Recent reports suggest that early sensing of soil water stress by plant roots and the concomitant reduction in stomatal conductance may not be mediated by root-sourced abscisic acid (ABA), but that other xylem-borne chemicals may be the primary stress signal(s). To gain more insight into the role of root-sourced ABA, the timing and location of the(More)
Regulation of protein function through oxidative modification has emerged as an important molecular mechanism modulating various biological processes. Here, we report a proteomic study of redox-sensitive proteins in Arabidopsis cells subjected to H(2)O(2) treatment. Four gel-based approaches were employed, leading to the identification of four partially(More)
As class III unconventional myosins are motor proteins with an N-terminal kinase domain, it seems likely they play a role in both signaling and actin based transport. A growing body of evidence indicates that the motor functions of human class IIIA myosin, which has been implicated in progressive hearing loss, are modulated by intermolecular(More)
COG0354 proteins have been implicated in synthesis or repair of iron/sulfur (Fe/S) clusters in all domains of life, and those of bacteria, animals, and protists have been shown to require a tetrahydrofolate to function. Two COG0354 proteins were identified in Arabidopsis and many other plants, one (At4g12130) related to those of α-proteobacteria and(More)
Plants react to seasonal change in day length through altering physiology and development. Factors that function to harmonize growth with photoperiod are poorly understood. Here we characterize a new protein that associates with both circadian clock and photoreceptor components, named PHOTOPERIODIC CONTROL OF HYPOCOTYL1 (PCH1). pch1 seedlings have overly(More)
Tandem affinity purification coupled with mass spectrometry (TAP-MS) analysis is a powerful biochemical approach to identify protein-protein associations. Here we describe two datasets generated by a series of TAP-MS analyses to co-purify proteins associated with either ELF3 or ELF4 of the Evening Complex (EC) ("Identification of Evening Complex Associated(More)
Most of the budget for agricultural research‐for‐development is spent through projects and therefore project impact is important for funding agencies. Impact assessment is commonly performed ex‐post for the purpose of accountability and has provided little guidance to more effective project design and management. Here we present a project design that bases(More)
Making agriculture more competitive, resilient, and sustainable in developing countries requires continuous sharing of research processes and outcomes between farmers, development experts, scientists, and policymakers, among others. In recent years, new opportunities have emerged for research organizations to adopt innovative practices that foster knowledge(More)
