Summary: In this study, green synthesis of iron nanoparticles was achieved using aqueous spinach extract. The nanoparticles were coated with spermine, resulting in a spherical structure. The coated nanoparticles showed increased surface charge and were found to enhance the activity of antioxidant enzymes and secondary metabolites under drought stress, indicating their potential for increasing plant resistance. Furthermore, the biocompatibility of the nanoparticles was confirmed, and their ability to protect DNA against degradation by DNase I and ultrasonic waves was demonstrated.

Summary: Sweet potato is a globally important staple that holds potential in addressing hunger and malnutrition. This study investigated the nutritional composition, biochemical reaction to drought stress, and correlation with root yield in sweet potato cultivars. Orange-fleshed cultivars exhibited higher concentrations of Fe, Zn, Mg, Ca, Mn, and dietary fiber, while cream-fleshed cultivars had higher starch and carbohydrate content. Drought stress significantly affected antioxidant enzymes, chlorophyll and proline concentrations, and C-13 discrimination, all of which showed significant correlations with root yield. Nitrate reductase, proline, and chlorophyll concentrations at 60 days after planting are recommended as screening methods for drought tolerance. The cultivars Bophelo and Ndou, which are gaining popularity, have superior nutritional value and can contribute to food security and addressing malnutrition.

Summary: This study investigates the effects of endogenous polyamines (PAs) on the antioxidant system in alfalfa under drought stress. It was found that high activity of arginine decarboxylase (ADC) and S-adenosylmethionine decarboxylase (SAMDC) promotes the conversion of putrescine (Put) to spermidine (Spd) and spermine (Spm), leading to increased accumulation of Spd and Spm and enhanced drought resistance in alfalfa.

Summary: This study characterized the changes in physiology and transcriptome of potatoes under drought stress after pretreatment with 24-epibrassinolide (EBR). The results showed that EBR pretreatment increased ABA content, photosynthetic capacity, and antioxidant enzyme activities, while decreasing intercellular CO2 concentration, relative conductivity, and reactive oxygen species. Transcriptome analysis revealed differentially expressed genes involved in plant hormone signal transduction, starch and sucrose metabolism, circadian rhythm, flavonoid biosynthesis, and carotenoid biosynthesis. These findings provide new insights into the mechanisms by which BRs enhance drought resistance in potatoes.

Summary: This research demonstrates the essential role of RBOH-dependent H2O2 in BR-induced cold tolerance in grape seedlings. BR application can enhance cold tolerance by maintaining higher antioxidases activities, osmoprotectant levels, and regulating phytohormone levels. Furthermore, exogenous BR treatment triggers the upregulation of key genes and the production of endogenous H2O2, which contribute to the improvement of cold tolerance.

Summary: This study investigated the resistance of six wheat varieties to Sitobion avenae and the accumulation of total phenolic and flavonoid content. Yongliang No.15 and Ganchun No.18 showed high resistance against S. avenae. The accumulation of total phenolic and flavonoid content was positively correlated with developmental duration and negatively correlated with weight gain and mean relative growth rate. The correlation between flavonoid and biological parameters was stronger than the correlation between total phenolic and biological parameters. These findings provide important insights for screening and improving aphid-resistant wheat varieties and contribute to our understanding of the resistance mechanism of wheat varieties against S. avenae.

Summary: Bacterial endosymbionts, such as Wolbachia and Rickettsia, play important roles in herbivorous insects by supplying nutrients, increasing survivorship and fecundity, protecting against pathogens and heat, and expanding the range of suitable food plants. Our study examined the spatial and temporal distribution of Wolbachia and Rickettsia in Bemisia tabaci, and found that their titers in eggs fluctuated in a w pattern and their location in the egg changed over time. These findings provide insights into the vertical transmission mechanism and distribution of bacterial endosymbionts in different tissues of the host.
