Anther and pollen development in some species of Poaceae (Poales) [PDF]

Brazilian Journal of Biology, 2010
Anther and pollen development were studied in Olyra humilis Nees, Sucrea monophylla Soderstr, (Bambusoideae), Axonopus aureus P. Beauv., Paspalum polyphyllum Nees ex Trin. (Panicoideae), Eragrostis solida Nees, and Chloris elata Desv. (Chloridoideae). The objective of this study was to characterise, embryologically, these species of subfamilies which ...

Reproductive biology of Abolboda pulchella and A. poarchon (Xyridaceae: Poales) [PDF]

Annals of Botany, 2011
Abolboda (Xyridaceae) belongs to the Poales, a predominantly wind-pollinated order whose phylogeny has been widely studied in recent years. The reproductive biology of Abolboda pulchella and A. poarchon was studied to determine the main pollination system of these species, providing the first experimental data on reproduction in the Xyridaceae.A field ...

Positive selection and ancient duplications in the evolution of class B floral homeotic genes of orchids and grasses

BMC Evolutionary Biology, 2009
Background Positive selection is recognized as the prevalence of nonsynonymous over synonymous substitutions in a gene. Models of the functional evolution of duplicated genes consider neofunctionalization as key to the retention of paralogues.

Soil Silicon Application Alleviates Drought Stress in Sugar Beet (Beta vulgaris L.)

Journal of Plant Nutrition and Soil Science, EarlyView.
ABSTRACT Background: The increasing frequency and intensity of drought events have led to yield and quality losses in sugar beet production in temperate regions in Central Europe. Under arid conditions, silicon (Si) application reduced beet yield losses under drought. Similar data for temperate climates are missing.

Gene turnover in the common ancestor of all C4 grasses

PLANTS, PEOPLE, PLANET, EarlyView.
Understanding how plants evolve more efficient photosynthesis is important in a warming world where improving crop productivity and resilience is a global priority. By generating the first reference genomes for an early‐diverging group of grasses called the Aristidoideae, we were able to reconstruct the genetic makeup of the last common ancestor of all

Genome size variation and whole-genome duplications in the monocot order Poales [PDF]

Nuclear genome sizes of 54 representative species from 44 genera of the monocot order Poales were investigated by flow cytometry. Small holoploid genomes with

Gut Microbiota of Gray Snub‐Nosed Monkeys: Adaptation to Seasonal Variations Through Energy Compensation and Thermogenesis

Integrative Zoology, EarlyView.
Based on metagenome‐assembled genomes (MAGs), the gut microbiota of the gray snub‐nosed monkeys recovered 1229 non‐redundant MAGs. The gut microbiota showed an enhanced capacity to produce energy substrates with increased conversion activity of these substrates during winter.

Distinctive gene expression in the reduced first thoracic legs of a nymphalid butterfly

Insect Molecular Biology, Volume 35, Issue 5, Page 504-516, October 2026.
Transcriptome analysis reveals that the small non‐walking front legs of a butterfly have distinct gene expression to the four walking legs. Reduced front legs express a gene with putative mechanosensory roles, a blue‐sensitive opsin and two homeobox genes.

A trait‐based integration of competition and abiotic tolerance underlies plant success

New Phytologist, Volume 252, Issue 1, Page 87-99, October 2026.
Competitive effect and abiotic tolerance show positive associations with species' niche breadth and local dominance. Summary Understanding what determines species' ecological success is a central challenge in ecology. Competitive ability and abiotic tolerance are expected to be strong predictors of species success, yet theory predicts a trade‐off ...
