Identification of TIFY gene family in walnut and analysis of its expression under abiotic stresses

BACKGROUND: Walnuts (Juglans regia L.) are known for their nutrient-rich nuts and are one of the important economic tree species in the world. However, due to global warming and soil salinization, walnuts suffer from various abiotic stresses. TIFY (TIF[F/Y]XG) proteins play an essential role in the...

description BACKGROUND: Walnuts (Juglans regia L.) are known for their nutrient-rich nuts and are one of the important economic tree species in the world. However, due to global warming and soil salinization, walnuts suffer from various abiotic stresses. TIFY (TIF[F/Y]XG) proteins play an essential role in the growth and development of plants, signal transduction, and stress response in plants. At present, although the TIFY gene family of a number of plants has been identified and studied, how TIFY takes part in stress tolerance remains obscure and many functions of TIFY require further investigation. RESULT: In this study, twenty-one TIFY transcription factors were identified in the walnut genome database, and they were divided into four subfamilies (TIFY, JAZ, ZML, and PPD) by bioinformatics analysis. Chromosome location revealed tandem duplication of some genes. Phylogenetic tree analysis showed JrTIFYs were closely related to the TIFY gene family of Arabidopsis thaliana (A. thaliana). qRT-PCR (quantitative real-time PCR) analysis revealed the TIFY genes have different expression patterns in ‘Qingxiang’ and ‘Xiangling’ walnut varieties under drought, heat, and salt stress. JAZ subfamily was more expressed in different abiotic stress than other subfamilies. The expressions of JrTIFY14 under heat and salt stress were significantly higher than those under drought stress. However, the expression of JrTIFYs was not significant in ‘Xiangling’. CONCLUSION: This study reveals the TIFY gene family plays an important role in walnuts facing abiotic stresses and provides a theoretical basis for walnut breeding. SUPPLEMENTARY INFORMATION: The online version contains supplementary material available at 10.1186/s12864-022-08416-9.
