Summary: Root-associated fungi play a role in determining the positive relationship between plant diversity and productivity in experimental grasslands, and this relationship strengthens over time. Fungal diversity increases with plant diversity, but this relationship weakens over time, while fungal community composition becomes more closely associated with plant diversity. Pathogenic fungi have a stronger impact on the diversity-productivity relationship than other root-associated partners.

Summary: This study identified and characterized 22 defensin and defensin-like genes in chickpea. The genes were found to play a role in defense against fungal pathogens and interact with fungal plasma membrane components. The findings have important implications for identifying potential disease resistance genes in chickpea and their application in other crops.

Summary: The study found that warming plays a more important role than plant genotype in shaping the seasonal dynamics of the foliar fungal community on oak trees. As the season progresses, fungal species richness increases, evenness tends to decrease, and the community composition changes significantly.

Summary: Our study provides empirical evidence on the assembly, sources, interactions, and potential functions of wetland plant root microbial communities and their implications for future applications in the wetland ecosystem. We compared the bacterial and fungal communities in different niches of Typha orientalis at various wetland sites, and found that the microbial diversity, composition, and interaction networks are primarily influenced by compartment niche and developmental stage rather than wetland site. The root endosphere microbiomes of T. orientalis were found to be derived mainly from rhizosphere soil and water, and the assembly processes of bacterial and fungal communities were driven by deterministic and stochastic processes, respectively. The microbial interaction network and keystone taxa varied at different developmental stages, and the functional prediction data supported the distribution pattern of bacterial and fungal microbiomes.

Summary: Chickpea production is susceptible to drought stress. A genetic region called 'QTL-hotspot' has been identified to control chickpea growth and improve crop production under drought. A non-synonymous substitution in the CaTIFY4b transcription factor has been found to regulate seed weight and organ size in chickpea, and ectopic expression of CaTIFY4b in a different plant species enhances root growth under water deficit. Gene expression analysis suggests that CaTIFY4b may regulate organ size under water deficit by modulating the expression of a transcriptional co-activator called GIF1. These findings provide new insights into the physiological and molecular mechanisms of chickpea growth and production under specific drought conditions.

Summary: Understanding the succession patterns of microbial community along root growth provides insights into the interaction between roots and microbes. The study found apparent differences in anatomical traits among different growth stages of fine roots, with bacterial and fungal communities showing distinct succession patterns. Additionally, the fine roots growth has shaped the composition and structure of root-associated bacterial and fungal communities.

Summary: Studies have shown the importance of positive interactions between genotypes in wild plant species, influenced by kin selection theory and the elbow-room hypothesis. However, there are shortcomings in existing research, such as a lack of reliable estimates of genetic relatedness among genotypes and ecological characterization of natural habitats. A combination of evolutionary ecology and genomics is proposed to establish the eco-genomic landscape of positive genotype-by-genotype interactions in wild plant species.

Summary: Cassava is a widely cultivated food that plays a significant role in the socioeconomics of developing countries. However, fungal spoilage can negatively impact its productivity and quality, and pose a risk of mycotoxin contamination. This study investigated the diversity of fungal communities in Brazilian cassava samples and identified several potentially toxigenic species. Constant monitoring of cassava products and soil is crucial due to the importance of fungal contamination.

Summary: Forest fungal communities in Xishuangbanna, China are influenced by soil environment, root morphological traits, and root chemistry. Results showed that soil phosphorus is the main factor affecting root-associated fungal communities, while root calcium and manganese concentrations and root morphology also play a secondary role.

Summary: The effect of plant communities on nitrogen cycling and N2O fluxes under flooding conditions was investigated. Mixing grasses with legumes reduced nitrogen losses and enhanced plant nitrogen uptake in flooded conditions. However, the presence of legumes increased N2O fluxes due to increased soil nitrate availability.

Summary: This study examined the plasticity of root system architecture (RSA) traits in eight bottle gourd genotypes from different geographical origins and found that increased root diameter and volume may be a response to water deficit. The Chilean genotypes had the highest water productivity, and the Illapel and Chepica genotypes showed higher root diameter, root volume, and water productivity under water-deficit conditions. These genotypes may be promising drought-tolerant candidates for breeding programs.

Summary: Microbial communities are influenced by a complex system of host effects, with variation of host control within species governed by many small-effect genes. These host impacts seem targeted on particular microbial species, and there is no evidence yet that interactions differ between fungal and bacterial communities or among different compartments of the plant.

Summary: Commercial formulations of beneficial microbes have been used to enrich the rhizosphere microbiome of tomato plants and enhance their resistance against soil-borne parasites and herbivores. A mixture containing plant growth-promoting rhizobacteria, opportunistic biocontrol fungi, and arbuscular mycorrhizal fungi was found to be more effective in limiting pest damage compared to a formulation containing only arbuscular mycorrhizal fungi. The colonization of plant roots by beneficial fungi stimulated the plant immune system and reduced the activities of defense-supporting enzymes, leading to enhanced resistance against nematodes. The addition of certain chemicals abolished the repressive effect of the beneficial microbe mixture on nematode infection. When exposed to water stress, the treated plants showed improved resistance and maintained higher numbers of developed individuals in the roots compared to untreated stressed plants.

Summary: The study optimized chickpea aquafaba production and drying methods to produce standardized aquafaba powder. The results showed that both freeze-dried and spray-dried aquafaba can retain their functionality following rehydration. This indicates the potential for dried aquafaba to mimic egg functions in food emulsions and produce a wide range of eggless food products.

Summary: In this study, the relationship between heat tolerance and the regulation of HSP and ABA hormones was investigated in Canadian pea varieties. The transcription of HSP genes and the accumulation of ABA were upregulated under heat stress. Heat-tolerant varieties showed higher ABA synthesis and turnover rate at 3 hours of heat stress.

Summary: This study compared the genetic variation of 14 alfalfa populations from long-term grazing sites with alfalfa cultivars released between 1926 and 1980. The results showed that the alfalfa populations from long-term grazing sites had varying levels of genetic variation and originated from different subspecies. Genetic variations in forage dry matter yield, spring vigor, and plant height were low, but genetic variations in regrowth, fall plant height, days to flower, and crude protein were still high.

Summary: The study shows that fungal inoculants can improve wheat growth and phosphorus uptake in organically managed soil, and enhance lentil growth and phosphorus uptake in conventionally managed soil. However, co-application of two inoculants does not have a clear advantage, and carry-over effects are inconsistent.
