“…A study using tobacco cultures treated with A. nodosum extracts revealed the same trend wherein the treated cultures showed significant levels of tolerance to freezing stress. This trait was attributed to the upregulation of key freezing tolerance genes such as galactinol synthase 2, pyrroline 5-carboxylate synthase, and acetyl-CoA carboxylase [ 126 ].…”

“…While the accumulation of proline was aided by the overexpression of the proline biosynthesis genes (5CS1 and P5CS2), as well as the downregulation of ProDH, a gene involved in proline breakdown. Furthermore, the same study also observed the upregulation of gene DGD1, which is involved in the production of galactolipid, which is known to have a role in cold stress tolerance [52].…”

“…Moreover, ANE treatment upregulated genes responsible for polysaccharide degradation ( 9SEX1 and SEX4 ) and carbohydrate biosynthesis ( GOLS2 and GOLS3 ), while downregulating genes involved in sucrose degradation. ANE treatment also induced key genes involved in freezing tolerance, including galactinol synthase 2, pyrroline 5-carboxylate synthase, and acetyl-CoA carboxylase ( Zamani-Babgohari et al., 2019 ; Ali et al., 2021 ). These findings provide compelling evidence supporting the role of ANE-based cryoprotectants in enhancing cellular stabilization in plants through molecular, biochemical, and physiological mechanisms.…”
