Summary: This study investigated the responses and molecular characterization of genes in Fe-deficient sunflower plants. The results showed that Fe deficiency led to decreased plant biomass, photosynthetic efficiency, and concentrations of Fe and Zn in roots and shoots. Furthermore, it was observed that the expression of specific genes related to Fe and Zn uptake was affected by Fe shortage in sunflower plants.

Summary: In this study, transcriptome analysis was performed to investigate the crosstalk between copper excess and iron deficiency in rice. Several WRKY and bHLH family members were identified as potential transcription factors involved in copper detoxification and iron utilization regulation. The results indicate that copper excess induces iron deficiency response, while iron deficiency does not lead to copper toxicity response.

Summary: Enhanced root H+ efflux, regulated by H+-ATPase HA6, is crucial for iron deficiency tolerance in citrus. Transcription factor MYB308 activates HA6 expression and promotes iron uptake in iron-poor-soil-tolerant citrus species, while unable to do so in iron-poor-soil-sensitive citrus species due to sequence variation.

Summary: This study quantifies the uptake of iron in young citrus trees, its distribution among plant organs, and the contribution of iron absorbed from fertilizer to the development of new tissues. The results show that the root system accumulated over 90% of the total iron content in the plant, with iron-57 progressively enriching in different organs, especially in reproductive ones. Iron derived from fertilizer was preferentially supplied to young organs, but overall only represented a small percentage of the total iron content in the plant.

Summary: Immunological control of viral infections in the brain, especially through the TREM2 pathway, is crucial for protection against herpes simplex virus type 1 (HSV1) infection and maintenance of brain integrity. The down-regulation of TREM2 expression in HSV1-infected microglia leads to impaired antiviral response and decreased ability to phagocytose infected neurons. This study highlights the importance of TREM2 in the immune defense against viral infections and raises questions about its role in neurological pathologies.

Summary: The zinc-finger protein RZF1 is essential for magnesium uptake in roots and transport to shoots in rice plants. A rice mutant named LMGC1 was identified to have reduced magnesium content in leaves and increased magnesium content in roots. The gene OsRZF1, belonging to the RanBP2-type zinc-finger family, was found to be responsible for the low magnesium phenotype.

Summary: Iron is an essential element for plants, and their ability to acquire iron from low-iron solutions is not the sole determinant of tolerance to iron deficiency among barley genotypes. The live-autoradiography technique can help visualize the distribution of iron in plants and support phenotyping for nutrient transport.

Summary: This study revealed that nitrogen deficiency can lead to increased production of reactive oxygen species (ROS) and methylglyoxal (MG), but also enhances the ability of leaves and roots to detoxify these molecules. The effects of nitrogen deficiency on ROS and MG generation and their detoxification systems were found to be different in leaves and roots, with roots being more affected.

Summary: This study evaluated the tolerance of new citrus hybrid varieties to salt stress compared to Carrizo citrange. The results showed that some hybrids displayed severe growth inhibition and leaf damage under salt stress, while proline accumulation seemed to be a common response to salinization. Enhanced K+ uptake and transport rates were identified as key factors linked to improved salt tolerance in some genotypes.

Summary: This study evaluated the concentrations of macroelements in leaves and fruit under organic and conventional practices and found that management practices significantly affected the nutrient concentrations. The agronomic efficiency of macronutrients was higher in organic crops compared to conventional crops. The ratios of Ca and Mg and N/Ca and Ca/(K+Mg) were closely related to fruit quality attributes.

Summary: The cultivation and consumption of traditional lettuce varieties are increasing due to their diversity and high nutraceutical quality. However, lettuce is perishable, resulting in significant nutritional loss during storage. This study compared the variation of bioactive compounds, antioxidant capacity, and mineral content in landraces and commercial lettuce varieties during the storage period. The results showed individualized behavior among lettuce varieties, with no clear advantage for commercial varieties. Landrace L10 stood out for its stable appearance and nutritional quality throughout its life cycle.

Summary: Composting is an interesting option for recycling organic waste and mitigating environmental problems. This study evaluates the viability and optimization of industrial-scale composting using rice straw and sewage sludge. The composting process was characterized and temperature, organic carbon, nutrient and metal contents were monitored. The final composts showed suitable pH, high nitrogen content, and interesting macro- and micronutrient values. However, they also had certain salinity and high ammonium contents that should be considered for application in the field.
