Special Issue Information

Dear Colleagues,

Horticultural plants generally include vegetables, fruit trees, tea trees, ornamental plants and medicinal plants. They are indispensable in people's daily lives.

Multi-omics techniques (such as chloroplast genomics, mitochondrial genomics, microbiomics, transcriptomics, genomics, proteomics, metabolomics and phenomics) play an increasingly important role in addressing fundamental issues related to the conservation and utilization of horticultural plants.

The chloroplast and mitochondrial genomes have become important tools for studying the evolution, species identification and genetic variation in horticultural plants. By analyzing the sequence and structural changes in the chloroplast and mitochondrial genomes, we can gain in-depth insights into the phylogenetic relationships among horticultural plant species, trace their origins and evolutionary processes, and provide valuable information for the genetic improvement and conservation of horticultural plant genetic resources.

The comprehensive analysis of genomics, proteomics, metabolomics and microbiomics data provides comprehensive biological information, helping us understand the genetic characteristics of horticultural plants, and the synthesis and regulatory mechanisms of bioactive compounds.

This Special Issue of Genes focuses on horticultural plant research from an omics perspective, and welcomes articles and reviews on the study of horticultural plants through multi-omics methods. The topics include, but are not limited to, the following: 1) identifying candidate stress resistance loci/genes in horticultural crops through omics data mining and other methods; 2) investigation of gene families related to horticultural plants, regulation of gene expression and validation of gene function using mutants and overexpression; and 3) analyzing the evolutionary process of horticultural plants through genomic data.

Leaves play a crucial role as ornamental organs in Spathiphyllum, exhibiting distinct differences across various Spathiphyllum varieties. Leaf development is intricately linked to processes of cell proliferation and expansion, with cell morphology often regulated by plant cell walls, primarily composed of cellulose. Alterations in cellulose content can impact cell morphology, subsequently influencing the overall shape of plant organs. Although cellulases have been shown to affect cellulose levels in plant cells, genetic evidence linking them to the regulation of leaf shape remains limited. This study took the leaves of Spathiphyllum ‘Mojo’ and its somatic variants as the research objects. We screened four cellulase gene family members from the transcriptome and then measured the leaf cellulose content, cellulase activity, and expression levels of cellulase-related genes. Correlation analysis pinpointed the gene SpGH9A3 as closely associated with leaf shape variations in the mutant. Green fluorescent fusion protein assays revealed that the SpGH9A3 protein was localized to the cell membrane. Notably, the expression of the SpGH9A3 gene in mutant leaves peaked during the early spread stage, resulting in smaller overall leaf size and reduced cellulose content upon overexpression in Arabidopsis.
