Ribosome profiling data report on the distribution of translating ribosomes, at steady-state, with codon-level resolution. We present a robust method to extract codon translation rates and protein synthesis rates from these data, and identify causal features associated with elongation and translation efficiency in physiological conditions in yeast. We show(More)
A great number of people spend one or more hours each day driving between home and the office. These daily roadway commutes are highly predictable and regular, and provide a great opportunity to form virtual mobile communities. However, even though these commuters are already physically present in the same location, they are limited in their ability to(More)
Distributed online social networks (DOSN) have been proposed as an alternative to centralized Online Social Networks (OSN). In contrast to centralized OSN, DOSNs do not have central repository of all user data, neither impose control regarding how users data will be accessed. Therefore, users can keep control of their private data and are not at the mercy(More)
A novel member of the WRKY gene family, designated TcWRKY53, was isolated from a cadmium (Cd)-treated Thlaspi caerulescens cDNA library by differential screening. WRKY proteins specifically bind to W-boxes, which are found in the promoters of many genes involved in defense and response to environmental stress. TcWRKY53 contains a 975-bp open reading frame(More)
In this paper, we propose a system for context- aware battery management that warns the user when it detects that the phone battery can run out before the next charging opportunity is encountered. At the heart of this system, are algorithms that predict: (1) when the next charging opportunity will be available, (2) how much call-time will be required by the(More)
Ca(2+)/calmodulin (CaM)-dependent protein kinase (CCaMK) is a key regulator of root nodule and arbuscular mycorrhizal symbioses and is believed to be a decoder for Ca(2+) signals induced by microbial symbionts. However, it is unclear how CCaMK is activated by these microbes. Here, we investigated in vivo activation of CCaMK in symbiotic signaling, focusing(More)
Compound leaf development requires highly regulated cell proliferation, differentiation, and expansion patterns. We identified loss-of-function alleles at the SMOOTH LEAF MARGIN1 (SLM1) locus in Medicago truncatula, a model legume species with trifoliate adult leaves. SLM1 encodes an auxin efflux carrier protein and is the ortholog of Arabidopsis thaliana(More)
Leaf shape elaboration and organ separation are critical for plant morphogenesis. We characterized the developmental roles of lobed leaflet1 by analyzing a recessive mutant in the model legume Medicago truncatula. An ortholog of Arabidopsis thaliana argonaute7 (AGO7), Mt-AGO7/lobed leaflet1, is required for the biogenesis of a trans-acting short interfering(More)
Salt and drought stresses often adversely affect plant growth and productivity, MYB transcription factors have been shown to participate in the response to these stresses. Here we identified a new R2R3-type MYB transcription factor gene TaMYB33 from wheat (Triticum aestivum). TaMYB33 was induced by NaCl, PEG and ABA treatments, and its promoter sequence(More)
Medicago truncatula has been developed into a model legume. Its close relative alfalfa (Medicago sativa) is the most widely grown forage legume crop in the United States. By screening a large population of M. truncatula mutants tagged with the transposable element of tobacco (Nicotiana tabacum) cell type1 (Tnt1), we identified a mutant line (NF2089) that(More)
