三酰甘油脂肪酶(TGLS)是参与三酰甘油分解代谢的主要酶。TGLS能降解与植物发育和非生物胁迫反应有关的长链脂肪酸甘油三酯。TGL基因的研究大多集中在植物的种子油代谢和生物燃料等方面，而对番茄TGL基因家族的全基因组鉴定和特征研究却很少。根据最新发表的番茄基因组注释ITAG4.0，共鉴定出129个SLTGL基因，并根据其结构特征将其分为5类。大多数SLTGL基因分布在12条染色体中的3条上。片段重复似乎是番茄TGL基因家族扩大的驱动力。启动子分析表明，SLTGLS的启动子含有多种逆境应答顺式元件，如ARE、LTR、MBS、WRE3和WUN基序。大多数SLTGL基因在低温和高温胁迫后表达受到抑制，而在干旱胁迫下被诱导表达，如SlTGLa9、SlTGLa6、SlTGLa25、SlTGLa26和SlTGLa13。这些结果为深入了解SLTGL基因家族的功能提供了有价值的信息，并为进一步研究番茄三酰甘油分解代谢与非生物胁迫反应之间的联系奠定了基础。
Triacylglycerol Lipases (TGLs) are the major enzymes involved in triacylglycerol catabolism. TGLs hydrolyze long-chain fatty acid triglycerides, which are involved in plant development and abiotic stress responses. Whereas most studies of TGLs have focused on seed oil metabolism and biofuel in plants, limited information is available regarding the genome-wide identification and characterization of the TGL gene family in tomato (Solanum lycopersicum L.). Based on the latest published tomato genome annotation ITAG4.0, 129 SlTGL genes were identified and classified into 5 categories according to their structural characteristics. Most SlTGL genes were distributed on 3 of 12 chromosomes. Segment duplication appeared to be the driving force underlying expansion of the TGL gene family in tomato. The promoter analysis revealed that the promoters of SlTGLs contained many stress responsiveness cis-elements, such as ARE, LTR, MBS, WRE3, and WUN-motifs. Expression of the majority of SlTGL genes was suppressed following exposure to chilling and heat, while it was induced under drought stress, such as SlTGLa9, SlTGLa6, SlTGLa25, SlTGLa26, and SlTGLa13. These results provide valuable insights into the roles of the SlTGL genes family and lay a foundation for further functional studies on the linkage between triacylglycerol catabolism and abiotic stress responses in tomato.
