“…High Mn content leads to excess TE deposition in photosynthetic cells and might potentially impair cellular metabolism (Fernando et al, 2013), which may lead to metal toxicity in cells. High Mn content can decrease the net photosynthetic rate, stomatal conductance, internal carbon dioxide concentration and transpiration in several genotypes of cotton (Tavanti et al, 2019). The transpiration of plants depends not only on tree species physiology, i.e., the ability to regulate the stomatal aperture but also the leaf area.…”

“…The correlation analysis further demonstrated that both SPS and SS (synthesis direction) activities were significantly and positively correlated with sucrose content ( Figure 8 ); this finding is consistent with those of previous reports [ 37 , 38 ]. A study of cotton metabolism showed that increasing leaf sucrose and total sugar concentrations during Mn stress is a strategy for cotton plants to resist oxidative stress [ 39 ]. However, we found that the increase in sucrose synthesis may also be related to the reduction in NI activity.…”

Manganese deficiency critically impairs the function and stability of photosystem II (PSII) and negatively impacts crop growth and yield. However, the response mechanisms of carbon and nitrogen metabolism to Mn deficiency in different genotypes of maize and the differences in Mn deficiency tolerance are unclear. Herein, three different genotypes of maize seedlings (sensitive genotype: Mo17, tolerant genotype: B73, and B73 × Mo17) were exposed to Mn deficiency treatment for 16 days using liquid culture with different concentrations of MnSO4 [0.00, 2.23, 11.65, and 22.30 mg/L (control)]. We found that complete Mn deficiency significantly reduced maize seedling biomass; negatively affected the photosynthetic and chlorophyll fluorescence parameters; and depressed nitrate reductase, glutamine synthetase, and glutamate synthase activity. This resulted in reduced leaf and root nitrogen uptake, with Mo17 being most severely inhibited. B73 and B73 × Mo17 maintained higher sucrose phosphate synthase and sucrose synthase activities and lower neutral convertase activity compared to Mo17, which resulted in higher accumulation of soluble sugars and sucrose and maintenance of the osmoregulation capacity of leaves, which helped mitigate damage caused by Mn deficiency. The findings revealed the physiological regulation mechanism of carbon and nitrogen metabolism in different genotypes of maize seedlings that resist Mn deficiency stress, providing a theoretical basis for developing high yield and quality.

“…Adequate light enhances plant photosynthetic efficiency and boosts their growth rate. However, excessive sunshine hours can increase water evaporation rates, negatively impacting water availability to plants [52]. Additionally, excessively high sunshine hours may elevate surface temperatures, posing a threat to vegetation survival.…”

Vegetation cover in the Loess Plateau region is an important component of ecological protection in the Yellow River Basin, and this study provides a scientific reference for further vegetation restoration. Based on Landsat images and related data, we utilized the dimidiate pixel model and Geodetector method to study the vegetation cover in the Wuding River Basin from 2000 to 2022. The results indicated the spatial and temporal distribution of the vegetation cover and its changes over the study period. Additionally, the driving factors influencing its spatial changes were also uncovered. We also propose a land use shift vegetation cover contribution formula to quantify the effect of land type change on the FVC. The study showed that (1) the overall vegetation cover of the watershed increased significantly, and the FVC showed an increasing trend from 2000 to 2013 and a slow decline from 2013 to 2022, with the gradual transformation of low-graded FVC into a higher graded one. (2) The FVC increased spatially from northwest to southeast, and the trend of future changes is mainly decreasing. (3) The strongest explanatory power for the FVC change is the land use type and its interactive combination with rainfall. (4) The conversion of grassland to cropland contributes the most to the vegetation cover at 1.52%, and the increase in the cropland area is more conducive to the increase in the vegetation cover.
