Maize Phosphorus Leaf Deficiency (MPLD) Database 224x224
<p>Monitoring the nutritional status of crops is crucial to assessing high productivity, optimizing cost, and minimizing environmental impact. Given that nutritional deficiencies primarily manifest through visual characteristics, artificial vision stands out as a competitive choice to assess the nutritional status of individual plants.</p><p>However, in order to train a supervised artificial vision system driven by convolutional neural networks (CNNs), a high amount of data, properly formatted and labeled is necessary. This work presents a curated image database to study single-nutrient deficiencies, specifically, phosphorus deficiency in maize leaves, named Maize Phosphorus Leaf Deficiency (MPLD) Database.</p><p>This database is composed of <strong>20892 </strong>samples of maize leaves placed on a withe background. Images are <strong>224x224</strong> pixels size, representing three levels of phosphorus deficiency: complete absence of the nutrient (labeled -P), half dose of the required phosphorus for normal plant development (-P50), and complete supply (C). </p>
Phosphorus nutrition strategies in a symbiodiniacean species: Implications in coral-alga symbiosis facing increasing phosphorus deficiency in future warmer oceans
<p><span>Coral reefs thrive in the oligotrophic ocean and rely on symbiotic algae to acquire nutrients. </span><span>Global warming is projected to intensify surface ocean nutrient deficiency and anthropogenic discharge of wastes with high nitrogen (N): phosphorus (P) ratios can exacerbate P nutrient limitation. However, our understanding on how symbiotic algae cope with P deficiency is limited. Here, we </span><span>investigated the responses of a coral symbiotic species of <em>Symbiodiniaceae, Cladocopium goreaui</em>, to P-limitation by examining its physiological performance and transcriptomic profile. </span><span>Under P stress, <em>C. goreaui</em> exhibited decreases in algal growth, photosynthetic efficiency, and cellular P content but enhancement in carbon fixation, N assimilation, N:P ratio, and energy metabolism, with downregulated expression of carbohydrate exporter genes. Besides, <em>C. goreaui </em>showed flexible mechanisms of utilizing different dissolved organic phosphorus to relieve P deficiency. When provided glycerol phosphate,<em> C. goreaui</em> hydrolyzed it extracellularly to produce phosphate for uptake. When grown on phytate, in contrast, <em>C. goreaui</em> upregulated the endocytosis pathway while no dissolved inorganic phosphorus was released into the medium, suggesting that phytate was transported into the cell, potentially via the endocytosis pathway. This study sheds light on the survival strategies of <em>C. goreaui</em> and potential weakening of its role as an organic carbon supplier in P-limited environments, underscoring the importance of more systematic investigation on future projections of such effects.</span></p>
