    Chromatin and gene expression changes during female Drosophila germline stem cell development illuminate the biology of highly potent stem cells

    Liang-Yu Pang, Steven DeLuca ... Allan C Spradling
    Chromatin changes downstream from Drosophila germline stem cells and fertilized zygotes alter how transposable element activity and gene expression are controlled to facilitate differentiation.

    SET-9 and SET-26 are H3K4me3 readers and play critical roles in germline development and longevity

    Wenke Wang, Amaresh Chaturbedi ... Siu Sylvia Lee
    Two SET-domain containing proteins regulate H3K4me3 by their binding to H3K4me3 through their PHD domain and directly regulate expression of a subset of genes.

    Conservation of oocyte development in germline cysts from Drosophila to mouse

    Allan C Spradling, Wanbao Niu ... Bhawana Maurya
    Early oocyte development takes place in germline cysts and is strikingly conserved from Drosophila to mouse, reflecting common mechanisms that may help reverse aging and specify oocyte and early embryo polarity.

    The need for high-quality oocyte mitochondria at extreme ploidy dictates mammalian germline development

    Marco Colnaghi, Andrew Pomiankowski, Nick Lane
    Selective transfer of mitochondria in the Balbiani body ensures high-quality oocyte mitochondria at extreme ploidy, explaining many enigmatic features of female germline architecture including germ cell loss.

    Maternal H3K36 and H3K27 HMTs protect germline development via regulation of the transcription factor LIN-15B

    Chad Steven Cockrum, Susan Strome
    The H3K36 and H3K27 histone methyltransferases MES-4 and PRC2 protect survival of the nascent germline in Caenorhabditis elegans by repressing expression of X-linked genes, including the key transcription factor LIN-15B.

    OVO positively regulates essential maternal pathways by binding near the transcriptional start sites in the Drosophila female germline

    Leif Benner, Savannah Muron ... Brian Oliver
    Many well-studied maternal developmental pathways that are required for embryonic development in Drosophila are regulated by the transcription factor OVO in the Drosophila female germline.

    Stem cell heterogeneity drives the parasitic life cycle of Schistosoma mansoni

    Bo Wang, Jayhun Lee ... Phillip A Newmark
    Distinct stem cell populations drive larval, somatic, and germline development of the human parasitic flatworm, Schistosoma mansoni.

    Compartmentalized oskar degradation in the germ plasm safeguards germline development

    Catherine E Eichler, Anna C Hakes ... Elizabeth R Gavis
    RNP granules confer temporal and spatial regulation of oskar mRNA degradation to minimize inheritance of oskar mRNAby germ cells and thereby protect germline development.

    An actin-related protein that is most highly expressed in Drosophila testes is critical for embryonic development

    Courtney M Schroeder, Sarah A Tomlin ... Harmit S Malik
    Non-canonical ‘testis-specific’ actin-related protein (Arp), Arp53D, is critical for early embryonic development in Drosophila, revealing important roles for lineage-specific, divergent, testis-expressed non-canonical Arps outside the male germline in animals.

    SNPC-1.3 is a sex-specific transcription factor that drives male piRNA expression in C. elegans

    Charlotte P Choi, Rebecca J Tay ... John K Kim
    snpc-1.3 specifies male piRNA transcription and is regulated by the sex determination pathway.
