Summary: In this study, a detailed bioinformatics analysis of the Trihelix family in strawberries was performed, leading to the identification of 30 family members divided into five subfamilies. Gene expression experiments revealed the critical roles of Trihelix genes in disease resistance and hormonal signaling pathways in strawberries. Ectopic expression of FvTrihelix6 in Arabidopsis thaliana increased resistance against Colletotrichum.higginsianum infection. This study provides new insights and candidate genes for disease-resistance breeding of strawberries.

Summary: Soybean, as a main economic crop and a major source of oil and protein, is greatly affected by drought stress. This study explores the value of applying the GmDREB1 gene in improving the drought resistance of soybean. The results show that overexpression of GmDREB1 significantly enhances the drought resistance and yield of transgenic soybean. Mechanism analysis reveals that GmDREB1 regulates the expression of stress-related genes by interacting with ERF-like transcription factors, thus improving the drought resistance of transgenic soybean.

Summary: In this study, the role of SmERF73 in the regulation of tanshinone biosynthesis was investigated, showing that it activates the expression of tanshinone-related genes to increase tanshinone accumulation. SmERF73 and its targets are up-regulated by stress elicitors, with potential involvement in the jasmonic acid signaling pathway. This suggests a potential link between tanshinone production and plant stress responses.

Summary: Catharanthus roseus produces a variety of MIA metabolites in a heavily branched pathway, with gene expression being highly specific to cell type, organ, and stress. Further study of ORCA TFs reveals subfunctionalization in terms of regulating target genes and working synergistically with MYC2. Specific amino acid residues within ORCA DNA-binding domains play a role in regulating MIA pathway branches differently.

Summary: The trihelix gene family plays a crucial role in metabolic pathways and stress responses in plants. However, little is known about its distribution and functions in Melilotus albus, particularly in response to drought stress. In this study, 34 MaGTs were identified and characterized, and seven potential candidate genes for drought tolerance were identified. A key finding is the significant upregulation of MaGT17 in response to drought stress in both roots and shoots. These findings provide important insights into the molecular mechanisms and responses of trihelix proteins in M. albus.

Summary: The study identified a key transcription factor, PrASIL1, in tree peony seed oil accumulation, which represses oil accumulation by down-regulating numerous key genes during biosynthesis. Silencing the PrASIL1 gene led to up-regulation of oil biosynthesis genes and an increase in total lipids and major fatty acids. These findings provide new insights into controlling seed oil accumulation.

Summary: The present study identified proteins that interact with LaAP2L1 and revealed the regulatory mechanism of LaAP2L1 in the formation of fast-growing heterotic trait in Larix. Differentially expressed genes associated with LaAP2L1 overexpression were also identified, and they played important roles in regulatory processes such as cell component synthesis, gibbrellin metabolism, cell cycle phase transition, carbohydrate metabolism, and circadian rhythm regulation.

Summary: This study identified 135 AP2/ERF transcription factors in roses and explored their gene structure, phylogeny, and distribution. A novel DREB A2 subgroup gene, RcDREB2B, was isolated and characterized. Overexpression of RcDREB2B in roses led to altered sensitivity to salt, ABA, and PEG, affecting the expression of 12 osmotic and ABA-related genes.

Summary: The presence and action of growth signals, such as gibberellins, need to be coordinated with the availability of photo-assimilates for optimal plant growth performance. Disruption of factors like carbon availability, light and dark cues, and the circadian clock can lead to reduced levels of gibberellins and expression of downstream genes, impacting growth. Nighttime biosynthesis of bioactive GAs appears to be determined by the consumption of starch reserves, allowing for day-to-day adjustments of GA responses.
