Summary: The seedless mutant tn-1 in chili pepper is caused by a mutation in CaCKI1, which encodes histidine kinase involved in female gametophyte development. An amino acid insertion in the receiver domain of CaCKI1 may be the mutation responsible for tn-1.

Summary: This study adapted the WOFOST model to quantify the dry matter production of chili pepper and analyze the effects of fertilizer management, climate, and soil conditions on its yield. The results showed that the model performed well in simulating the growth dynamics of chili pepper and provided insights on the yield-nutrient interactions. These findings are significant for the cultivation and fertilization strategies of chili pepper.

Summary: Tobacco mosaic virus is a major threat to chili pepper production, and current management methods are limited. This study found that the use of TiO2 nanoparticles can reduce symptoms, decrease viral load, and improve morphological characteristics in pepper plants infected with tobacco mosaic virus, suggesting a novel control method.

Summary: This study compared the differences in secondary metabolism during chili pepper fruit development between wild and domesticated varieties, and found that trait selection affects the metabolism of chili pepper fruit development. It was also observed that there may be a heterosis effect in the F1 progeny.

Summary: This study identified new genomic regions associated with domestication traits in chili peppers, including fruit shape, seedlessness, and growth habit. These findings contribute to the understanding of the genetic basis of Capsicum domestication and can guide strategies for the conservation and improvement of genetic resources.

Summary: Photosynthesis is a crucial process supporting life on Earth, but unfavorable environmental conditions and toxic metals may limit its efficiency in plants, with genotypes showing varying responses. This study evaluated the photosynthetic parameters of different chili pepper varieties exposed to cadmium (Cd), thallium (Tl), and vanadium (V), and found that these metals could either inhibit or stimulate photosynthetic parameters depending on the genotype and dosage.

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: We report the genome sequence of Capsicum annuum 'Takanotsume', a popular Japanese chili pepper landrace, obtained through long-read sequencing and optical mapping. The genome assembly consists of 12 pseudomolecules, covering 97.0% of the estimated genome size, and predicts 34,324 high-confidence genes. Comparative genomics analysis reveals nucleotide sequence and genome structure variations between 'Takanotsume' and related Capsicum species. This genome sequence data will accelerate pan-genomics and breeding of Capsicum, and facilitate the study of genetic mechanisms underlying important traits of 'Takanotsume'.

Summary: A new seedless mutant, tn-1, was discovered in sweet pepper breeding, offering potential benefits for processing and consumption. Genetic analysis revealed that seedlessness is controlled by a single recessive gene, with the mutant serving as a useful breeding material for developing seedless sweet pepper.

Summary: This study analyzed the transcriptome of two pepper recombinant lines with different fruit weights, revealing differentially expressed genes and mechanisms controlling fruit weight. The findings showed that certain genes, such as Boron transporter 4 and genes in the Auxin signal transduction pathway, were highly expressed in the large-fruited pepper but reduced in the small-fruited pepper. Transcription factors, including CaMADS3, were also found to be highly differentially expressed in the large-fruited pepper. Weighted gene co-expression network analysis identified a module highly correlated with fruit weight. Overall, the study suggests that interactions between transcription factors and phytohormones may regulate the development of fruit size in peppers.

Summary: In the process of bell pepper (Capsicum annuum) fruit ripening, the conversion from chloroplasts to chromoplasts involves significant changes in the levels of various enzymes, including maintenance of high levels of specific complexes and enzymes, an increase in enzymes related to heterotrophic plastid metabolism, and a shift in abundance of enzymes related to chlorophyll catabolism and carotenoid biosynthesis. Despite these changes, certain proteins remain constant, suggesting a unique metabolic pathway in non-climacteric fruits like bell pepper.

Summary: This study provides a comprehensive overview of viromes in 15 major pepper cultivars through RNA sequencing. Bean broad wilt virus 2 (BBWV2) and cucumber mosaic virus (CMV) were identified as the major viruses infecting pepper plants, with different cultivars showing variations in virus infection and symptoms.
