Summary: Mycorrhizal symbioses have a significant impact on plant performance and ecosystem dynamics. Plant mycorrhizal traits offer valuable insights into belowground functionality. This study explores the correlation between phylogenetics, environmental factors, and plant mycorrhizal traits using a plant phylogenetic mega-tree and high-resolution climatic and edaphic data layers. The findings suggest that plant mycorrhizal type is more phylogenetically conserved, while environmental variables play a larger role in determining mycorrhizal status.

Summary: A greenhouse pot experiment was conducted to investigate the effect of arbuscular mycorrhiza fungus and plant growth promoting rhizobacterium on maize growth and nutrient concentrations under different levels of boron. The results showed that shoot and root dry weights significantly decreased as boron levels increased. However, microbial inoculation, especially mycorrhization, increased plant growth at lower boron levels. Shoot and root dry weights were positively correlated with shoot phosphorus concentration and root colonization. At higher boron levels, root colonization significantly decreased and the concentrations of iron, copper, sodium, and zinc in shoots significantly increased. In conclusion, low boron application improved plant growth while high boron rates were toxic. Microbial inoculation had a more alleviative effect when the plant was exposed to excess boron.

Summary: Non-native plants experience less damage from herbivory compared to native plants, but they have weaker constitutive defenses and stronger induced defenses. The strength of constitutive defenses in non-natives is influenced by the intensity of herbivory, while induced defenses show the opposite trend. Additionally, investment in induced defenses is positively correlated with growth, which may contribute to increased competitive ability.

Summary: Nanomaterials have unique effects on plants, which can be explained on spatial and time scales. They modify the composition and structure of cell walls and membranes, promoting internalization. Effects of nanomaterials on plant growth and metabolism occur at the organ and organism levels. Nanomaterials also interact with beneficial ecological plant partners, with varied effects on different organisms. Understanding of the bidirectional relationship between plants and nanomaterials is of great relevance.

Summary: The study examined the effects of DCINA and BION on the interactions between Bremia lactucae and lettuce. The results showed that DCINA was more effective in reducing sporulation but might weaken existing resistance. The treatment with DCINA may also reduce Dm7 gene transcription through epigenetic mechanisms and enhance susceptibility to Botrytis cinerea.

Summary: Treating Norway spruce with methyl jasmonate can enhance the tree's resistance to pests and this resistance lasts for a long time. This study found that methyl jasmonate treatment induces a transient upregulation of genes associated with jasmonic acid, salicylic acid, and ethylene biosynthesis, while repressing genes related to growth in Norway spruce.

Summary: This research focuses on the epigenetic changes in tomato plants primed for pathogen resistance, showing that treatment with beta-aminobutyric acid (BABA) results in a significant reduction in global cytosine methylation, particularly in CHH sequence contexts. The differentially methylated regions (DMRs) identified mainly consist of hypomethylated CHH DMRs, which are enriched in gene promoters and DNA transposons. Genes overlapping with CHH DMRs are enriched for stress response-related gene ontology terms and promoters of genes differentially expressed in response to infection with Botrytis cinerea. However, the majority of primed genes do not contain DMRs and the overall distribution of methylated cytosines in primed genes is not affected by BABA treatment. Therefore, it is suggested that methylation may confer priming via in-trans regulation and/or by targeting a smaller group of regulatory genes controlling stress responses.

Summary: Selected b-amino acids can prime plants for resistance against diseases. This study identified mutated lines with impaired RBH-induced immunity in Arabidopsis thaliana, and found that LYSINE HISTIDINE TRANSPORTER 1 (LHT1) acts as the main transporter for RBH and BABA uptake and distribution. The study also revealed a tradeoff between IR and plant growth mediated by LHT1.

Summary: Bioherbicides are made of microorganisms or natural compounds and are used for weed control, but they face limitations in field conditions. Nanotechnology can help overcome these limitations by designing specific formulations and carriers that improve the deficiencies of natural compounds and microorganisms. Nanoformulations can improve the efficacy of bioherbicides, reduce the amount required, and target specific weeds while preserving the crop. However, considerations such as production cost, safety, and potential toxic effects should be taken into account when choosing materials and nanodevices.

Summary: Priming is a plant's ability to remember environmental stress and improve their response to recurring stress. Epigenetic modifications in DNA and histone proteins may carry short-term and long-term memory or mediate transgenerational effects in plants. New experimental tools allow scientists to manipulate epigenetic modifications in specific locations of the genome, enabling them to study the causality between these modifications and gene expression under stress. Combining site-directed epigenetic manipulation with specific promoters creates opportunities for studying and engineering spatiotemporal patterns of priming.

Summary: This article provides a quantitative overview of how scientists have studied the effects of nanomaterials on plants between 2009 and 2022. The analysis shows that cultivated crops and plant nutrients are the main focus, and nanomaterials generally have higher concentrations than traditional fertilizers and soil. However, the studies have relatively short time spans, limited attention to soil microorganisms, and few experiments conducted under field conditions. Therefore, establishing correlations between effects and experimental parameters is challenging. The article concludes by discussing the potential impact of nanomaterials on plant systems.
