Gene turnover in the common ancestor of all C4 grasses

open access: yesPLANTS, PEOPLE, PLANET, Volume 8, Issue 6, Page 2217-2234, November 2026.
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

Unprecedented variation pattern of plastid genomes and the potential role in adaptive evolution in Poales

open access: yesBMC Biology
Background The plastid is the photosynthetic organelle in plant cell, and the plastid genomes (plastomes) are generally conserved in evolution. As one of the most economically and ecologically important order of angiosperms, Poales was previously ...

Single‐cell Transcriptome Profiling Reveals Gene Regulatory Networks and Key Genes in the Root Epidermis and Cortical Cells Associated with Early Nodulation in Glycine Max

open access: yesAdvanced Science, Volume 13, Issue 55, 5 October 2026.
Single‐cell transcriptomics of soybean roots soon after rhizobial inoculation reveals epidermal and cortical cell‐specific programs and gene‐regulatory networks acting in symbiosis establishment. We identify an ethylene‐driven regulatory circuit involving WRKY6.3/6.4 transcription factors targeting select Nod19 genes that promotes infection‐thread ...

Placing very long branch taxa in the plant tree of life: A case study with Dioscoreales mycoheterotrophs

open access: yesAmerican Journal of Botany, Volume 113, Issue 10, October 2026.
Abstract Premise The inclusion of heterotrophic plants in broader systematic studies is challenging due to substantial morphological modification, gene loss, and accelerated substitution rates following photosynthesis loss. In particular, inclusion of very long branch (VLB) taxa with highly elevated rates may lead to phylogenomic misinference.

Climate warming may erode thermal barriers to pest invasion in tropical alpine ecosystems: Evidence from the Andes

open access: yesEcosphere, Volume 17, Issue 10, October 2026.
Abstract Climate warming is increasingly enabling species to cross bioclimatic barriers, driving altitudinal range expansions of species and facilitating biological invasions into ecosystems that were historically protected by low temperatures. Among these cold ecosystems are tropical alpine systems—páramos—found in the tropical Andes above 3000 m ...

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

open access: yesJournal of Plant Nutrition and Soil Science, Volume 189, Issue 5, Page 746-762, October 2026.
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.

Treasures of the Serra da Jiboia (Bahia, Brazil): a new species of Racinaea and an overview of the local Bromeliaceae flora

open access: yesNordic Journal of Botany, Volume 2026, Issue 10, October 2026.
Serra da Jiboia, located in the south‐central region of Bahia, represents an important ecotone between the Atlantic Forest and the Caatinga and harbors high floristic diversity and numerous endemic species. The Bromeliaceae family, well represented in the region, stands out for its ecological importance and adaptability to various microenvironments ...

The Effect of Grain Type on Virulence of Entomopathogenic Fungi Against Stored Product Pests

open access: yesApplied Sciences, 2020
Fungal virulence is multifaceted and dependent on multiple abiotic factors. The present study represents an investigation of the effect of one such abiotic factor, that of the grain type, on the insecticidal action of three entomopathogenic fungal ...
