DNA Replication Errors Drive Genome‐Wide Small Inverted Triplication Dynamics

open access: yesAdvanced Science, EarlyView.
This study provides insight into the dynamic equilibrium mechanism of a novel structural variant, small inverted triplication (SIT), which is generated by misalignment of the 3’ flap generated under DNA replication stress with palindromic sequence. Alternatively, the end sequence may fold back on itself to form an inverted fragment.

Induction of parthenogenetic haploid plants with brassinolide

open access: yesGenes & Genetic Systems, 1994
A plant steroid hormone, brassinolide, was found to induce parthenogenetic haploid seed generation when applied to the stigmas of the castrated flower buds. In the two species examined, Arabidopsis thaliana and Brassica juncea, haploid seeds were obtained which developed to stable haploid plants, but in the third species, Tradescantia paludosa, haploid

Two Routes to Land: Genomic Underpinnings of Parallel Aerial Egg Deposition in Aquatic Old‐World Pila and New‐World Pomacea (Ampullariidae)

open access: yesAdvanced Science, EarlyView.
Comparative genomics of Gondwana‐diverged Pila and Pomacea reveals parallel evolution of aerial oviposition. Convergent chromosomal rearrangements reshape regulatory landscapes within topologically associating domains. Lineage‐specific gene family expansions and viral‐derived perivitelline proteins (PV1) underpin desiccation resistance.

Single nucleus sequencing reveals spermatid chromosome fragmentation as a possible cause of maize haploid induction

open access: yesNature Communications, 2017
Plant breeders can produce haploid maize lines using haploid inducer lines as pollen donors. Here, by sequencing the genomes of single pollen nuclei, Li et al.

Metabolic Imbalance Triggers Adaptive Remodeling to Accelerate Diploidization in Murine Haploid Embryonic Stem Cells

open access: yesAdvanced Science, EarlyView.
In this article, Shuai and colleagues demonstrate that metabolic remodeling drives self‐diploidization in murine haploid ESCs (haESCs). Mitochondrial dysfunction and imbalanced pyruvate metabolism underlie this process. Genome‐wide screening using haESCs identifies key mitochondrial quality‐control related genes, enabling a metabolism‐based medium that

Efficiency of three haplomethods in durum wheat (Triticum turgidum subsp. durum Desf.): isolated microspore culture, gynogenesis and wheat × maize crosses

open access: yesCzech Journal of Genetics and Plant Breeding, 2019
This study presents the first report comparing the efficiency of microspore culture, gynogenesis and durum wheat × maize crosses for haploid plant production from three durum wheat genotypes (Razzek, Karim and Jneh Khotifa).

Achieving High‐Density and Stress‐Resilient Maize Breeding Via Germplasm Innovation

open access: yesAdvanced Science, EarlyView.
Global population growth and climate change have exacerbated the global food crisis. This perspective presents a conceptual framework focusing on enhancing population advantages. Several novel breeding objectives are proposed to improve density tolerance and stress resistance for yield improvement.

Microbial Odorant Detection Guides Drosophila Parasitoids Seeking Hosts in Fermenting Fruits

open access: yesAdvanced Science, EarlyView.
Yeast microbes in fermenting fruits attract both host flies and their parasitoid wasps. Female Leptopilina boulardi detect yeast‐emitted ethyl esters via two olfactory receptors, LbouOR167 and LbouOR136. A conserved residue, Leu159, is critical for binding these compounds, enabling female wasps to locate host‐rich habitats.

MIS12 Is Required for Kinetochore‐Microtubule Attachment in Oocyte Meiosis

open access: yesAdvanced Science, EarlyView.
A model depicting the role of MIS12 in K‐MT attachment during oocyte meiosis. The presence of MIS12 stabilizes bipolar K‐MT attachments by maintaining the function of NDC80 and its interaction with TUBB. This, in turn, promotes KNL1 assembly and subsequent SAC protein recruitment to kinetochores.
