Research Summary:

The primary focus of the Bailey-Serres group at UCR is to define mechanisms of signal transduction and gene regulation that are critical to the response of plants to suboptimal environmental growth conditions. Our research is largely focused on mechanisms of sensing and response to cellular oxygen deprivation (hypoxia/anoxia) that is a major consequence of flooding, submergence or high metabolic activity (i.e., in meristems). We wish to understand the molecular and physiological processes that can enable plants to tolerate or escape an abiotic stress such as flooding, from the single cell to the whole plant level. This knowledge is of vital importance to efforts that seek to stabilize crop yields as the World's population grows, arable land decreases, and climatic patterns change.

Farmers of Bangladesh and India risk loosing over 4 million tons of rice each year to Monsoon floods. Fortunately, flood resilient rice has become a reality due to the identification of a naturally occurring rice gene that helps rice that is completely submerged survive a prolonged period of time underwater. New rice varieties have been bred for submergence tolerance and provided freely to farmers, primarily through the initiatives of the International Rice Research Institute.

Our team has elucidated the mechanism of function of the rice SUB1A gene that is used to alleviate crop loss due to complete submergence in Asia. We have also uncovered low oxygen sensing and response mechanisms that enable survival for a short period of oxygen deprivation in the model plant Arabidopsis. We have also studied extensively the regulation of gene expression that occurs after a gene transcript is produced, as the modulation of mRNA translation and storage provides a means to conserve energy when cells are deprived of oxygen. We use molecular-genetic, biochemical, chemical genomics and systems-biological approaches to study these processes. As much as possible, we seek to understand what occurs in specific cells, such as those of the root cortex or leaf mesophyll, to provide the plasticity necessary for survival. The long-term goal is to increase crop tolerance of flooding / submergence, combine stress tolerances, and to contribute to the general understanding of low-oxygen sensing and gene regulation in eukaryotic cells.

Current Lab Projects:

Sub1 Rice Projects: Submergence tolerance and anaerobic germination tolerance in rice and maize – Funded by the National Science Foundation (NSF IOS-1121626) and Molecular dissection of the quiescence strategy conferred by SUB1A in rice under submergence and drought. (NIFA 2011-04015) Researchers: Erin Brinton, Rejbana Alam, Ngoc Huynh, Kristina Schreiber, Anna Locke, Ngoc Huynh, Cynthia Larive (UCR Chemistry), Takeshi Fukao (Virginia Tech).

Low oxygen sensing and response mechanism studies, including continuation of our analysis of proteins of unknown function of Arabidopsis. Researcher: Travis Lee.

mRNPome Project: An Arabidopsis 2010 Project focused on identification and characterization of RNA binding proteins that contribute to post-transcriptional gene regulation in plants (National Science Foundation, MCB-1021969). Using genetics and biochemistry we are capturing and characterizing the RNAs associated with specific RNA binding proteins. Researchers: Reed Sorensen, Maureen Hummel, Lauren Dedow, George Chantarachot, Thomas Girke (UC Riverside); Leslie Sieburth (University of Utah).

The translatome and beyond: Much gene regulation occurs at the cell specific and post-transcriptional levels. The Bailey-Serres lab has developed methods for analysis of mRNA associated with ribosomes or specific RNA binding proteins in individual cell types. Data for cell-specific translatomes of Arabidopsis can be viewed at http://efp.ucr.edu/. Methods for translatome isolation are available by download or request. Many of the Arabidopsis lines we developed for translating ribosome affinity purification (TRAP) are available through ABRC. Our methods for profiling ribosome footprints (Ribo-Seq) will be made available soon. Researchers: Jérémie Bazin, Reed Sorenson, Maureen Hummel.

Plasticity Project: An NSF-PGRP project (MCB-1238243) that will develop and apply technology in rice, tomato and Medicago to study responses to drought and submergence. Our collaborators are the Brady and Sinha labs at UC Davis and the Deal lab at Emory University. We are developing nuclear isolation (INTACT) and ribosome immunopurification (TRAP) technologies in these species. Researchers: Germain Pauluzzi and Mauricio Reynoso.
