Special Issue Information

Dear Colleagues,

Vegetable crops provide humans with abundant and indispensable nutrients, such as vitamins, minerals, fibers and many health-promoting substances. Vegetable crops are also an important source of income for over 1.4 billion farmers around the world, and the harvesting area in 2019 has reached 596.9 million ha according to FAO statistics. However, the production of vegetable crops faces new challenges, such as population explosion and extreme weather conditions, and newly spreading diseases brought by global climate change. In addition, new requirements related to the yield, quality and resistance of the vegetable crops from the producer, consumer and market are put forward. How to meet the new challenges and requirements is a rising question. Fortunately, the genomic era now presents us with a new treasure chest with novel molecular genetics and genomics tools that enable us to solve the problem accurately and efficiently.

This Special Issue will focus on studies and advances concerning the molecular breeding of vegetable crops in the genomic era, including: (i) high-efficiency breeding technologies, such as high-throughput molecular-assisted selection and new generation of male sterility breeding systems; (ii) germplasm innovation technologies, such as molecular assisted distant hybridization and cross-species gene transformation; (iii) mining of important trait genes and their molecular mechanism related to yield, abiotic and biotic resistance, quality and nutrients, using multi-omics and molecular biological methods; (iv) genome design breeding, such as genome sequencing, foreground and background selection, gene editing, etc. We invite researchers to submit papers that highlight the above fields, and reviews summarizing past works and bringing new insights and opinions will also be welcome.

In recent years, quantitative trait loci (QTL) mapping approaches have been widely implemented to identify genomic regions affecting variation for different traits for marker-assisted selection (MAS). Meta-QTL analysis for different traits in chile peppers (Capsicum spp.) remains lacking, and therefore it would be necessary to re-evaluate identified QTL for a more precise MAS for genetic improvement. We report the first known meta-QTL analysis for diverse traits in the chile pepper QTLome. A literature survey using 29 published linkage mapping studies identified 766 individual QTL from five different trait classes. A total of 311 QTL were projected into a consensus map. Meta-analysis identified 30 meta-QTL regions distributed across the 12 chromosomes of Capsicum. MQTL5.1 and MQTL5.2 related to Phytophthora capsici fruit and root rot resistance were delimited to < 1.0 cM confidence intervals in chromosome P5. Candidate gene analysis for the P5 meta-QTL revealed functions related to histone methylation and demethylation, indicating the potential role of epigenetics for P. capsici resistance. Allele-specific markers for the meta-QTL will be developed and validated for MAS of P. capsici resistant lines. Altogether, results from meta-QTL analysis for chile pepper QTLome rendered further insights into the genetic architecture of different traits for this valuable horticultural crop. Full article
