Haploid Induction via In vitro Gynogenesis in Tomato (Solanum lycopersicum L.)

Journal of Integrative Agriculture, 2014
In order to determine the potential for haploid induction via in vitro gynogenesis in tomato, the ovules and protoplasts of embryo sacs from the hybrids Zhongza 101 and Zhongza 105 were cultured.

Under-dominance constrains the evolution of negative autoregulation in diploids [PDF]

, 2013
Regulatory networks have evolved to allow gene expression to rapidly track changes in the environment as well as to buffer perturbations and maintain cellular homeostasis in the absence of change.

The mitochondrial DNA copy number and ovary‐related reproductive disorders: A bidirectional two‐sample Mendelian randomization study

International Journal of Gynecology &Obstetrics, Volume 169, Issue 1, Page 112-120, April 2025.
Abstract Objective In the present study, a bidirectional two‐sample Mendelian randomization approach was utilized to explore potential causal relationships between mitochondrial DNA copy number (mtDNA‐CN) and ovary‐related reproductive disorders (ORRDs), including ovarian dysfunction, ovarian cyst, polycystic ovary syndrome (PCOS), premature ovarian ...

fCUT&Tag‐Seq: An optimized CUT&Tag‐based method for high‐resolution profiling of histone modifications and chromatin‐binding proteins in fungi

mLife, EarlyView.
Abstract Histone modifications and chromatin‐binding proteins play crucial roles in regulating gene expression in eukaryotes, with significant implications for fungal pathogenicity and development. However, profiling these modifications or proteins across the genome in fungi remains challenging due to the technical limitations of the traditional ...

Clinicopathological significance of loss of Y chromosome in male meningiomas

The Journal of Pathology, EarlyView.
Abstract Male meningiomas, comprising approximately 30% of all meningiomas, are more frequently high‐grade and associated with poorer clinical outcomes compared to their female counterparts. Although Y chromosome alterations have been studied in various male‐predominant tumors, a limited number of studies have evaluated their role in meningiomas.

Influence of different wheat and Imperata cylindrica genetic backgrounds on haploid induction efficiency in wheat doubled haploid breeding

Czech Journal of Genetics and Plant Breeding, 2014
Four Indian and one Japanese accession of Imperata cylindrica were assessed for their influence upon haploid production in F1 generations of 21 wheat crosses (winter × spring, spring × spring and winter × winter) to find an efficient pollen source for ...

Deep Proteomic Profiles of the Antarctic Diatom Fragilariopsis Cylindrus Under Varying Iron and Manganese Conditions

PROTEOMICS, EarlyView.
ABSTRACT Fragilariopsis cylindrus is a key diatom in the Southern Ocean, where low iron and manganese availability constrain primary production and biogeochemical activity. The molecular mechanisms used by polar diatoms, including F. cylindrus, to cope with trace metal limitations remain largely unexplored.
