Plants have large amounts of the late embryogenesis abundant protein (LEA) family of proteins, which is involved in osmotic regulation. The Korla Pear () is an uncommon pear species that thrives in Xinjiang and can survive below-freezing conditions. We found that the gene was more expressed after cold treatment by looking at the transcriptome data of the Korla Pear.

Fruit firmness is crucial for storability, making cultivating varieties with higher firmness a key target in tomato breeding. In recent years, tomato varieties primarily rely on hybridizing ripening mutants to produce F hybrids to enhance firmness. However, the undesirable traits introduced by these mutants often lead to a decline in the quality of the varieties.

Steroidal glycoalkaloids (SGAs) are specialized metabolites in Solanaceae that serve as defensive compounds and undergo significant compositional changes during fruit ripening. This study explored the roles of transcription factors SlNOR and SlNOR-like1 in SGAs biosynthesis during tomato fruit development. UPLC-MS/MS revealed dynamic changes in four major SGAs: tomatidine, β-tomatine, α-tomatine, and Esculeoside A.

Some members of the SELF PRUNING (SP) gene family have been shown to play critical roles in developmental processes and stress responses across a wide range of plant species. The study identifies 13 members that can be divided into three subfamilies based on evolutionary analysis. Cis-Acting element analysis of the promoter regions indicated the presence of numerous stress- and hormone-responsive elements in the SlSP family.

Tomato yellow leaf curl Guangdong virus (TYLCGdV), a monopartite begomovirus first identified in 2004, remains poorly characterised. In this study, we demonstrate that TYLCGdV associates with a betasatellite, TYLCGdB, and the βC1 protein encoded by TYLCGdB is essential for symptom development. We also explore the role of TYLCGdV C4 protein by generating a C4-deficient infectious clone (TYLCGdV), revealing a dynamic role for TYLCGdV C4.
