Summary: This study demonstrates that nitric oxide (NO) plays a crucial role in restoring iron (Fe) deficiency-induced growth inhibition and oxidative stress in alfalfa. By upregulating specific genes, NO helps alleviate the negative effects of Fe deficiency by inhibiting oxidative stress and enhancing antioxidant defense mechanisms.

Summary: Due to iron chlorosis, pear trees are greatly affected by iron deficiency, leading to significant losses every year. Traditional laboratory methods for determining iron content in leaves are time-consuming and labor-intensive, and do not accurately capture the physiological state of iron-deficient leaves. This paper proposes a micro-Raman spectral imaging method that offers a non-destructive, rapid, and precise visualization of iron-deficiency-related metabolites in pear leaves.

Summary: Plants require iron for chlorophyll synthesis, and lack of iron can lead to interveinal yellowing of growing leaves. Iron is absorbed by roots as Fe-MAs and transported to growing leaves via phloem, but the mechanisms of iron synthesis, transport, and utilization still require intensive investigation.

Summary: This study investigated the treatment effect of plant growth-promoting rhizobacterium Rahnella aquatilis JZ-GX1 on iron-deficient Cinnamomum camphora and analyzed its impact on soil microbial community and rhizosphere metabolism. The results showed that inoculation with JZ-GX1 significantly increased chlorophyll content, promoted active iron redistribution, and enhanced antioxidant enzyme activities in C. camphora, alleviating membrane damage caused by iron deficiency. JZ-GX1 also promoted iron absorption by secreting desferrioxamine (DFO) and increased the abundance of specific fungi in the rhizosphere soil.

Summary: The study showed that irrigation promoted the content of organic acids in sweet cherry fruits, but led to a decrease in hydroxycinnamic acids, flavonols, and flavanols in the leaves and fruits. The composition of phytochemicals in fruits, shoot length, and yield efficiency were influenced by rootstock and the presence of fruits.

Summary: Iron is essential for plant functions, but high-pH and calcareous soil can cause iron deficiency chlorosis (IDC) and yield losses in crops. By studying the genetic resources of mungbeans and conducting genetic and genomic analyses, researchers identified a candidate gene named VrYSL3 that is responsible for resistance to calcareous soil.

Summary: This review summarizes the potential effects of climate change on agricultural yield and micronutrient quality of plant foods, as well as the availability of animal foods. The study suggests that climate change is likely to affect the availability of micronutrient-rich foods, rather than their nutrient content. Mitigating and adaptive strategies should be considered to reduce the risk of micronutrient deficiencies in vulnerable populations.

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: Dramatic climate change and high light conditions in the Mediterranean area have negatively affected crop production. Salicylic acid (SA) has been found to protect photosystem II (PSII) from phototoxicity. This study investigated the mechanism by which SA improves PSII efficiency in oregano seedlings under moderate drought stress (MoDS). The results showed that SA improved PSII efficiency by increasing the fraction of open PSII reaction centers and the efficiency of these open reaction centers, resulting in an enhanced electron transport rate. SA application under MoDS optimized antenna size and enhanced the effective quantum yield of PSII photochemistry through increased efficiency of the oxygen evolving complex and the fraction of open PSII reaction centers.

Summary: The study aims to understand how peach and nectarine tree varieties respond to winter and spring temperatures and evaluate the effectiveness of different chill and heat accumulation models in predicting bloom dates under various climatic conditions. The researchers analyzed data from 14 cultivars grown in 11 European locations and found significant variations in chill accumulation and rest completion among sites. They also observed that bloom timing is strongly influenced by delayed rest completion and heat accumulation. The Dynamic Model showed better predictions of bloom dates compared to other models. However, further research is needed to improve the reliability of climatic requirements for peach cultivars and provide guidance for adapting peach production to changing climate conditions.

Summary: Plant proteins that lack classical signal peptide leader sequences, known as leaderless secretory proteins (LSPs), play roles in plant development and stress responses. Identifying LSPs in plant proteomics experiments is challenging due to possible contamination during purification, and machine learning algorithms also lack sufficient validated examples. This study establishes criteria for identifying potential plant LSPs based on experimental observations and trains random forest classifiers to predict LSPs. The resulting database LSPDB and bioinformatic prediction tools LSPpred and SPLpred provide a method for predicting and identifying plant putative LSPs until more validated LSPs are established.

Summary: Iron is an essential micronutrient for plants and is usually limited in calcareous soils. This study investigates the effects of the auxin-precursor IAOx on iron deficiency responses in Medicago truncatula plants. The results show that exogenous IAOx promotes lateral roots growth, decreases chlorosis, and delays the decline in pH and increase in FCR activity and flavins in iron-deficient plants. Gene expression levels are consistent with the physiological responses, suggesting that IAOx plays an active role in iron homeostasis.

Summary: In this study, 17 apple accessions were harvested and stored in a cold room for six months to evaluate the differences in biochemical levels between harvest and long-term cold storage. The performance of different accessions was assessed based on fruit quality parameters, antioxidant compounds, sugars, and organic acids. Triploid accessions with russeting showed higher content of bio-active compounds after cold storage, but also experienced cell damages and increased chilling injuries. Spanish accessions and non-Spanish bred cultivars demonstrated suitability for long-term cold storage without chilling injuries. The study highlights the importance of considering native accessions and non-Spanish cultivars in future breeding programs.

Summary: This study evaluated the impact of melatonin (MT) application on photosynthesis in mint plants. The results showed that MT increased chlorophyll content and improved light energy capture, leading to enhanced photosystem II (PSII) quantum yield and electron transport rate. However, high concentrations of MT reduced the efficiency of the oxygen-evolving complex, causing photoinhibition and increased reactive oxygen species (ROS) production. MT induced stomatal closure through ROS production, resulting in decreased excitation pressure at PSII and improved efficiency. The non-photochemical quenching mechanism also contributed to the enhancement of photosynthesis by MT. These findings suggest that MT can be used as a biostimulant to enhance crop yields under both stressed and non-stressed conditions.

Summary: The influence of different Prunus rootstocks on the chilling injury susceptibility and biochemical characteristics of 'Big Top' nectarine fruits was investigated. The results showed that the choice of rootstocks significantly affected the leatheriness and bleeding symptoms, firmness, acidity, sugar and organic acid content, as well as enzymatic activities. Parameters such as sugars, organic acids, phenolic compounds, and enzymatic activities were found to be important in preventing chilling injury susceptibility.
