Summary: Gene co-expression networks are powerful tools for understanding functional interactions between genes. We present an algorithm to construct gene functional networks for genes annotated in a given biological process or other aspects of interest. The algorithm is based on the correlation of time expression profiles and ensures robustness by repeatedly finding gene expression relations in independent genotypes. Additionally, we propose an algorithm to identify transcription factor candidates for regulating hub genes within the network.

Summary: Five GPX genes were identified in the pepper genome, and they were unevenly distributed on the 12 chromosomes. These genes were found to contain highly conserved motifs and other conserved sequences. The promoter region of these genes also contained cis elements related to plant hormones and abiotic stress response.

Summary: In this study, seven CaNLP members were identified in peppers based on genome data, and two nitrogen transport elements were found in the CaNLP5 promoter. Phylogenetic analysis showed that pepper NLP and tomato NLP have the closest genetic relationship. The expression levels of CaNLP1, CaNLP3, and CaNLP4 were high in roots, stems, and leaves, while CaNLP7 expression was high during the color transformation of pepper fruit. These findings provide valuable insights into the roles of CaNLPs in regulating nitrate absorption and transport.

Summary: In this study, six PAO genes were identified in the pepper genome, and it was found that CaPAO2 and CaPAO4 were significantly upregulated under cold stress. Further experiments demonstrated that overexpression of CaPAO2 and CaPAO4 enhanced freezing-stress tolerance in plants. These findings provide candidate genes for breeding cold-stress-tolerant transgenic pepper cultivars.

Summary: As highly conserved signaling pathway modules, mitogen-activated protein kinase (MAPK) cascades play important roles in stress and hormonal responses in plants. In this study, 47 putative Raf-like kinase genes were isolated from the pepper genome and classified into two major categories, B and C. The transcriptional analysis revealed that subgroup B3, C2, C3, and C5 members were significantly induced by osmotic stress, indicating their functional association with osmotic stress response mediated via both ABA-dependent and ABA-independent pathways. These findings contribute to our understanding of the biological functions of CaRaf kinases in plant responses to abiotic stresses.

Summary: A severe fruit rot symptom was observed on green bell pepper in the local vegetable market in New Delhi, India. The pathogen causing the fruit rot was identified as Alternaria alternata and was found to be able to infect tomatoes and eggplant as well. These findings are important for developing suitable strategies for fruit rot management and postharvest handling.

Summary: This study investigated the role of the CaEXP4 gene in the cracking of pepper fruits. The results showed that fruit cracking was associated with changes in the levels of pectin, cellulose, lignin, and enzymatic activity. The analysis of differentially expressed genes during the fruit cracking process identified several pathways related to cell wall metabolism and lignin biosynthesis.

Summary: This study systematically analyzed the structure, conserved motifs, and expression patterns of the CaTIFY gene family in pepper. The results showed that CaTIFY genes are involved in plant stress responses, with CaTIFY7 and CaTIFY10b being significantly induced by cold stress. Overexpression of CaTIFY7 and CaTIFY10b enhanced cold tolerance in plants.

Summary: This study investigates the correlation between anthocyanin accumulation and antioxidant capacity in purple pepper berries during ripening. The results show a decreasing trend in polyphenolic and flavonoid content as well as antioxidant capacity as the maturity of the samples increases. Both genotype and phenophase have significant effects on phytonutrients, with the extreme purple pepper exhibiting the highest polyphenolic and flavonoid content, as well as antioxidant capacity.

Summary: Pepper, a widely cultivated vegetable crop, has significant uses in chemistry, medicine, and other industries besides being a condiment and food. Its fruits are rich in various pigments, which have important healthcare and economic value. Although progress has been made in understanding the color development of pepper fruits, the developmental mechanisms related to pigment biosynthesis and regulatory genes are still not fully understood. This review outlines the biosynthetic pathways of three important pigments in pepper and describes the genetics and molecular regulation mechanisms of different fruit colors. The aim of this review is to provide insights into the molecular mechanisms of pigment biosynthesis in pepper for future breeding of high-quality colored pepper varieties.

Summary: The origin and function of different types of invertase enzymes in land plants were investigated. Plastidic and mitochondrial invertases play roles in achieving high photosynthetic and respiratory rates, while cytosolic invertases are important for increasing carbon utilization efficiency. These invertases originated from ancestral genes in cyanobacteria and evolved through gene duplication and transfer processes.
