Evaluation of the expression pattern of TIAs pathway genes in response to tryptophan amino acid treatment and drought stress in Catharanthus roseus.

ABSTRACT: The leaves of the medicinal-ornamental plant Catharanthus roseus serve as the exclusive source of the anticancer alkaloids vinblastine and vincristine. The limited synthesis of these alkaloids, alongside efforts to enhance their production, has consistently been a focal point of research. Water scarcity, recognized as one of the most significant constraints in agriculture, has prompted this study to examine the effects of the amino acid elicitor tryptophan and drought stress on the alterations in secondary metabolites of C. roseus and the genes implicated in their biosynthetic pathways. This investigation was factorial experiment conducted within a completely randomized design (CRD) with three replications. The first factor involved drought stress (40% and 100% field capacity), the second
