Summary: Marker-assisted backcrossing was used to introgress four blast-resistance genes (Piz, Pib, Pita, and Pik) into a susceptible japonica Italian rice variety, and an additional blast-resistance gene (Pita2/Ptr) was found, resulting in a total of five introgressed blast-resistance genes. Molecular analysis and phenotypic evaluations confirmed the broad-spectrum resistance of the developed lines. These blast-resistant japonica lines with multiple resistance genes will be valuable donors for future rice-breeding programs.

Summary: Developing multiple disease resistance in tomato through the stacking of naturally available host resistance alleles is a challenging yet rewarding area of research. In this study, we successfully applied marker assisted selection to identify superior segregants carrying three resistance alleles for leaf curl, root knot, and late blight disease, respectively. These segregants, derived from two diverse parents, have the potential to be valuable genetic resources for developing multiple disease resistance cultivars through rapid introgression of these genes.

Summary: Tomatoes are important vegetable crops, and genomics-assisted breeding shows great potential in this field. With the rapid development and cost reduction of sequencing technologies, as well as the use of high-throughput genotyping platforms and bioinformatics tools, the tomato genome has been decoded and extensively studied, providing valuable information for breeding programs. Genomics-assisted breeding has made progress in identifying genes and SNP markers associated with agronomic traits, and the genomic selection method is expected to improve breeding efficiency and genetic gain.

Summary: Analysis of autophagy-related genes in tomato identified SlATG18f's involvement in tomato leaf curl disease tolerance, with a CAPS marker developed as an effective tool for marker-assisted selection. Upregulation of SlATG18f was observed in tolerant cultivars subjected to virus infection, and gene silencing of SlATG18f in these cultivars led to disease susceptibility, suggesting its crucial role in tolerance. The study identified an SNP at -2916 upstream of the start codon in the gene sequence, and the developed CAPS marker showed significant association with tolerance characteristics in tomato germplasm.

Summary: Tomato yellow leaf curl disease caused by tomato yellow leaf curl virus has led to significant economic problems in tomato production worldwide. Breeding for host plant resistance, particularly by identifying and utilizing specific resistance genes, has been effective in controlling the disease. Additionally, the identification of novel sources of resistance in wild tomato species provides potential for broader and sustainable resistance to begomoviruses.

Summary: Tomato yellow leaf curl virus (TYLCV) is a highly harmful disease that affects tomato growth and production worldwide. Six resistance genes have been transferred to commercial tomato cultivars from wild germplasms, providing protection against TYLCV. However, only three of these resistance genes have shown significant levels of resistance. Researchers have cloned these resistance genes and studied their antiviral mechanisms, aiming to maintain and spread resistance to TYLCV globally.

Summary: Bacterial, fungal, and viral diseases of tomato are major causes of yield losses, especially in humid growing environments. Chromosome 11 of tomato contains genes that confer resistance to several prominent tomato pathogens. Marker-assisted selection and pedigree breeding strategy were used to combine these resistance genes into a linked cassette, which can be inherited in future crosses. The recombinant plants with combined resistance showed similar resistance levels to the controls, indicating the effectiveness of trait markers on chromosome 11 for selecting disease-resistant plants.

Summary: Micronutrient malnutrition is a serious threat to the developing world's human population, especially those relying on a cereal-based diet. Millets, as versatile crops, have the potential to address this issue due to their tolerance to abiotic stresses and rich nutritional characteristics. This review highlights recent genetic and genomic innovations in improving grain micronutrient density in millets, as well as advancements in high-throughput phenotyping and genetic diversity exploration. The integration of omics approaches, such as genomics and proteomics, can help develop nutrient-dense varieties for the future.

Summary: This paper proposes a new method for detecting lung tumors that combines a Gaussian filter with a hybrid Recurrent Neural Network-Generative Adversarial Network (RNN-GAN). The RNN-GAN architecture utilizes sequential data in lung tumor images, with the RNN component capturing temporal relationships and patterns and the GAN component creating synthetic tumor samples for improved training. Additionally, a Gaussian filter is applied to enhance image quality and facilitate precise feature extraction. The experimental findings demonstrate that the proposed hybrid RNN-GAN with the Gaussian filter achieves higher accuracy in lung tumor identification compared to conventional techniques.
