Summary: Apple scar skin viroid (ASSVd) can infect apple trees and cause scar skin symptoms. This study investigated the effects of ASSVd on apple tree growth, physiological characteristics, and leaf metabolome in young saplings. The results showed that ASSVd infection decreased leaf size, tree height, stem diameter, branch length, and leaf photosynthetic efficiency. It also affected the chlorophyll content and nutrient levels in the leaves. Metabolome analysis revealed changes in the abundance of metabolites related to isoflavonoid and phenylpropanoid biosynthesis, as well as carbohydrate and amino acid metabolism. These findings provide valuable insights into the physiological mechanisms underlying apple tree responses to ASSVd.

Summary: An agronomic itinerary for Se biofortification of two rice cultivars (Ariete and Ceres) through foliar fertilization with different concentrations of sodium selenate and sodium selenite was implemented in experimental fields. The Se enrichment in paddy grains was highest with selenite, especially at higher doses, and Zn was the most affected element by the Se treatments. The distribution of Se in the grains differed between the Ariete and Ceres cultivars, with Se favoring accumulation in the periphery of the grains in Ceres.

Summary: The study found significant differences in structure, photosynthetic activity, and protein expression profiles between bark and leaf chloroplasts in Salix matsudana. Bark chloroplasts exhibited lower grana stacks, higher starch levels, and lower oxygen evolution rates compared to leaf chloroplasts. Additionally, key proteins in photosynthesis light reactions were downregulated in bark chloroplasts, while proteins involved in dark reactions showed upregulation, suggesting a potential role of bark chloroplasts in fixing CO2 from malate decarboxylation.

Summary: The proteomic analysis of allotriploid poplar revealed elevated expression of proteins involved in photosynthesis, carbon fixation, sucrose, and starch accumulation, leading to increased biomass and growth advantage. Conversely, proteins related to sucrose decomposition, tricarboxylic acid cycle, and protein degradation showed significantly downregulated expression in allotriploids. This alternation in protein expression enhances the efficiency of key metabolic processes, ultimately resulting in the observed vegetative growth advantage and larger biomass in allotriploid poplar.

Summary: The excessive application of nitrogen fertilizer in Chinese apple production was found to decrease the content of soluble sugar and flavonoids in fruits, leading to poor fruit quality. High nitrogen levels also altered the nitrogen, carbon content, and C/N ratio of apple fruits. The study revealed that high nitrogen inhibited the accumulation of carbohydrates and flavonoids in fruits, and promoted the synthesis of amino acids using more carbon skeletons. This insight provides new understanding on the effects of high nitrogen on fruit quality.

Summary: This study compares the green and golden-yellow leaves of hybrid paper mulberry using physiological, cytological, and proteomic analyses. The mutants of hybrid paper mulberry exhibit golden-yellow leaves, reduced chlorophyll and carotenoid content, and increased flavonoid content. Cytological observations reveal defective chloroplasts in the mutants. Proteomic analysis identifies differentially accumulated proteins involved in chlorophyll synthesis, carotenoid metabolism, photosynthesis, and ribosome pathways, suggesting their role in adaptation to environmental conditions. This study provides insights into the formation mechanism of the golden-yellow leaf phenotype.

Summary: This study investigated the effect of calcium chloride (CaCl2) treatment on GABA accumulation in fresh-cut cantaloupe and the underlying mechanisms. The results showed that CaCl2 treatment increased GABA content and the activities of GAD and SSADH enzymes, while reducing glutamate content and GABA-T activity. Additionally, CaCl2 treatment upregulated the expressions of CmCML11 and CmCAMTA5, as well as several GABA shunt genes, through the transcriptional activation by CmCAMTA5. Furthermore, the interaction between CmCML11 and CmCAMTA5 enhanced the transcriptional activation of GABA shunt genes. Overall, this study reveals that CaCl2 treatment promotes GABA accumulation in fresh-cut cantaloupe through the combined effect of CmCML11 and CmCAMTA5 in regulating the expressions of GABA shunt genes.

Summary: Selenium (Se) can reduce uptake and translocation of cadmium (Cd) in plants by regulating root morphology. This study investigated the effects of Se(IV) on root exudates, root morphology, root endogenous hormones, and Cd uptake efficiency in rice under Cd stress. The results showed that Se(IV) significantly reduced Cd concentrations in shoots and roots, and decreased Cd uptake efficiency via root hairs. Se(IV) also affected root morphology, root exudates, and the synthesis of hormones like IAA and JA. However, transcriptome analysis revealed no upregulated differentially expressed genes (DEGs) in IAA synthesis.
