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

Sickle cell retinopathy molecular investigation through proteomic analysis of Townes HbSS mice retinas

Experimental Biology and Medicine
Sickle cell retinopathy (SCR) is the most important ocular manifestation in sickle cell disease (SCD). Retinal tissue is highly sensible to vaso-occlusion and hypoxia observed in SCR pathophysiology, with consequent vessel remodeling and ultimately ...

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.
