Summary: Mutations in the SRFR1 gene can reactivate plant immunity to pathogens while also increasing susceptibility to fungal pathogens. Translating research findings from Arabidopsis to tomato, the study concluded that SRFR1 functions as a conserved negative regulator to (hemi-) biotrophic pathogens and a positive regulator to necrotrophic pathogens.

Summary: This study investigates the defensive role of BcOPR3 in plants against pathogen invasion. The results showed that overexpression of BcOPR3 increased susceptibility to Pst DC3000 but enhanced resistance to B. cinerea in Arabidopsis. BcOPR3-silenced NHCC001 plants showed increased resistance to downy mildew by reducing hyphal density and spores of H. parasitica. Additionally, partly silenced NHCC001 plants were also resistant to B. cinerea, potentially due to a synergistic effect of JA and SA.

Summary: Microbial mutualists can modify host species ecology and evolution, affecting interactions with other microbial species. Recent research has found that inoculation of arbuscular mycorrhizal fungi (AMF) can reduce disease impact, particularly necrotrophic diseases. This effect may be mediated by AMF regulation of signaling pathways and plant nutritional status.

Summary: Plant diversity can influence the risk of plant disease, but it is the composition of plant communities that is the key factor. This study found that in mixed plant communities, the relative abundance of root-associated fungal pathogens increased in both host and non-host plant species. The composition of the plant community, specifically the presence of certain neighboring host species, had a significant impact on the abundance of the pathogens. The results suggest that below-ground disease risk depends on the interactions between plant species and their root-associated pathogens.

Summary: The transmission of seed-borne pathogens during seed germination is a major cause of crop diseases. However, the immune responses of germinating seeds to biotic invaders are poorly understood. This study used the Arabidopsis thaliana/Alternaria brassicicola patho-system to investigate the transcriptional responses of germinating seeds and young seedlings to infection by the necrotrophic fungus. The results revealed non-canonical immune responses in early germinating seeds compared to early seedling establishment stages.

Summary: This study investigates the impact of nitrogen enrichment on the phylogenetic structure of arbuscular mycorrhizal fungal (AMF) communities in plant roots. The results show that nitrogen addition and host identity significantly affect the phylogenetic dispersion of AMF, which is caused by changes in the abundance of different fungal genera. The study also reveals that nitrogen addition influences the dispersion of AMF through its effects on soil properties and the dissimilarity of plant community and soil environments.

Summary: As climate warms, the strength of microbial thermal acclimation and its effects on soil carbon feedback may be influenced by multiple environmental factors, including nitrogen concentration and soil acidity. This study found that under warming conditions, higher nitrogen enrichment reduced the mass-specific respiration rates in alpine permafrost soils. The strength of thermal acclimation was found to increase as nitrogen enrichment increased, but the pathways by which nitrogen affects acclimation can vary.

Summary: The rapid biodiversity losses of the Anthropocene have motivated ecologists to understand how biodiversity affects infectious diseases. Spatial scale is thought to moderate negative biodiversity-disease relationships (i.e., dilution effects) in zoonotic diseases, whereas evidence from plant communities for an effect of scale remains limited, especially at local scales where the mechanisms underlying dilution effects actually work. This study tested how spatial scale affects the direction and magnitude of biodiversity-disease relationships in a Tibetan alpine meadow, and found that dilution effects were stronger at smaller quadrat sizes.

Summary: Recent studies have shown that intraspecific trait variability contributes significantly to total trait variation. However, the role of intraspecific variability in ecosystem functions under global change is still unclear. In this study, we examined the effects of nitrogen addition and warming on the productivity of a Tibetan alpine meadow and found that both intra- and inter-specific functional changes influenced productivity. Specifically, plant height variation among species promoted niche complementarity, while individuals with larger leaf area exerted dominance effects. Warming directly reduced productivity and indirectly suppressed it through a decrease in leaf area. Our findings highlight the importance of plant intraspecific trait variability in maintaining ecosystem functions, particularly in the face of global change.

Summary: Precipitation is a key driver of plant phenology, and our meta-analysis of 63 manipulative experiments shows that early-season and late-season phenophases respond differently to precipitation changes. Increased precipitation leads to advanced early-season phenophases and delayed late-season phenophases, resulting in longer reproductive phases and growing seasons. Decreased precipitation, on the other hand, leads to delayed leaf out and advanced leaf colouring, shortening the length of the growing season. These responses are less pronounced in wetter regions and are influenced by the seasons when precipitation changes occur.

Summary: The aim of this study was to examine patterns and potential mechanisms underlying geographical variation in community-wide herbivory on the Qinghai-Tibetan Plateau. The results showed that the latitudinal gradient in community-wide herbivory was primarily mediated by intraspecific variation, which was correlated with soil nitrogen content.

Summary: Asymmetrical light competition and direct detrimental effect of nitrogen have been proposed as two main mechanisms driving species richness declines following nitrogen (N) addition. However, the responses of tall and short plant species to N addition have rarely been studied. In this study, we found that N addition reduced the number of short species but increased the number of tall species, indicating divergent trait responses between them.

Summary: The study investigates the separate and interactive roles of fungal/oomycete pathogens and nutrient fertilization on community temporal stability in an alpine meadow. Results show that fungal pathogen exclusion decreases community temporal stability mainly by decreasing species asynchrony, while fertilization reduces community temporal stability by decreasing species stability. There is no interaction between pathogen exclusion and nutrient fertilization. These effects are due to direct effects on plant biomass and not indirect effects through plant diversity.

Summary: Through a long-term nitrogen addition experiment, we found that nitrogen enrichment has different effects on the diversity of root-associated arbuscular mycorrhizal fungal (AMF) communities, which is related to changes in soil properties and/or host plant functional structure. Moreover, we found that plant height plays a crucial role in driving the response of AMF diversity to nitrogen enrichment.
