Unifying Retaria Research: A Common Framework for Studying Foraminifera and Radiolaria

open access: yesBioEssays, Volume 48, Issue 6, June 2026.
Research on Foraminifera and Radiolaria has predominantly focused on their fossil remains. This synthesis identifies the “Big Five” disciplines of a unified Retaria research: diversity and evolution, ecology, life cycles, and ecosystem roles, highlighting this lineage as a model system for understanding life's resilience in a rapidly changing planet ...

Development of Maize Haploid Inducer Lines and Doubled Haploid Lines in Pakistan

open access: yes, 2015
The work on maize doubled haploid development has started at the Maize Research Station, Ayub Agricultural Research Institute, Faisalabad, Pakistan during 2010 in collaboration with University of Agriculture Faisalabad, Pakistan. The aim of current study

Zebrafish as an Anti‐Isogenic Vertebrate Model and What It Reveals About Genetic Background and Reproducibility

open access: yesBioEssays, Volume 48, Issue 6, June 2026.
Zebrafish illustrates how polygenic sex determination, maternal germline bottlenecks, and a structurally restless genome jointly destabilize deep homozygosity. These interlocking constraints make fully isogenic zebrafish lines effectively unattainable, turning this model into a natural “stress test” for assumptions about genetic background and ...

Early evolutionary history of the seed

open access: yesBiological Reviews, Volume 101, Issue 3, Page 1511-1553, June 2026.
ABSTRACT The seed is an essential stage in the life history of gymnospermous and angiospermous plants, facilitating both their survival and dispersal. We reappraise knowledge of the evolutionary history of the gymnospermous seed, from its origin in the late Devonian through to the well‐known end‐Permian extinctions – an interval encompassing the ...

Management of the ig gene for haploid induction in maize

open access: yes, 1992
The effect of the ig gene showed the same intensity at the haploid as at the diploid level. This was contrary to the results on the exceptional rate obtained elsewhere, and suggested that haploid manipulation should not be used as a routine procedure. At

Nuclear Entanglement: New Insights Into the Role of Cytoskeleton and Nucleoskeleton in Plant Nuclear Function

open access: yesCytoskeleton, Volume 83, Issue 6, Page 354-375, June 2026.
ABSTRACT Of the three types of cytoskeleton known in animals—actin, microtubules, and intermediate filaments—only actin and microtubules exist in plants. Both play important roles in cellular shaping, organelle movement, organization of the endomembrane system, and cell signaling.

In Vitro Live Cell Imaging Reveals Nuclear Dynamics and Role of the Cytoskeleton During Asymmetric Division of Pollen Mitosis I in Nicotiana Benthamiana

open access: yesCytoskeleton, Volume 83, Issue 6, Page 394-406, June 2026.
ABSTRACT Pollen is a male gametophyte of angiosperms. Following meiosis, the microspore undergoes an asymmetric division called pollen mitosis I (PMI), which produces two cells of different sizes: a large vegetative cell and a small generative cell. Polarized nuclear migration and positioning during PMI are important for successful pollen development ...

Microbial Pressure and Social Immunity: Bumble Bees Increase Brood Hygiene After Exposure to a Bacillus thuringiensis‐Based Biopesticide

open access: yesEcology and Evolution, Volume 16, Issue 6, June 2026.
In social insect colonies, diseased or dead brood is identified and removed by workers to prevent the infection of the whole colony. Here, bumble bee larvae exposed to a bacterium (Bacillus thuringiensis ssp. aizawai (strain: ABTS‐1857)) based biopesticide were removed more frequently than wounded or untreated control larvae. This shows that bumble bee

Optimization of Cultivation System and Transcriptome Analysis: From Unpollinated Chinese Chive Ovules to Plant Formation

open access: yesAgronomy
Unpollinated ovary culture is an effective approach for generating haploid and doubled haploid lines, but its application in Chinese chive (Allium tuberosum) breeding has been constrained by strong genotype dependence and low regeneration efficiency ...

Glacial refugia, postglacial dynamics, and hybrid zones of Pinaceae in Eurasia captured from sedimentary ancient DNA

open access: yesEcosphere, Volume 17, Issue 6, June 2026.
Abstract Boreal forests cover nearly one‐third of global forest area. Glacial cycles have shaped the distribution and connectivity of modern Pinaceae genera, yet species‐level refugia, postglacial migrations, and hybridization patterns remain unclear due to limited high‐resolution taxonomic and temporal data. We applied a hybridization capture approach
