Summary: Potato cyst nematodes (PCN) are economically important pests with a worldwide distribution in all temperate regions where potatoes are grown. Resistant varieties are key for effective management of PCN infestations, and recent advances in potato genomics have provided tools for rapidly mapping resistance genes and developing molecular markers.

Summary: High population densities of the potato cyst nematodes (PCN), G. pallida and G. rostochiensis, have significant negative effects on potato production. This study explores the use of an unmanned vehicle (UAV) in detecting and estimating the impact of different densities of G. pallida on potato cultivars. The results show a relationship between the nematode population density and the UAV indices, indicating the potential use of UAVs in detecting and managing PCN infestations.

Summary: The genetic diversity of potato breeding germplasm in the Nordic region was found to be low, and there is a close relationship between the breeding material and the germplasm from the genebank. Genotypes from outside the Nordic region should be employed for genetic hybridization.

Summary: The study showed that flesh color plays a key role in consumers' sensory and hedonic expectations, with Uruguayan consumers favoring traditional purple-skin sweet potatoes with orange flesh for positive sensory expectations. However, after tasting, flesh color does not seem to have a significant influence on consumer liking.

Summary: CRISPR drive is a powerful tool for genetic manipulation and has potential applications in controlling pests and diseases in both animals and plants. In plant breeding, CRISPR drive can be used to disrupt susceptibility genes and develop pathogen-resistant cultivars. Further research and improvement are needed to fully utilize this technology and obtain homozygous mutant lines.

Summary: This review provides updated information on the impact of leaf rust on wheat production and productivity, as well as the research progress on resistance genes. It includes information on various Lr genes and other resistance genes, along with their association with known genes. The review also discusses the introgression/pyramiding of individual Lr genes in commercial/prominent cultivars from different countries and the challenges and future prospects of breeding for leaf rust resistance.

Summary: This study compares the effects of different potato cultivars on potato cyst nematode populations and finds that planting resistant cultivars can reduce nematode numbers and infection risk. Susceptible varieties lead to an increase in population density, while resistant varieties suppress nematode populations but do not eliminate them entirely.

Summary: Potato cultivars 'Calalo Gaspar' and 'Cruza 148' exhibit resistance to Ralstonia solanacearum infection, activating defense mechanisms such as chitin interactions, cell wall-related genes, and phenylpropanoid biosynthesis. In contrast, the susceptible cultivar 'Desiree' shows different defense mechanisms and hormone accumulation in response to Rs infection. These findings provide insights into the diverse responses of potato plants to Rs infection.

Summary: Developing varieties with diverse features, improving overall fruit quality, and quickly releasing them are difficult to achieve in conventional breeding. Genomics-assisted breeding can enhance breeding efficiency and help solve this breeding trilemma. Selecting new premium quality hybrids is possible by integrating genomics-assisted breeding technique.

Summary: Strawberry growers in California face challenges such as land prices, labor shortages, marketing standards, and low prices, which impact their cultivar selection. While disease resistant varieties show ecological promise, making them economically viable for growers is challenging. Support for grower revenues may be a promising policy avenue to encourage adoption of disease resistant varieties.

Summary: This article discusses the issue of violation of detailed balance in current quasiclassical methods for simulating nonadiabatic dynamics. By predicting the long-time limits of electronic populations using various quasiclassical mapping approaches, the severity of the problem is analyzed. The analysis confirms that regions of negative populations in the mapping space, introduced in most mapping approaches to go beyond the Ehrenfest approximation, present the most serious issue for reproducing correct thermalization behavior. Inverted potentials resulting from negative electronic populations entering the nuclear force can cause trajectories to accelerate off to infinity in an unphysical manner. The recently developed mapping approach to surface hopping (MASH) provides a solution by avoiding inverted potentials while accurately describing the dynamics.
