Summary: The comparative structural and functional analysis of chitin-binding lectins from S. tuberosum and S. lycopersicum revealed high percentages of proline residues and differences in binding affinity towards different chitin oligomers. The study showed that the binding of glycans significantly improved the structural stability of STL and SLL. These findings provide insights into the potential therapeutic properties of STL and SLL, laying the foundation for further experimental studies.

Summary: This study investigated the effect of compost and mineral fertilizer on soil fertility, potato yield, and residual effect on green beans production. The results showed that compost improved soil chemical properties and 20 t ha-1 of compost produced potato tubers with a diameter larger than 40 mm. Compost at 30 t ha-1 resulted in 5 t ha-1 additional green beans in the second year, while mineral fertilizer had no residual effect.

Summary: Researchers have found that the application of the carotenoid-derived metabolite beta-ionone (beta-I) causes a global reprogramming of gene expression in plants, resulting in enhanced resistance to the fungal pathogen Botrytis cinerea (B.c.). This discovery suggests the potential use of beta-I as an environmentally friendly bio-fungicide to control B.c. infestation.

Summary: Targeted gene silencing using small regulatory RNAs, such as artificial microRNAs and tasiRNAs, is a common technique in plant genetic studies. However, the study found that many existing methods resulted in poor small RNA processing, highlighting the need for further development in this field.

Summary: This study reported the characterization of 120 Alternaria isolates in Solanaceae plants, showing diversity and host-specific patterns which may have practical implications for establishing effective early blight genetic resistance and cultural management strategies, especially in tomato and potato crops.

Summary: This study investigated the impact of diet on the microbiome of M. persicae, finding significant changes in the bacterial community composition when aphids were transferred to different Solanaceae plants. Notably, there was a substantial increase in Pseudomonas abundance, especially under pepper plant diet. Additionally, negative effects on aphid population dynamics were observed when they were fed on pepper plants.

Summary: Populations and lineages of Phytophthora infestans can vary in their specificity to potato and tomato hosts. Specialists on one host may coexist with generalists on both hosts due to a trade-off between generalism and lesion growth rate. This study analyzed cross-inoculation trials on potato and tomato isolates, finding that higher specificity was associated with faster lesion growth on the original host at the population level. Tomato isolates tended to become more generalist over time. These findings provide insights into the coexistence of generalist and specialist strains and the potential exceptions to the trade-off.

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: Late blight caused by Phytophthora infestans is a major disease for tomato and potato production worldwide. This study characterized the P. infestans populations in Thailand using various techniques and found that tomato isolates are from the same lineage as those from 1994 to 2002, while potato populations have changed. The different responses to fungicides can be attributed to the use of metalaxyl, host preferences, and migration of new genotypes from infected potato seeds.

Summary: Cucumber mosaic virus (CMV) is a major concern for tomato and pepper growers in the Western region of Cameroon, causing loss in both quantity and quality of produce. This study used a serological method to detect CMV and describe its symptoms in infected tomato and pepper plants. The prevalence of CMV was found to be 37.22% in tomatoes and 78.33% in peppers. The study concludes that it is important to educate farmers about CMV and provide them with basic vector-management strategies.

Summary: The release of Tamarixia triozae has successfully established the parasitoid in New Zealand, with more than 30 release sites across the country. The presence of the parasitoid was confirmed in two regions over the three-year study, demonstrating its ability to survive over consecutive winters. The parasitoid was found to parasitize nymphs at multiple sites, indicating its potential to reduce potato psyllid populations.

Summary: This study compared the fitness components and Compound Biological Fitness Index (CBFI) of different mating types of P. infestans strains collected from central Mexico, and found that self-fertile strains were more fit in all fitness components. These results provide valuable information for the management and understanding of the evolutionary potential of this pathogen.

Summary: This paper discusses the resistance mechanisms to wilt caused by different bacteria in Solanaceous vegetables and introduces the molecular level analysis methods and research findings. The study finds that various molecular markers and metabolome analysis can reveal resistant genes and pathways, while genetic transformation can generate resistant lines. In addition, the paper analyzes the major QTLs for wilt resistance in tomato and chilli peppers and the conserved mechanisms.
