Pollen Viability, Germination and Tube Elongation Responses to Heat Stress During the Reproductive Stage in Maize

Journal of Agronomy and Crop Science, Volume 212, Issue 5, September 2026.
ABSTRACT Climate change‐induced heat stress increasingly threatens crop production, particularly when high temperatures occur during the sensitive flowering stage. In maize, successful fertilization depends on viable pollen, successful pollen germination and subsequent pollen tube elongation reaching the ovule.

Physiological and Morphological Responses of Soybean to Water Stress and Rehydration: Implications for Growth, Seed Yield and Quality

Journal of Agronomy and Crop Science, Volume 212, Issue 5, September 2026.
ABSTRACT Rapid stomatal regulation is an early response associated with improved maintenance of leaf water status and post‐stress recovery in soybean, but it cannot fully offset the detrimental effects of severe drought on seed production. This study evaluated the physiological and morphological responses of soybean genotypes to progressive water ...

The IKU2/RLK7–MAPK–MINI3 signaling module controls endosperm cellularization timing to determine seed size in Arabidopsis

Journal of Integrative Plant Biology, Volume 68, Issue 9, Page 3374-3390, September 2026.
The phosphorylation status of the WRKY transcription factor WRKY10/MINI3, controls the timing of endosperm cellularization in Arabidopsis, thus regulating final seed size, offering a molecular understanding that could inform future agricultural breeding strategies. ABSTRACT Seed size is a critical factor in determining crop yield.

Local Trade‐Offs Shape Flower Size Evolution Across Arabidopsis thaliana Distribution

Molecular Ecology, Volume 35, Issue 17, September 2026.
ABSTRACT The remarkable variation in floral form and size is thought to have driven the evolutionary radiation of angiosperms and has traditionally been attributed to pollinator‐mediated selection on floral displays, yet emerging evidence indicates that abiotic environmental factors can also generate and filter variation in flower size.

The richness, frequency and relatedness components of mate diversity and mate portfolios

New Phytologist, Volume 251, Issue 6, Page 3703-3713, September 2026.
The effects of (a) equal and (b, c) unequal contributions to mate portfolios by 10 mates on (d) Hill‐number mate diversity profiles (see Eqn 1). Summary Sexual reproduction produces genetically diverse families, especially when individuals mate with multiple partners.
