Despite extensive research highlighting the pivotal role of MYB transcription factors in regulating anthocyanin biosynthesis, the interactive regulatory network involving these MYB factors in pear fruits remains inadequately characterized. In this study, the anthocyanin-regulatory gene was successfully cloned from 'Yuluxiang' pear () fruits, and its influence on anthocyanin accumulation was confirmed through transient expression assays. Specifically, the co-transformation of with its partner in pears served to validate the functional role of . Subsequently, PbrMYB114 was employed as bait in a yeast two-hybrid screening assay, using a 'Yuluxiang' pear protein library, which led to the identification of 25 interacting proteins. Further validation of the interactions between PbrMYB114 and PbrMT2/PbrMT3 was conducted. Investigations into the role of and in 'Duli' seedlings () revealed their potential to enhance anthocyanin accumulation. The outcomes of these studies provide novel insights into the protein network that regulates pear anthocyanin biosynthesis, particularly the functional interactions among PbrMYB114 and associated proteins.

Article Synopsis
- Hybrid crops show better yields and resilience, but the genes behind hybrid vigor (heterosis) are not well understood, making breeding predictions difficult.
- Researchers created detailed genomes of two pear hybrids, 'Yuluxiang' and 'Hongxiangsu,' to study gene expression differences and develop a pangenome graph for pears.
- They identified nearly 6000 genes with allele-specific expression related to fruit quality traits, highlighting the significance of certain genes like Ma1 in determining acid levels in fruit, offering insights into how these genes contribute to hybrid advantages.
Preservative effects of flower flavonoids on fresh-cut Yuluxiang pear.

flower flavonoids (OFFF) possess superior antioxidant and antibacterial activities. However, scant information exists on the efficacy of these secondary metabolites as preservatives for fresh-cut fruits and vegetables. Here, OFFF were tested as a natural preservative for the first time in fresh-cut Yuluxiang pear ( Rehd.

Melatonin (MT), an indoleamine compound, has a pleiotropic effect on plant growth and development and can regulate the quality of tree fruit. Systematic research on the effect of preharvest MT spraying on pear fruit quality and technical solutions for MT application to regulate pear fruit quality are still lacking. Thus, here we aimed to evaluate the effects of different spraying times, concentrations, and exogenous MT application times on 'Yuluxiang' pear fruit quality.

Hybrid breeding is the most important means of selecting pear () varieties, but a long juvenile period severely restricts the selection of new varieties. In this study, we used 'Yuluxiang' × 'Akituki' 4-year-old seedling trees to study the effects of plant growth regulators, ring stripping, and ring cutting on the promotion of phase change and flowering to assist in shortening the breeding cycle. A single application of 100 mg/kg 6-BA + 1000 mg/kg PP333 was most effective in promoting phase change and flowering.
