Mashup Score: 0APOK3, a pollen killer antidote in Arabidopsis thaliana - 11 month(s) ago
Present in many taxa, gamete killers are genetic loci where one allele—the killer—enhances its transmission by destroying gametes that do not carry it. Here, Si

Mashup Score: 0RADA-dependent branch migration has a predominant role in plant mitochondria and its defect leads to mtDNA instability and cell cycle arrest - 2 year(s) ago
Author summary In flowering plants, the mitochondrial genome is very large and dynamic, and its stability influences plant fitness and development. Rearrangements by recombination drive its very rapid evolution and can lead to valuable agronomic traits such as cytoplasmic sterility, used by breeders for the production of hybrid seeds. Here we describe RADA, a DNA helicase essential for the…

Mashup Score: 0The nitrate-inducible NAC transcription factor NAC056 controls nitrate assimilation and promotes lateral root growth in Arabidopsis thaliana - 2 year(s) ago
Author summary Nitrogen is not only a major nutrient element in plants, but also an important signal molecule for plant growth and metabolism. However, the underlying molecular mechanism of nitrate signal transduction, leading to root development response, is still unclear. In this study, by screening the subfamily III NAC transcription factors, we found the potential function of a new NAC family…

Mashup Score: 0PIN3 positively regulates the late initiation of ovule primordia in Arabidopsis thaliana - 2 year(s) ago
Author summary Ovule is the precursor of seed. Ovule initiation determines maximum ovule number and has great impact on seed number and yield. Understanding the process and regulation of ovule initiation has both scientific significance and potential application. Although the process and its related genes have been reported, the underling mechanisms remains elusive. We previously reported the…

Mashup Score: 1Histone demethylase IBM1-mediated meiocyte gene expression ensures meiotic chromosome synapsis and recombination - 2 year(s) ago
Author summary Meiosis is essential for sexual reproduction in most eukaryotes, including plants. In recent years, epigenetic modification such as DNA methylation, histone modifications and histone variants has been shown to play essential roles in meiosis likely by regulating chromatin structure and gene expression. However, the role of histone demethylases in regulating meiotic progression…
