An inverse latitudinal gradient in intraspecific genetic diversity of a dominant ant in the neotropical savanna

Ecosphere, Volume 17, Issue 4, April 2026.
Abstract Although latitudinal gradient of diversity (LGD) is a biogeographic pattern widely shown for distinct animal groups, some display the opposite pattern, with biodiversity peaking away from the equator. These inverse gradients may result from drivers that also overlap with extrinsic factors shaping genetic diversity across taxa, a level of ...

Modulating Drought Stress Response of Maize by a Synthetic Bacterial Community

Frontiers in Microbiology, 2021
Plant perception and responses to environmental stresses are known to encompass a complex set of mechanisms in which the microbiome is involved. Knowledge about plant physiological responses is therefore critical for understanding the contribution of the

The Blue List Initiative: Guiding Biodiversity Restoration in Brazil's Espinhaço Range

Applied Vegetation Science, Volume 29, Issue 2, April/June 2026.
The campo rupestre is a biodiversity hotspot marked by extreme habitat heterogeneity and high species turnover. Using phytosociological data, floristic clustering and zeta diversity, we show that habitats are floristically non‐interchangeable and propose habitat‐ and substrate‐specific Blue Lists to guide effective, locality‐based ecological ...

Drought tolerance classification using unmanned aerial systems based on RGB and multispectral data

Frontiers in Plant Science
Drought poses a global threat to food security and demands intensified efforts from breeding programs. Yet the lack of efficient methods for selecting this trait increases the cost and time required to develop new cultivars.

Temporal field phenomics of transgenic maize events subjected to drought stress: Cross‐validation scenarios and machine learning models

The Plant Phenome Journal, Volume 8, Issue 1, December 2025.
Abstract Global climate change has driven breeding programs to develop abiotic stress‐resilient plant varieties. Traditionally, assessing drought resilience involves labor‐intensive and time‐consuming processes. This study used an unmanned aerial system (UAS) to predict key phenotyping traits in maize (Zea mays L.) and monitor plant response to drought

Reactive oxygen species act as signaling molecules to control root hair initiation and tip growth

New Phytologist, Volume 247, Issue 5, Page 2042-2048, September 2025.
Summary Root hairs (RHs) increase the surface area of roots, facilitating nutrient and water uptake and plant anchorage. RHs form from root epidermal cells and elongate by polar tip growth. Reactive oxygen species (ROS) have recently been implicated as important signals that drive RH formation and elongation using both genetic and imaging approaches ...

Beyond the Local Catchment: Influence of Regional Context and Land Use Legacy on Current Stream Fish Diversity in Agricultural Systems

Aquatic Conservation: Marine and Freshwater Ecosystems, Volume 35, Issue 8, August 2025.
ABSTRACT Land use poses a major threat to global biodiversity, impacting ecosystems across various spatial and temporal scales. Recent studies suggest that past land use changes influence the observed contemporary diversity patterns in stream fish assemblages more strongly than current land use.

Structural Characterization of Maize SIRK1 Kinase Domain Reveals an Unusual Architecture of the Activation Segment

Frontiers in Plant Science, 2017
Kinases are primary regulators of plant metabolism and excellent targets for plant breeding. However, most kinases, including the abundant receptor-like kinases (RLK), have no assigned role.
