Project description:Restriction site Associated DNA (RAD) tags are a genome-wide representation of every site of a particular restriction enzyme by short DNA tags. Most organisms segregate large numbers of DNA sequence polymorphisms that disrupt restriction sites, which allow RAD tags to serve as genetic markers spread at a high-density throughout the genome. Here, we demonstrate the applicability of RAD markers for both individual and bulk-segregant genotyping. First, we show that these markers can be identified and typed on pre-existing microarray formats. Second, we present a method that uses RAD marker DNA to rapidly produce a low-cost microarray genotyping resource that can be used to efficiently identify and type thousands of RAD markers. We demonstrate the utility of the former approach by using a tiling path array for the fruit fly to map a recombination breakpoint, and the latter approach by creating and utilizing an enriched RAD marker array for the threespine stickleback. The high number of RAD markers enabled localization of a previously identified region, as well as a second novel region also associated with the lateral plate phenotype. Taken together, our results demonstrate that RAD markers, and the method to develop a RAD marker microarray resource, allow high-throughput, high-resolution genotyping in both model and non-model systems.

Project description:MicroRNAs (miRNAs) are endogenous, noncoding, short RNAs directly involved in regulating gene expression at the post-transcriptional level. In spite of immense importance, limited information of P. vulgaris miRNAs and their expression patterns prompted us to identify new miRNAs in P. vulgaris by computational methods. Besides conventional approaches, we have used the simple sequence repeat (SSR) signatures as one of the prediction parameter. Moreover, for all other parameters including normalized Shannon entropy, normalized base pairing index and normalized base-pair distance, instead of taking a fixed cut-off value, we have used 99% probability range derived from the available data. We have identified 208 mature miRNAs in P. vulgaris belonging to 118 families, of which 201 are novel. 97 of the predicted miRNAs in P. vulgaris were validated with the sequencing data obtained from the small RNA sequencing of P. vulgaris. Randomly selected predicted miRNAs were also validated using qRT-PCR. A total of 1305 target sequences were identified for 130 predicted miRNAs. Using 80% sequence identity cut-off, proteins coded by 563 targets were identified. The computational method developed in this study was also validated by predicting 229 miRNAs of A. thaliana and 462 miRNAs of G. max, of which 213 for A. thaliana and 397 for G. max are existing in miRBase 20. There is no universal SSR that is conserved among all precursors of Viridiplantae, but conserved SSR exists within a miRNA family and is used as a signature in our prediction method. Prediction of known miRNAs of A. thaliana and G. max validates the accuracy of our method. Our findings will contribute to the present knowledge of miRNAs and their targets in P. vulgaris. This computational method can be applied to any species of Viridiplantae for the successful prediction of miRNAs and their targets. Small RNA sequencing was done for 10 days old seedlings of Phaseolus vulgaris Cv. Anupam

Project description:One of the most recognizable physiological phenomena is the adrenergic-induced fight-or-flight increase in heart rate and cardiac contraction. For the β-adenergic agonist-induced enhancement of calcium influx and transients, and contractility in the heart, we identify the dual requirement of a subpopulation of Rad-bound calcium channels under basal conditions and PKA phosphorylation of Rad. In mice expressing a non-phosphorylatable Rad mutant, basal cardiac contractility is reduced and adrenergic-augmentation of the calcium current and contractility are disabled. Expression of mutant calcium channel β-subunits that cannot bind the mutant Rad restored contractility, revealing a highly specific therapeutic approach to mimic the contractility imparted by adrenergic agonists. Our findings place Rad and its modulation of calcium channels at the nexus of adrenergic modulation of cardiac responses.

Project description:We report an small RNA sequencing (sRNA-seq) approach to identify host sRNAs involved in the nitrogen fixing symbiosis between Mesoamerican Phaseolus vulgaris and Rhizobium etli strains with different degrees in nodulation efficiency. This approach identified conserved and known microRNAs (miRNAs) differentially accumulated in Mesoamerican P. vulgaris roots in response to a highly efficient strain, to a less efficient one or to both strains.

Project description:Fight-or-flight responses involve β-adrenergic-induced increases in heart rate and contractile force. Despite decades of investigations, predominantly focusing on ryanodine receptor and phospholamban phosphorylation, the molecular mechanisms underlying the sympathetic nervous system control of cardiac contractility remain controversial and incompletely elucidated. Here, we identify the calcium-channel inhibitor Rad as a critical component. In cardiomyocytes isolated from knock-in mice expressing Rad with alanine-substitutions of the four PKA-phosphorylated serine residues (4SA-Rad), calcium currents cannot be increased by adrenergic agonists or phosphatase inhibitor. In these mice, basal cardiac contractility, exercise capacity and heart rate are reduced, and the augmentation of contractile force by adrenergic agonists is severely blunted. Expression of mutant calcium-channel β-subunits that cannot bind Rad is sufficient to restore calcium influx and cardiac contractility in 4SA-Rad mice to levels induced by adrenergic agonists in wild-type mice, revealing a potential therapeutic approach to enhance cardiac contractility while bypassing stimulation of adrenergic receptors.
