Summary: Plants are susceptible to attack by pathogens and also experience iron deficiency. They have developed strategies to address iron deficiency, including rhizosphere acidification and iron reduction, as well as iron chelation. There is a cross-talk between pathogenic defense and iron uptake, as the production and secretion of antimicrobial molecules increase in response to iron deficiency, and phytohormones that induce pathogen-resistant genes also modulate genes related to iron uptake. Iron deficiency also induces the expression of defense-related genes.

Summary: There is a growing recognition of the regulatory role played by long non-coding RNAs (lncRNAs) in various cellular processes in eukaryotes. Recent research suggests that lncRNAs may also be involved in the postharvest biological processes of fruits and vegetables. This article provides an overview of the current state of lncRNAs, including their classification, identification, and potential involvement in postharvest senescence, quality maintenance, and stress tolerance in horticultural crops.

Summary: All species can adapt to their environment and exhibit physiological and pathological changes in response to stress. Plants adapt to their environment through generations of exposure to various elements and can enhance their ability to deal with stress through priming mechanisms. Priming relies on multiple mechanisms, including the expression of non-coding RNAs, DNA methylation, and histone modifications.

Summary: Genome editing tools are being widely used to improve crop resistance and quality, particularly in tomatoes. Researchers have successfully manipulated many genes to enhance tomato tolerance to abiotic stresses. The genome editing technologies, such as CRISPR/Cas9, are considered fast and efficient for crop improvement.

Summary: Aboveground, large and higher trophic-level organisms often respond more strongly to environmental changes than small and lower trophic-level organisms. However, whether this trophic or size-dependent sensitivity also applies to the most abundant animals, microscopic soil-borne nematodes, remains largely unknown. Here, we sampled an altitudinal transect across the Tibetan Plateau and applied a community-weighted mean (CWM) approach to test how differences in climatic and edaphic properties affect nematode CWM biomass at the level of community, trophic group and taxon mean biomass within trophic groups. We found that climatic and edaphic properties, particularly soil water-related properties, positively affected nematode CWM biomass, with no overall impact of altitude on nematode CWM biomass. Higher trophic-level omnivorous and predatory nematodes responded more strongly to climatic and edaphic properties, particularly to temperature, soil pH, and soil water content than lower trophic-level bacterivorous and fungivorous nematodes. However, these differences were likely not (only) driven by size, as we did not observe significant interactions between climatic and edaphic properties and mean biomasses within trophic groups. Together, our research implies a stronger, size-independent trophic sensitivity of higher trophic-level nematodes compared with lower trophic-level ones. Therefore, our findings provide new insights into the mechanisms underlying nematode body size structure in alpine grasslands and highlight that traits independent of size need to be found to explain increased sensitivity of higher trophic-level nematodes to climatic and edaphic properties, which might affect soil functioning.

Summary: LF-SOM accumulation and decomposition varied in response to N addition at different levels over 2 and 5 years. Organic compounds in LF-SOM showed high sensitivity but varying resistance to N levels in the 2nd and 5th year. Abiotic and biotic factors played different roles in driving LF-SOM transformation between the two years.

Summary: The excessive use of chemical fertilizers due to population growth and food demand has negatively affected soil fertility. In response, scientists have turned to plant growth-promoting rhizobacteria (PGPR) for sustainable farming. These bacteria release volatile organic compounds (VOCs) that enhance plant growth and defense mechanisms.

Summary: 2-Amino-3-methylhexanoic acid (AMHA) is a naturally occurring endogenous amino acid with the ability to enhance plant resistance against extreme temperature stresses, as well as fungal, bacterial, and viral diseases. It has the potential to become a unique natural elicitor for plant protection against biotic and abiotic stresses.
