Brassinosteroids (BRs) are essential phytohormones regulating normal plant growth and development. TCP1, a gene thought to be involved in floral organ symmetric control, was identified as a genetic suppressor of a weak BR receptor mutant, bri1-5, in an activation-tagging genetic screen. TCP1 encodes a putative transcription factor possessing a basic(More)
Large-scale public cloud providers invest billions of dollars into their cloud infrastructure and operate hundreds of thousands of servers across the globe. For various reasons, much of this provisioned server capacity runs at low average utilization, and there is tremendous competitive pressure to increase utilization. Conceptually, the way to increase(More)
BAK1 and BKK1 are two functionally redundant leucine-rich repeat receptor-like protein kinases (LRR-RLKs) involved in brassinosteroid signal transduction by their direct interactions with the BR receptor, BRI1. Recent studies from our group and others indicated that the two RLKs also play critical roles in regulating pathogen-related and pathogen-unrelated(More)
Brassinosteroids (BRs) are a group of major phytohormones playing critical roles in plant growth and development. Within the last two decades, key events of BR biosynthesis and signal transduction have been gradually elucidated. The detailed molecular mechanisms controlling bioactive levels of BRs, however, are not fully understood. TCP1 is a member of(More)
Dicer-mediated processing of virus-specific dsRNA into short interfering RNAs (siRNAs) in plants and animals initiates a specific antiviral defense by RNA interference (RNAi). In this study, we developed a forward genetic screen for the identification of host factors required for antiviral RNAi in Arabidopsis thaliana Using whole-genome sequencing and a(More)

As the increasing demands of large-scale data analytics, the understanding of performance bottlenecks on big data workloads becomes critical for the optimization of distribution platforms. Existing work focused on qualitatively characterizing the behaviors and performance of workloads. However little effort has been spent on quantification of performance(More)
