Exploring Different Roles of <i>StWRKY4</i> and <i>StWRKY56</i> in Transgenic Potato Against Salt Stress.

ABSTRACT: WRKY transcription factors play an important role in transcriptional reprogramming associated with plant abiotic stress responses. In this study, the role of Solanum tuberosum (S. tuberosum; St) WRKY transcription factors StWRKY4 and StWRKY56 were explored in response to salt stress by generating transgenic potato lines using RNAi. The results showed that the total chlorophyll content in transgenic StWRKY4 was 6.1 mg/g at 200 mM after 35 days; however, in StWRKY56, an elevated 12.6 mg/g total chlorophyll was observed which indicated different operating mechanisms of these StWRKY transcription factors under salt stress. Proline content increased to 1.0 mg/g in StWRKY4 while it decreased to 0.54 mg/g in StWRKY56 as compare
