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: Two different androgenesis pathways, shed-microspore culture (SMC) and anther culture (AC), were developed for haploid induction in mutagenized M-1 rice cultivars. The effects of various factors on induction and regeneration phases were evaluated. The SMC method showed better results in terms of the number of regenerated embryos. Chromosome counting and flow cytometry analysis confirmed the presence of haploid plants, providing a valuable foundation for rice breeding research.

Summary: The age of seedlings and cultivation method have significant effects on the quality and yield of sweet pepper seedlings. The 60-day-old seedlings, whether sown directly or transplanted, showed better growth characteristics compared to the 50- and 40-day-old seedlings. The highest content of dry matter was found in the leaves of 60-day-old seedlings grown by transplanting. Higher yields were achieved by planting 60-day-old seedlings directly in cups in the greenhouse.

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: 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: 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 used microsatellite (SSR) markers to investigate the genetic status of 12 Bulgarian autochthonous sheep breeds. A total of 600 individuals from 50 flocks were analyzed, and 228 alleles were found. The results showed low differentiation between the breeds, with two breeds being the most distinct and the remaining breeds showing poor breed differentiation. Proper management strategies and breeding policies are needed to avoid intermixing of breeds and preserve breed purity.

Summary: Soil salinity, caused by climate change and rising temperatures, poses a serious threat to global food security. Breeding improved crop varieties is a potential solution to overcome salt stress. In this study, a collection of garden pea accessions was screened for salt tolerance under in vitro conditions. The results showed that many pea genotypes were able to tolerate 50 mM NaCl concentration, but higher salt levels significantly reduced germination and plant growth. Some genotypes were identified as highly sensitive, while others showed more tolerance. Overall, the study highlights the sensitivity of garden pea to salt stress and the importance of identifying tolerant accessions.
