Article Abstract
Little is known about how microbial communities shape the expression of plant phenotypes and phenotypic correlations. This is precisely the question that O'Brien et al. addressed using populations of highland teosinte, a wild relative of maize. The authors find that both abiotic conditions and different rhizosphere compositions have a strong effect on teosinte phenotypes and correlations among traits. These results indicate that microbial communities might have a strong effect on plant trait expression.

Increasing evidence indicates that the loss of soil microbial α-diversity triggered by environmental stress negatively impacts microbial functions; however, the effects of microbial α-diversity on community functions under environmental stress are poorly understood. Here, we investigated the changes in bacterial and fungal α- diversity along gradients of five natural stressors (temperature, precipitation, plant diversity, soil organic C and pH) across 45 grasslands in China and evaluated their connection with microbial functional traits. By quantifying the five environmental stresses into an integrated stress index, we found that the bacterial and fungal α-diversity declined under high environmental stress across three soil layers (0-20 cm, 20-40 cm and 40-60 cm).

Droughts are increasing with climate change, affecting the functioning of terrestrial ecosystems and limiting their capacity to mitigate rising atmospheric CO levels. However, there is still large uncertainty on the long-term impacts of drought on ecosystem carbon (C) cycling, and how this determines the effect of subsequent droughts. Here, we aimed to quantify how drought legacy affects the response of a heathland ecosystem to a subsequent drought for two life stages of Calluna vulgaris resulting from different mowing regimes.

Cancer is a multifaceted disease driven by a complex interplay of genetic predisposition, environmental factors and lifestyle habits. With the accelerating pace of cancer research, the gut microbiome has emerged as a critical modulator of human health and immunity. Disruption in the gut microbial populations and diversity, known as dysbiosis, has been linked with the development of chronic inflammation, oncogenesis, angiogenesis and metastasis.

Background: People living with HIV(PLWH) are a high-risk population for cancer. We conducted a pioneering study on the gut microbiota of PLWH with various types of cancer, revealing key microbiota.
Methods: We collected stool samples from 54 PLWH who have cancer (PLWH-C), including Kaposi's sarcoma (KS, n=7), lymphoma (L, n=22), lung cancer (LC, n=12), and colorectal cancer (CRC, n=13), 55 PLWH who do not have cancer (PLWH-NC), and 49 people living without HIV (Ctrl).

In the last decades, immunotherapy has revolutionized cancer treatment. Despite its success, a significant number of patients fail to respond, and the underlying causes of ineffectiveness remain poorly understood. Factors such as nutritional status and body composition are emerging as key predictors of immunotherapy outcomes.
