Conditionally Significant eQTL and TWAS Analyses Identify MsRD26 as a Major Candidate Positive Regulator of Salt Tolerance in Medicago sativa L

open access: yesAdvanced Science, EarlyView.
Salt stress significantly impacts plant growth. Through population transcriptome, eQTL and TWAS analyses, we identified several candidate genes potentially associated with salt stress response. Functional assays suggested that some of these genes may contribute to salt tolerance.

Rainfall Shapes the Diversity of Soil Nitrogen‐Fixing Microorganisms Worldwide

open access: yesAdvanced Science, EarlyView.
This study reveals the distinctive pattern and mechanism of rainfall driving the global biodiversity and biogeography of soil potential N‐fixing microorganisms, and constructs the theoretical framework. The results guide us on how to maintain ecosystem productivity under future climate changes (e.g., whether a specific region needs more N fertilizers ...

Sex and the drought [PDF]

open access: yesCurrent Biology, 2008
SummaryAsexual taxa, such as the bdelloid rotifers, are anticipated to help answer the question of what makes sexual reproduction so prevalent and persistent. But perhaps the secret of some asexuals' success lies in their ecological oddity. Florian Maderspacher takes a look.

A Deep Learning Framework for Long-Term Soil Moisture-Based Drought Assessment Across the Major Basins in China

open access: yesRemote Sensing
Drought is a critical hydrological challenge with ecological and socio-economic impacts, but its long-term variability and drivers remain insufficiently understood. This study proposes a deep learning-based framework to explore drought dynamics and their
