Dear Colleagues,

The yield of horticultural crops is affected by the external environment, including biotic and abiotic stresses, and is also impacted by gene regulation and the endogenous phytohormones present in genetic characteristics. It is important that plant science analyze the environment and the genetic molecular regulation network of horticultural crop yield based on the new sequencing technologies, which are rapidly expanding our knowledge of the genome and epigenome of horticultural crops. Although academic researchers have made great contributions to the analysis of molecular regulatory network of model plants, the molecular mechanism of horticultural crop yield still requires further promotion. Therefore, there is an urgent need for gather information about how genetic and genomic data of crops, can lead to obtaining plants more adapted to consumers' and farmers' needs while pursuing a sustainable goal. These new technologies assist us not only in our understanding of the genome and epigenome of crops but also to modify the genome with an extraordinary precision to improve specific plant traits. Moreover, the advance in genetic engineering methods for crop transformation is also a growing field. In combination, these fields are becoming a powerful tool to improve crop varieties in a demanding changing environment. This Section plans to summarize the latest progress in the field of horticultural crop yield control and its application in different fields. We invite researchers to contribute studies, articles and reviews contributions to improve the molecular regulation and genetic improvement of horticultural crop yield.

Following topical collections within this section are currently open for submissions:

-Integrated analysis of genomics and transcriptomics data;

-Feature papers in gene regulation and metabolic engineering;

-Regulation of gene expression in horticultural crops;

-Plant tissue culture and transformation;

Research articles and reviews in this area of study are welcomed. We look forward to receiving your contributions.
