Pollen Histochemistry and Pollen : Ovule Ratios in Zingiberaceae
, 2020 Background and Aims Pollen grains of 37 species from 11 genera in the family Zingiberaceae were examined to assess qualitatively starch or lipid contents; the pollen grain and ovule numbers per flower and pollen : ovule ratios were also counted and ...

New Phytologist, Volume 252, Issue 1, Page 260-275, October 2026.Maize regeneration via somatic embryogenesis by ectopic expression of morphogenic factors TaGRF4‐TaGIF1 and ZmBBM. Summary Transformation is an indispensable tool for plant genetics and functional genomics. Although stable transformation in maize is no longer a major obstacle, there remains a need for accessible and efficient methods for academic ...

Natural Variation in GmSL20 Improves Seed Size and Quality in Soybean
Plant Biotechnology Journal, Volume 24, Issue 10, Page 5300-5316, October 2026.ABSTRACT Seed size plays an important role in determining crop yield, yet the genetic mechanisms underlying the regulation of this agronomic trait remain incompletely understood in soybean. Here, we perform a genome‐wide association study mapping with seed length variations and identify a major quantitative trait locus (QTL) on chromosome 20, named ...

The Spatiotemporal Genetic Architecture of Seed Vigor in Upland Cotton
Advanced Science, Volume 13, Issue 50, 7 September 2026.Leveraging the semi‐automated SeedRanger platform, we profiled the germination kinetics of 356 cotton accessions at a 30‐min interval. This high‐throughput phenomic approach delineated a temporal genetic network comprising 541 stage‐specific loci. Crucially, functional validation identified FLA2 as a pivotal, auxin‐modulated regulator that orchestrates

Agrosystems, Geosciences &Environment, Volume 9, Issue 3, September 2026.Abstract The environmental drawbacks of chemical phosphate fertilizers have heightened interest in biofertilizers as sustainable alternatives. However, their efficacy is frequently genotype‐dependent, a factor often neglected in broad recommendations. This study investigated the interaction between the phosphate‐solubilizing biofertilizer Barvar 2 and ...

American Journal of Botany, Volume 113, Issue 9, September 2026.Abstract Premise The modern distribution of the southern cypresses, Callitroideae (Cupressaceae), reflects a classic Gondwanan distribution. The initial diversification of Callitroideae is estimated to have occurred during the Cretaceous, yet fossils from this period are rare, hampering our understanding of its early evolutionary history.

American Journal of Botany, Volume 113, Issue 9, September 2026.Abstract Premise Although Pararaucaria seed cones were first described 90 years ago, only in the last dozen years have we discovered the greater extent of the species diversity and paleogeographic range of the genus. Pararaucaria is now known across the mid‐latitudes of the Lower Jurassic to Lower Cretaceous in the northern and southern hemispheres ...

Feddes Repertorium, Volume 137, Issue 3, September 2026.ABSTRACT Corsia (Corsiaceae) is a remarkable genus of achlorophyllous, fully mycoheterotrophic plants distributed across New Guinea, the Solomon Islands, and Northern Australia. The genus has often been considered an example of adaptive radiation amongst mycoheterotrophic plants, with 25 narrowly endemic species, most known from just one or two ...

Pollen-Ovule Ratio and Gamete Investment in Pedicularis (Orobanchaceae)
, 2007 The Pedicularis species provides ideal materials to study floral evolution because of their substantial flower variation based on a narrow genetic basis, even though they are almost exclusively pollinated by bumblebee. These traits allow us to detect the
