Carbonic anhydrase network of genes trigger cytosolic pH enabling differentiation from quiescence

BackgroundCarbonic anhydrase regulates various cellular processes. Intracellular pH flux impacted by carbonic anhydrase alters the enzymes allosteric active site which effects several downstream cellular processes. Earlier, we reported that, the catalytic activity of carbonic anhydrase is independent, but direction of catalysis is affected by cellular pH level. On the other hand carbonic anhydrase alters the cytosolic pH level to facilitate allosteric phosphorylation of proteins which further leads to cellular differentiation through a process being regulated by ncRNAs.\n\nResultsThis study illustrates various ways of cell differentiation/ organ development regulation via carbonic anhydrase interacting network of proteins involved in various cellular processes. It is involved in protein degradation process of other proteins like RPT, 26S proteasome, AT3G15120 and its variant producing ncRNA, etc. Carbonic anhydrase indirectly involved in signaling process along with MAPK in providing innate resistance against biotic and abiotic stresses. It is also indirectly linked to cell membrane transporters like H+-ATPase and V-ATPase B.\n\nConclusionsThough carbonic anhydrase is not directly linked with EMS1 as revealed by network analyses and protein-protein interaction there could be a suitable condition generated by the carbonic anhydrase for EMS1 to be active. Hence, we report that carbonic anhydrase, along with other pH regulating gene complexes plays a major role for making EMS1 functional.

Fast, versatile, and quantitative annotation of complex images

We report a generic smartphone app for quantitative annotation of complex images. The app is simple enough to be used by children, and annotation tasks are distributed across app users, contributing to efficient annotation. We demonstrate its flexibility and speed by annotating >30,000 images, including features of rice root growth and structure, stem cell aggregate morphology, and complex worm (C. elegans) postures, for which we show that the speed of annotation is >130-fold faster than state-of-the-art techniques with similar accuracy.

FabElm_BarcodeDb: matK barcode database of legumes

BackgroundDNA barcoding is an imperative implementation of chloroplast rbcL and matK regions exploited as standard molecular barcodes for species identification. MatK is highly conserved in plants and has been used extensively as a phylogenetic marker for classification of plants. In this study matK sequences of Leguminosae were retrieved for variant analysis and phylogentics. From online resources, maturase sequences were retrieved; redundant sequences and partials along with poor quality reads were filtered to compile 3639 complete non-redundant matK sequences and constructed into a database for ready reference. The database FabElm_BarcodeDb made available at app.bioelm.com was constructed using available sequence resources.\n\nResultsThe chloroplast genome of plants contains matK gene of 1500 bp, positioned between intron of trnK associated in-group II intron splicing. Mitochondrial matR and genomic matN sequences were compared with chloroplast matK. These maturase sequences share regions of homology with chloroplast and mitochondrial regions and are expected to be regulated by miRNA in producing splice variants contributing to speciation.\n\nConclusionBase substitution rates of nuclear maturase were comparable with mitochondrial maturase and are different from matK sequences. Hence, few identified species in this investigation were clustered with other tribes when analysed using matK. MatK is effective in resolving the species level variations as splicing contributes to speciation; but utilization of matK alone as a barcode marker for legumes is dubious, as it could not resolve some species identity.\n\nAbbreviations
