Special Issue Information

Dear Colleagues,

The Solanaceae family includes crops such as tomato, pepper, eggplant, potato, wolfberry, alkekengi, etc. Several crops in the Solanaceae family are very important foods or horticultural crops, widely consumed worldwide, as they are important sources of dietary compounds and several nutrients, including lycopene, capsaicinoids, anthocyanidin, vitamins A and C, minerals, and essential oils. Solanaceae crops, especially tomatoes and potatoes, are leading in horticultural research. Great progress has been achieved in genomics, gene editing technology, and haploidy breeding (potato). However, there are still a lot of unknown aspects that require investigating. Therefore, we aim to clarify Solanaceae crops' cultivation physiology, molecular biology and molecular breeding. Cultivation physiology includes photosynthesis, respiration, chlorophyll fluorescence, reactive oxygen species (ROS), enzyme activity, etc., of Solanaceae plants under open-field or protected cultivation conditions. Molecular biology regulates key genes, noncoding RNAs (miRNAs, circRNAs, and lncRNAs), DNA methylation, protein phosphorylation, etc., for growth and development, yield, quality, or biotic and abiotic stresses. Molecular breeding includes molecular marker-assisted breeding and genetic modification breeding. All of the abovementioned topics are within the scope of this Special Issue.

Phytochrome-interacting factor (PIF) is a subfamily of the basic helix–loop–helix (bHLH) transcription factors (TFs) and plays key roles in plant responses to diverse biotic and abiotic stresses. In this work, a PIF gene named CaPIF7a was cloned and its role in the regulation of pepper’s resistance to Phytophthora capsici infection (PCI) was studied. The cloned CaPIF7a gene has a CDS length of 1383 bp, encodes a hydrophilic protein containing bHLH and APB characteristic domains, and subcellular localization results showed that CaPIF7a was located in the nucleus. Expression analysis showed that CaPIF7a gene has the highest expression level in leaf, and its expression was regulated under PCI and salicylic acid (SA) treatment. Silencing of CaPIF7a in pepper plants by virus-induced gene silencing (VIGS) reduces the resistance of pepper to PCI, with decreased expression of SA-responsive and SA-biosynthesis genes and obviously decreased SA content. DNA affinity purification sequencing (DAP-seq) was employed to identify the potential targets of CaPIF7a, and yeast one-hybrid (Y1H) verified that CaPIF7a could regulate the expression of CaHY5 by binding its promoter. These findings indicated that CaPIF7a might be a key modulator in plant immune response and presented a possible regulatory network of CaPIF7a in PCI. Full article
