Climate change significantly alters the dynamics of plant pathogens, primarily through changes in temperature, humidity, and precipitation patterns, which can enhance the virulence and spread of various plant diseases. Indeed, the increased frequency of extreme weather events, which is a direct consequence of climate change, creates favorable conditions for outbreaks of plant diseases. As global temperatures rise, the geographic range of many plant pathogens is expanding, exposing new regions and species to diseases previously limited to warmer climates. Climate change not only affects the prevalence and severity of plant diseases but also influences the effectiveness of disease management strategies, necessitating adaptive approaches in agricultural practices. This review presents a thorough examination of the relationship between climate change and plant pathogens and carefully provides an analysis of the interplay between climatic shifts and disease dynamics.

Increasing photosynthetic efficiency in crops is a feasible strategy to enhance grain yield. Canopy photosynthesis, the integral of photosynthesis of all photosynthetic tissues of an entire plant canopy, is intrinsically linked to biomass production and crop yield and is influenced by both photosynthetic efficiency at the tissue level and canopy architecture, which determines the light environment at that tissue. This review summarizes current methodologies for measuring photosynthesis via gas exchange, fluorescence, and reflectance spectrum at the field, canopy, and leaf levels. Gas exchange techniques include eddy covariance, canopy gas exchange chambers, and organ-level gas exchange methods, which can measure CO<sub>2</sub> and H<sub>2</sub>O fluxes. Chlorophyll fluorescence methods include solar-induced fluorescence (SIF), laser-induced fluorescence transient (LIFT), pulse amplitude modulated (PAM) fluorescence, and light induced chlorophyll <em>a</em> fluorescence rise (OJIP transient), which can be used to evaluate photosynthetic efficiency and plant stress responses. One of the commonly used reflectance spectrum methods for studying photosynthesis is the hyperspectral reflectance technique, which can estimate photosynthesis-related traits. High-throughput crop photosynthesis phenotyping can be performed with different combinations of these techniques.

This study involved the cultivation of rainfed potatoes at three locations within the climatic transition zone of Northwest China. We employed stepwise linear regression and machine learning techniques to pinpoint the key environmental factors influencing potato tuber yield and the yield-precipitation relationship. The slope of the water-limited yield potential relationship for potatoes was determined to be 172.1 kg ha<sup>−1</sup> mm<sup>−1</sup>, with an intercept at 121.2 mm. The potato tuber yield exhibited an upward trend with increasing GSP but declined once the precipitation exceeded 400 mm. However, GSP alone explained up to 30% of the variability in potato tuber yield. Factors such as soil moisture at planting, maximum temperatures during the tuber stolon initiation and bulking stages, diurnal temperature fluctuations at maturity, and excessive precipitation events during the growing season significantly influenced potato tuber yield, and consequently, the relationship between yield and GSP. Conversely, climatic factors accounted for more than 63% of the variation in potato tuber yield, with the multiple linear regression model yielding the best results. This was especially evident when the yield-precipitation relationship was categorized into two groups based on the amount and distribution of GSP, maximum temperature, and radiation levels. This analysis suggested that preventing unnecessary water evaporation when precipitation is low, improving drainage when precipitation is high, and planting potato on an optimal date can advance potato production.</p></div>","PeriodicalId":100340,"journal":{"name":"Crop and Environment","volume":"3 2","pages":"Pages 112-122"},"PeriodicalIF":0.0,"publicationDate":"2024-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2773126X24000029/pdfft?md5=c9b986ee4fcc2b1ccae6e690fd884250&pid=1-s2.0-S2773126X24000029-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140464254","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
