Summary: Doubled haploid (DH) plant production, such as anther culture (AC), is a useful tool in modern rice breeding. This study compared the effects of different combinations of plant growth regulators on callus induction in rice, and identified the best combination for in vitro green plant production.

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.

Summary: The development and improvement of biotechnological tools have greatly contributed to the progress in barley breeding program. The use of doubled haploids has significantly shortened the cultivar development time and has been widely used in various genetic studies. However, challenges such as low efficiency and genotypic specificity still need to be addressed.

Summary: An efficient protocol for in vitro anther culture in rice breeding, especially for indica genotypes, was evaluated. Three different induction media (N6NDK, N(6)NDZ, Ali-1) and four plant regeneration media (mMSNBK1, MSNBK3, MSNBKZ1, MSNBKZ2) were tested to increase the efficiency of in vitro androgenesis. The production of calli and green plantlets varied among different genotypes and media combinations. Flow cytometric analyses showed that 51.89% of the acclimatized indica rice plantlets had undergone spontaneous chromosome doubling. The utilization of DH plants has been integrated into the Hungarian rice breeding program, and tetraploid lines offer potential for future research and breeding directions.

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: In this study, an effective protocol for inducing haploid poplar plants was established, resulting in the successful generation of 96 whole doubled haploid plant lines. The doubled haploid population exhibited significantly higher phenotypic variance compared to the half-sib progeny of the donor tree. Some of the homozygous lines showed excellent potential as model plants for genetic and breeding studies.

Summary: In this study, a DH population was generated using the AC method in rice breeding. Through single- and two-locus SD analysis, five segregation distortion loci (SDLs) potentially linked to anther culturability were identified. Among these, SDL5 exhibited an overrepresentation of alleles from the female parent, while SDL1.1, SDL1.2, SDL2, and SDL7 displayed an overrepresentation of alleles from the male parent. Additionally, six pairs of epistatic interactions (EPIs) that influenced two-locus SDs in the DH population were discovered. The findings provide insights into the genetic control of anther culturability in rice.

Summary: Extrusion as a densification process had a significant negative effect on all responses in SC-CO2 extracted red pepper oleoresin. Regardless of substrate pretreatment, the extraction yield and carotenoid yield were maximized at extreme conditions of 60 degrees C and 50 MPa. The extractable colour and antioxidant activity showed positive correlation, while oxidative index showed negative correlation with carotenoid content of SC-CO2 extracts.

Summary: This study reveals that the CaBBX20 gene plays a positive role in carotenoid synthesis in pepper fruit, and its silencing leads to a decrease in carotenoid content.

Summary: Globally, heavy metal pollution of soil has remained a problem for food security and human health. This study characterized the toxicity symptoms of different concentrations of nickel (Ni) on pepper seedlings. The results showed that excess Ni reduced growth and biomass production, affected gas exchange elements and pigment molecules, and disrupted photosystem function. Higher Ni concentrations increased antioxidant enzyme activity and metabolites, but decreased nitrogen, potassium, and phosphorus levels. The uptake of Ni was higher in roots than shoots. Ni concentrations equal to or greater than 30 mg L-1 had a detrimental impact on pepper seedlings.

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: Excessive selenium poses a potential environmental hazard to organisms. This study employed quantitative proteomics to investigate the phosphorylation of pepper in response to selenium treatment. Bioinformatic analysis revealed different pathways and motifs associated with upregulated and downregulated phosphorylated proteins. These findings contribute to our understanding of plant response mechanisms and resistance to selenium pollution.

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.
