LzSCL9, a Novel GRAS Transcription Factor in Lanzhou Lily (Lilium davidii var. unicolor), Participates in Regulation of Trichokonins-Primed Heat Stress Tolerance
In our previous research, we found that trichokonins' (TKs) employment improved the thermotolerance of the Lanzhou lily, a renowned edible crop species endemic to China that is relatively susceptible to high temperatures (HTs). Here, a novel Lanzhou lily GRAS gene, <i>LzSCL9</i>, was identified to respond to heat stress (HS) and HS+TKs treatment based on transcriptome and RT-qPCR analysis. TKs could improve the upregulation of <i>LzSCL9</i> during long-term HS. The expression profile of <i>LzSCL9</i> in response to HS with or without TKs treatment showed a significant positive correlation with <i>LzHsfA2a-1</i>, which was previously identified as a key regulator in TKs' conferred resilience to HT. More importantly, overexpression of <i>LzSCL9</i> in the lily enhanced its tolerance to HTs and silencing <i>LzSCL9</i> in the lily reduced heat resistance. Taken together, this study identified the positive role of LzSCL9 in TK-induced thermotolerance, thereby preliminarily establishing a molecular mechanism on TKs regulating the thermostability of the Lanzhou lily and providing a new candidate regulator for plant heat-resistant breeding.
