Deskripsi

The TUBBY gene family is a group of transcription factors found in animals and plants with many functions. <i>TLP</i> genes have a significant role in response to different abiotic stresses. However, there is limited knowledge regarding the TUBBY gene family in <i>T. aestivum</i>. Here we identified 40 <i>TaTLP</i> genes in wheat to reveal their potential function. This study found that TUBBY (<i>TaTLP</i>) genes are highly conserved in wheat. The GO analysis of <i>TaTLP</i> genes revealed their role in growth and stress responses. Promoter analysis revealed that most <i>TaTLPs</i> participate in hormone and abiotic stress responses. The heatmap analysis also showed that <i>TaTLP</i> genes showed expression under various hormonal and abiotic stress conditions. Several genes were upregulated under different hormonal and temperature stresses. The qRT-PCR analysis confirmed our hypotheses. The results clearly indicate that various <i>TaTLP</i> genes showed high expression under temperature stress conditions. Furthermore, the results showed that <i>TaTLP</i> genes are expressed in multiple tissues with different expression patterns. For the first time in wheat, we present a comprehensive <i>TaTLP</i> analysis. These findings provide valuable clues for future research about the role of <i>TLPs</i> in the abiotic stress process in plants. Overall, the research outcomes can serve as a model for improving wheat quality through genetic engineering.
