    Recently, the Strawberry Research Laboratory of the Institute of Forestry and Fruits, Beijing Academy of Agriculture and Forestry Sciences published an online publication entitled "Genome-wide identification, characterization, forbid ex" in the international mainstream academic journal International Journal of Molecular Sciences (IF=6.
    208/Q1).
    pression analysis of tubby-like protein (TLP) gene family members in woodland strawberry (Fragaria vesca)
    ".
    Through a systematic analysis of the strawberry FvTLP gene family, this study revealed the evolutionary pattern of the FvTLP gene family and its function
    in the abiotic stress response.
     
    Since strawberries are susceptible to abiotic stress such as high temperature, low temperature, drought, and high salt during the growth and development process, it is of great significance
    for strawberry stress resistance breeding to mine stress resistance genes and analyze the abiotic stress response mechanism of strawberries.
    In this study, the strawberry stress resistance-related gene TLP was screened and analyzed, and through the analysis of the family structure and evolutionary analysis of the FvTLP gene, it was found that the evolutionary pattern of the strawberry TLP family was different from
    the evolution model of the TLP family in other plants.
    The results of protein interaction analysis showed that FvTLPs could bind to FvSKP1 to form the E3 ubiquitin ligase complex, SCF complex, which functioned by regulating the degradation of target
    proteins.
    Through gene expression analysis and transgene verification, it is shown that FvTLPs are widely involved in abiotic stress responses such as salinity, drought, high and low temperature, and participate in the regulation of
    strawberry growth and development.
    This study lays a foundation
    for the analysis of the abiotic stress response mechanism and the exploration of TLP function in strawberries.
