potato tubers wound through inducing the phenylpropanoid pathway and fatty acid metabolism.
