OsRAD17 Is Required for Meiotic Double-Strand Break Repair and Plays a Redundant Role With OsZIP4 in Synaptonemal Complex Assembly

open access: yesFrontiers in Plant Science, 2018
The repair of SPO11-dependent double-strand breaks (DSBs) by homologous recombination (HR) ensures the correct segregation of homologous chromosomes. In yeast and human, RAD17 is involved in DNA damage checkpoint control and DSB repair.

Molecular Insights into Fungal Glycosylphosphatidylinositol Transamidase Complex

open access: yesAdvanced Science, EarlyView.
The glycosylphosphatidylinositol (GPI) biosynthesis pathway is critical for antifungal drug development. This study reports three cryo‐electron microscopy structures of fungal GPI transamidase (GPIT), captured in two substrate‐bound states and a novel dimeric assembly.

Allelic Variation in Maize Malate Dehydrogenase 7 Shapes Promoter Methylation and Banded Leaf and Sheath Blight Resistance

open access: yesAdvanced Science, EarlyView.
In this study maize chloroplastic malate dehydrogenase7 (ZmMDH7), is identified as a Rhizoctonia solani resistance gene in maize. ZmMDH7 is regulated by transcription factor ZmWRKY44 via pathogens challenge to elevate mitochondrial ROS and SA signaling pathway.

Nuclear reorganization and homologous chromosome pairing during meiotic prophase require C. elegans chk-2.

open access: yesGenes & Development, 2001
Analysis of mutants defective in meiotic chromosome pairing has uncovered a role for Caenorhabditis elegans chk-2 in initial establishment of pairing between homologous chromosomes during early meiotic prophase.

Model‐Guided Systematic Metabolic Engineering for Enhanced Spinosad Biosynthesis in Saccharopolyspora spinosa NHF132

open access: yesAdvanced Science, EarlyView.
A genome‐scale model guided the systematic metabolic engineering of Saccharopolyspora spinosa, enabling a 5.5‐fold boost in the green bioinsecticide spinosad to 1.8 g L−1 and establishing an actinomycete framework for complex natural products overproduction.

Somatic Pairing in Drosophila virilis Mitosis [PDF]

open access: yes, 1975
In neuroblast cells homologous chromosomes tend to pair during prophase of mitosis. Heterochromatic elements of homologous chromosomes are widely separated in very early prophase, at which time the euchromatin is poorly stained.
