Summary: This study focuses on a nuclear-targeted effector Pi07586 released by the highly destructive plant oomycete pathogen Phytophthora infestans. It is found that Pi07586 can effectively suppress plant immunity by inhibiting the expression of specific genes and reducing the levels of plant hormones. These findings enhance our understanding of the intricate relationship between P. infestans and host plants and shed new light on plant immune modulation.

Summary: Cyprus, located in the Mediterranean, relies on potato production as a significant source of agricultural revenue. During a late blight epidemic period, the population structure of Phytophthora infestans shifted towards A2 dominance, with reduced sensitivity to the fungicide mefenoxam. The high prevalence of the mefenoxam-insensitive EU_13_A2 lineage suggests the need for updated disease management strategies.

Summary: This study evaluated the resistance to late blight in 508 potato accessions and identified novel sources of resistance in wild potato species and landraces endemic to South America. The study also found that altitude and bioclimatic variables cannot predict the resistance level in these accessions. Furthermore, there is a high risk of genetic erosion in potato biodiversity in the Andes due to susceptibility to late blight in native landraces.

Summary: The study developed target-specific RNA interference molecules for late blight, along with nanoclay carriers, which effectively reduced infection when sprayed on plants. By targeting specific genes and using multigene targeted dsRNA-nanoclay, the plants showed enhanced disease resistance, reduced sporulation, and symptom expression. The use of nanoclay with multigene targeted dsRNA was effective in delivering and enhancing RNAi as a spray-induced gene silencing approach, showing potential as an environmentally friendly alternative to chemical fungicides for late blight protection.

Summary: Density functional theory (DFT) was used to investigate the stable structures and adsorption energy of Zr-n (n = 2-5) clusters with a single water molecule. The results showed a clear linear relationship between the adsorption energy and energy gaps of the clusters. Reaction path calculations revealed that the water molecule can react with the clusters to form Zr n O (n = 2-5), releasing hydrogen in exothermic reactions. Among the clusters, Zr-4 exhibited the highest reactivity with the water molecule. Natural population analysis (NPA) and density of states (DOS) provided insight into the hydrogen production and orbital properties, suggesting further reactivity of Zr n O (n = 2-5) with additional water molecules. This study enhances the understanding of Zr's chemical reactivity and its potential for catalysis and hydrogen production.

Summary: This study investigates the low-frequency variability of global vegetation and its connection to climate modes. The results show that the variability in vegetation greenness during the growing season is largely influenced by ENSO-d, PDO, and AMO climate modes, which have played a significant role in the greening of the Earth over the past decades.

Summary: As a new method, the instrumented sharp indentation technique is proposed for obtaining the surface residual stress of metallic materials. It is simple to use, applicable in-situ, and allows for measurements in the nano-to-macro range. The unified equivalent material indentation (UEMI) model is established to measure both equi-biaxial and uniaxial residual stresses within metallic structural materials. Only five parameters need to be calibrated via finite element analysis (FEA) in this model. The novel model is successfully verified using simulated materials from FEA and experimental data from seven metallic materials found in the references, showing good agreement with the pre-applied residual stress.

Summary: The climate system of the Third Pole region is highly sensitive to global warming, and mesoscale convective systems (MCSs) play a vital role in this system. The impact of MCSs on precipitation and flood risk in the downstream regions is significant, but there are methodological and regional differences in studying MCSs. By using a common framework, we can understand the characteristics, mechanisms, and impact of MCSs on seasonal and extreme precipitation in the region, and address knowledge gaps, such as the feedback of MCSs to the climate system, the impact of changing climate on MCS characteristics, and the assessment of flood and drought risks associated with changes in MCS frequency and intensity.

Summary: Mountains are important water sources for downstream areas, and their water resources are highly sensitive to climate change. Glacier retreat is the main cause of depletion in mountain water resources, but the contribution rate of glacier changes to total water storage changes is unknown. Globally, glacial melting accounted for about 49% of total water storage decline during 2006-2015. The contribution ranges from -23% to 728% in mountain regions and -21% to 99% in watersheds of the Third Pole and surroundings.

Summary: The 11-year solar cycle has a significant impact on precipitation over the Tibetan Plateau, with increased precipitation in the central-southern region and decreased precipitation in the southeastern region. The solar maximum leads to surface warming over the Asian continent, causing an enhanced thermal contrast between the Tibetan Plateau and the Indian Ocean, which strengthens the Indian summer monsoon and increases precipitation over the central-southern Tibetan Plateau. Additionally, a negative Pacific Decadal Oscillation-like sea surface temperature pattern under the solar maximum results in decreased precipitation in the Yangtze River basin, southeastern Tibetan Plateau, and southern Japan.

Summary: This study selected Mainland Southeast Asia as the study area and investigated the changes in tropical cyclone characteristics and associated rainfall. It was found that cyclones originating from the Western North Pacific and the South China Sea had the greatest influence on rainfall in Southeast Asia, while those from the Bay of Bengal had a relatively small impact. Additionally, the total rainfall contributed by cyclones accounted for up to 47% of the annual extreme rainfall amount in Southeast Asia. The study also observed significant decreasing trends in rainfall in the southeast region and increasing trends in the northeast region.

Summary: Significant efforts should be made to minimize crop losses caused by pests and diseases, as this could help alleviate the global food supply constraints. This review focuses on conventional plant breeding, cisgenesis, pesticide-based disease management, economic implications of cultivating cisgenic crops, and potential environmental impacts. Specific attention is given to potatoes and apples, with resistances to Phytophthora infestans and Venturia inaequalis, respectively. Adopting cisgenic varieties can reduce pesticide usage, benefit farmers, and contribute to the European Green Deal target.

Summary: This study simulated precipitation, air temperature, snowfall, and lake-effect snow over the Tibetan Plateau using the WRF model and compared different physical parameterization schemes. The results showed that all schemes performed well in simulating precipitation and air temperature, but were less accurate in simulating lake-effect snow. Further improvements are needed for future modeling of lake-effect snow or other snow events.

Summary: This study investigates the impact of moisture transport and sources on precipitation stable isotopes (d(18)O and d-excess) in the central Himalayas using measurements from two stations and simulations from the dispersion model FLEXPART. The results suggest that evaporation over northeastern India and convective activities over the Bay of Bengal and Bangladesh region play important roles in the changes of isotopes in precipitation. Furthermore, the study observes a change in altitude effect in 2015, which is more significant than the temperature and precipitation amount effect.

Summary: The influence of atmospheric vapor pressure deficit (VPD) on plant photosynthesis is well recognized, but its interactions with air temperature and soil moisture hinder a complete understanding of its impact on vegetation production. By excluding interactive effects, this study reveals a diverging response of productivity to VPD in the Northern Hemisphere. The interactions between VPD and temperature/soil moisture not only offset the potential positive impact of warming on vegetation productivity, but also amplify the negative effect of soil drying. Notably, there is a pronounced shift in vegetation productivity's response to VPD in high-latitude ecosystems when VPD surpasses a threshold of 3.5 to 4.0 hectopascals.

Summary: Precipitation over the Tibetan Plateau is influenced by systems such as the Asian monsoons, the westerlies, and local circulations. The Indian monsoon, the westerlies, and local circulations are the main systems affecting precipitation over the entire Tibetan Plateau. The East Asian summer monsoon primarily affects the eastern Tibetan Plateau. The Indian monsoon has the greatest influence on precipitation in the southern and central grid cells, while the westerlies have the greatest influence on precipitation in the northern and western grid cells. Local circulations have the strongest influence on the central and eastern grid cells.
