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…

Mashup Score: 0Detection and characterization of genome-wide mutations in M1 vegetative cells of gamma-irradiated Arabidopsis - 2 year(s) ago
Author summary Mutations that occur in plant genome are not only related to plant evolution and speciation in nature, and also useful to identify novel gene functions and to develop new cultivars. Ionizing radiations induce various types of mutations throughout genomes in individual cells of an irradiated/mutagenized plant. However, current knowledge on radiation-induced genome-wide mutations in…

Mashup Score: 18NAD-seq for profiling the NAD+ capped transcriptome of Arabidopsis thaliana: STAR Protocols - 2 year(s) ago
Summary Eukaryotic RNAs can be modified with a non-canonical 5′ nicotinamide adenine dinucleotide (NAD+) cap. NAD-seq identifies transcriptome-wide NAD+ capped RNAs. NAD-seq takes advantage of click chemistry to allow the capture of NAD+ capped RNAs. Unlike other approaches, NAD-seq does not require DNA synthesis on beads, but this technique uses full NAD+ capped…

Author summary High salinity severely affects plant growth and development, impairing crop production worldwide. E3 ligase is a stress-responsive regulator through ubiquitin-proteasome system for selective protein degradation. The E3s are regulated by transcriptional regulation and post-translational modifications. Here, we have discovered that stress-responsive AS acts as a post-transcriptional…

Mashup Score: 0Analysis of cellulose synthase activity in Arabidopsis using spinning disk microscopy: STAR Protocols - 2 year(s) ago
Summary We describe sample preparation and visualization of fluorescently tagged cellulose synthases in cellulose synthase complexes at the plasma membrane of Arabidopsis hypocotyl epidermal cells using live-cell imaging via spinning disk microscopy. We present a technique for sample mounting that may be suitable for imaging other samples. Additionally, we offer free,…

Mashup Score: 4A CENH3 mutation promotes meiotic exit and restores fertility in SMG7-deficient Arabidopsis - 2 year(s) ago
Author summary Meiosis is a reductional cell division that halves number of chromosomes during two successive rounds of chromosome segregation without intervening DNA replication. Such mode of chromosome segregation requires extensive reprogramming of the cell division machinery at the entry to meiosis, and inactivation of the meiotic program upon the formation of haploid spores. Here we showed…
