Summary: The temporal and spatial heterogeneity of chlorophyll content and fluorescence in rice canopy leaves under different Cd stress concentrations was explored in this study. The responses of relative chlorophyll content (SPAD) and chlorophyll fluorescence (ChlF) parameters to Cd stress in different growth stages were analyzed. It was found that lower leaves had higher SPAD values in the tillering stage, while upper leaves had higher SPAD values in the heading and filling stages. Certain ChlF parameters were more sensitive to Cd stress than others.

Summary: Rice production is influenced by water and nitrogen management, and extreme rainfall leads to yield reduction. Optimizing water and nitrogen management can mitigate this reduction. A field experiment was conducted in a normal and wet year to explore suitable management practices. The results showed that increased nitrogen rate in a wet year improved rice nitrogen uptake and reduced the risk of yield reduction.

Summary: Highly oil-accumulative diatoms have potential as biomass for biofuel production. Understanding the relationship between oil accumulation and photosynthesis under fluctuating environmental conditions is crucial for high-yield diatom oil harvesting. In this study, the physiological responses of two diatom species (Fistulifera solaris and Mayamaea sp. JPCC CTDA0820) to nitrogen starvation were characterized, revealing distinct nitrogen requirements and photosynthetic responses. F. solaris exhibited growth retardation and suppressed photosynthetic activity, while Mayamaea sp. maintained normal growth and decreased Chl a amount per cells. These findings suggest two types of photosynthetic responses in oleaginous diatoms under nitrogen starvation.

Summary: Increasing nitrogen use efficiency in rice intensification (SRI) is crucial for achieving high crop yield and reducing nitrogen losses. This study aimed to determine the optimal leaf color chart (LCC) value for real-time nitrogen application in rice varieties under SRI. The results showed that an LCC value of 5 with 30 kg N/ha produced the highest grain yield and was effective in increasing nitrogen use efficiency and yield in rice. Additionally, using an LCC value of 5 with 20 kg N/ha also maintained high agronomic and recovery efficiency of nitrogen.

Summary: Plants produce various organic compounds during different growth phases, including primary and secondary metabolites. Secondary metabolites play important roles in plants' adaptation to changing environments and stress management. Plants also allocate some of their photosynthesized carbon as secondary metabolites to establish symbiotic relationships with soil microorganisms. It is crucial to identify specific metabolites that can distinguish beneficial and pathogenic microorganisms in the soil. A detailed understanding of the interactions between metabolite structures and beneficial microorganisms could have significant implications for ecology and agricultural research. Flavonoids are used as examples of secondary metabolites in this study to demonstrate recent advancements in controlling these valuable metabolites at different levels. Most of the research focuses on plant flavonoids, which protect the host plant against competitors or predators and have ecological implications. This review aims to summarize the wide range of functional and signaling activities of secondary metabolites, especially flavonoids, in the selective cross-talk between plants and their beneficial soil microbiome. Recent advances in understanding the interactions between plant species and their rhizosphere microbiomes through root exudates (flavonoids) are highlighted.

Summary: Rice is a staple food for billions of people and its bioavailability of iron and zinc is affected by phytic acid. A study found that while a genotype with high iron content had low bioavailability, possibly due to its high phytic acid content. Phytic acid mainly affects the bioavailability of iron, but has less effect on zinc, which is evenly distributed in the rice grain. The study also identified genes related to phytic acid synthesis and grain-specific phosphorus transporter genes that are expressed during grain filling and correlated with phytic acid accumulation. This research provides insights for breeders to develop rice genotypes with higher bioavailability of iron and zinc by targeting phytic acid related genes.

Summary: Rice is an ideal crop for improving nitrogen use efficiency (NUE), especially with urea fertilizer. However, there is limited research on contrasting rice genotypes for NUE. In this study, we compared the transcriptomes of low urea-responsive genotypes, Nidhi (low NUE) and Panvel1 (high NUE). Our findings showed differential expression of genes related to nutrient transporters, miRNAs, transcription factors, photosynthesis, water use efficiency, and post-translational modifications in high NUE rice. Furthermore, field evaluations demonstrated the superior agronomic performance of Panvel1, including grain yield and NUE. Our study also revealed common processes between urea-based and nitrate-based transcriptomes, suggesting the involvement of transporters and transcription factors in urea uptake and utilization for high NUE.

Summary: In cereals and legumes, phytic acid (PA) serves as a phosphorus reserve for growth and has both antioxidant activity and ability to bind minerals. Although it is considered an anti-nutritional factor due to its reduced bioavailability of minerals and proteins, PA has various health benefits including lowering the risk of diabetes and some cancers, improving heart health, and preventing kidney stone formation. Additionally, it has been found to be effective against foodborne bacteria. This paper provides an overview of phosphorus transport in plants, PA biosynthesis, its beneficial and anti-nutritional effects, and dephytinization methods.

This study evaluated 21 rice genotypes under drought conditions and identified several genotypes with higher drought tolerance and biomass production. These genotypes also showed higher grain yield and less reduction in grain filling percentage during the reproductive stage. Furthermore, the expression of certain genes in these genotypes supported their higher grain yield under drought stress.
