Growth, Photosynthesis and Root Metabolome Responses to Graded Hypoxia in Contrasting Rice Cultivars

Journal of Agronomy and Crop Science, Volume 212, Issue 3, May 2026.
ABSTRACT Rice is an economically important crop and a staple food for a large proportion of the world's population. Although rice is generally adapted to flooded soils, cultivars may differ in their responses to reduced oxygen availability. Here, we evaluated growth, physiological performance and organ‐specific metabolic profiles of two rice cultivars ...

Identification of Phloem Involved in Assimilate Loading in Leaves by the Activity of the Galactinol Synthase Promoter [PDF]

Plant Physiology, 2000
Abstract The definition of “minor” veins in leaves is arbitrary and of uncertain biological significance. Generally, the term refers to the smallest vein classes in the leaf, believed to function in phloem loading. We found that a galactinol synthase promoter, cloned from melon (Cucumis melo), directs expression of thegusA gene to the ...

Capturing Early‐Stage Chilling Response in Field‐Grown Sorghum and Maize by Integrating Aerial Phenotyping and Metabolomic Signatures

Physiologia Plantarum, Volume 178, Issue 3, May/June 2026.
ABSTRACT Early‐season chilling limits sorghum establishment in temperate environments, yet the metabolic basis of this sensitivity remains poorly understood. We combined temporal spectral reflectance with untargeted metabolomics to characterize species and genotype‐level responses to early planting conditions.

Soybean seed galactinol synthase activity as determined by a novel colorimetric assay [PDF]

Revista Brasileira de Fisiologia Vegetal, 2000
Galactinol synthase (GS) is a key enzyme for the biosynthesis of raffinose oligosaccharides (RO) which are the flatulence factors present in soybean seeds and several other legumes. Understanding of soybean seed GS properties is, therefore, of biotechnological interest.

Investigating the Chemical, Antifungal, and Cytotoxic Properties of Cochlospermum vitifolium Leaves and Stem Bark Extracts

Chemistry &Biodiversity, Volume 23, Issue 4, April 2026.
This figure contains images created by Freepik from Flaticon. ABSTRACT Comprehensive analysis of the chemical properties and bioactivities of plant extracts is essential for identifying compounds with therapeutic potential. This study analyzed hydroethanolic extracts from the leaves and stem bark of Cochlospermum vitifolium, investigating their ...

Decoding plant defense signaling using the defenseless mutant

New Phytologist, Volume 250, Issue 2, Page 1141-1156, April 2026.
Summary Can plants live without defenses? Mutant analysis in Arabidopsis thaliana has identified numerous regulators of biotic, abiotic, and hormone‐based defenses, but the redundancy among separate defense pathways remains unexplored. We constructed an Arabidopsis mutant, defenseless, lacking six canonical defense pathways using abi1‐1 (abscisic acid),

Environmental stress reveals new insights regarding proteome rebalancing in Arabidopsis thaliana seeds

The Plant Journal, Volume 126, Issue 2, April 2026.
SUMMARY Seeds are resilient to genetic and envirxonmental perturbation. For example, they can compensate for the loss of highly abundant seed storage proteins (SSPs) while maintaining amino acid levels and composition, a process known as proteome rebalancing.

Divergent Transcriptional Architectures Beyond Core CAM Genes in Facultative and Constitutive CAM Species in Tillandsia L.

Molecular Ecology, Volume 35, Issue 6, March 2026.
ABSTRACT Crassulacean acid metabolism (CAM) is a water‐efficient photosynthetic strategy involving a coordinated suite of complex traits including metabolic, anatomical and regulatory aspects that shift across the diel cycle. While CAM has evolved repeatedly in land plants, the evolutionary routes enabling this convergence remain elusive.

Soluble carbohydrate content variation in Sanionia uncinata and Polytrichastrum alpinum, two Antarctic mosses with contrasting desiccation capacities

Biological Research
BACKGROUND: Cryptogamic vegetation dominates the ice-free areas along the Antarctic Peninsula. The two mosses Sanionia uncinata and Polytrichastrum alpinum inhabit soils with contrasting water availability. Sanionia uncinata grows in soil with continuous
