Special Issue Information

Dear Colleagues,

Vegetables play a vital role in maintaining human health by providing a rich source of essential vitamins, fiber, minerals, and nutrients. The development of new vegetable varieties of a high quality and multiple resistances to biotic and abiotic stresses is becoming increasingly important, especially given the escalating environmental challenges and diverse market demands. To expedite breeding programs, it is crucial to incorporate molecular-marker-assisted and whole-genome selection technologies, which rely on the availability of vegetable genomes.

In recent years, advancements in sequencing technologies have significantly simplified genome assembly and reduced the associated costs. The formation of high-quality genomes has been achieved for most major crops, greatly facilitating functional genomics research and breeding efforts. However, many vegetables, particularly orphan crops, still lack reference-level genomes. Additionally, for some vegetables with published genomes, the existing assemblies fail to encompass the breeding backbone lines that are vital for practical breeding programs. Consequently, there is an ongoing need for genome assembly and data mining across various vegetable varieties and germplasms. Furthermore, the full potential of genome resources in enhancing the genetic breeding of vegetables has yet to be comprehensively explored.

In this upcoming Special Issue, entitled "Vegetable Genomes and Genetic Breeding", we invite submissions of research and review papers focusing on the aforementioned topics, as well as other areas related to genomic and genetic studies of vegetables. Through these contributions, we aim to enrich genomic resources and advance genetic breeding efforts in the field of vegetables

Abstract
Phosphorus is critical for plant growth but often becomes less accessible due to its precipitation with cations in soil. Fabaceae, a diverse plant family, exhibits robust adaptability and includes species like Lupinus albus, known for its efficient phosphorus utilization via cluster roots. [...] Read more.
Phosphorus is critical for plant growth but often becomes less accessible due to its precipitation with cations in soil. Fabaceae, a diverse plant family, exhibits robust adaptability and includes species like Lupinus albus, known for its efficient phosphorus utilization via cluster roots. Here, we systematically identified phosphorus-utilization-efficiency (PUE) gene families across 35 Fabaceae species, highlighting significant gene amplification in PUE pathways in Fabaceae. Different PUE pathways exhibited variable amplification, evolution, and retention patterns among various Fabaceae crops. Additionally, the number of homologous genes of the root hair development gene RSL2 in L. albus was far more than that in other Fabaceae species. Multiple copies of the RSL2 gene were amplified and retained in L. albus after whole genome triplication. The gene structure and motifs specifically retained in L. albus were different from homologous genes in other plants. Combining transcriptome analysis under low-phosphorus treatment, it was found that most of the homologous genes of RSL2 in L. albus showed high expression in the cluster roots, suggesting that the RSL2 gene family plays an important role in the adaptation process of L. albus to low-phosphorus environments and the formation of cluster roots.
