The overall goal of the Coastal Plants Genetics Program is to generate knowledge and technology to accelerate development of improved plant materials in native plant species for coastal restoration. Research is conducted in four differnt plants species: Smooth cordgrass (Spartina alterniflora), Sea oats (Uniola paniculata), Black mangrove (Avicennia germinans), and weedy red rice (Oryza sativa).
Recently, a few halophytes, in addition to the model plant Arabidopsis, have been used to understand the underlying physiological and genetic basis of salt tolerance.
Louisiana’s coastal wetlands play a vital role in the economy of both Louisiana and the United States because they support almost a third of the United States’ crude oil production and a large portion of the nation’s coastal fisheries. Louisiana’s wetlands are also vital because they host large populations of migratory birds and buffer the impact of hurricanes and storm surges.
At the plant stress molecular biology laboratory (PSMBL), we use molecular biology, genetics, and biotechnology tools for improving abiotic stress tolerance in rice and toward development of molecular markers for improvement of wetland plants to aid in coastal restoration efforts.
Development and evaluation of molecular markers for wetlands plant improvement.
We are researching ecologically important smooth cordgrass, which contributes to tidal marsh restoration and shoreline protection of the salt-marsh ecosystems, as a model grass halophyte and a salt-tolerant rice landrace "Pokkali" to identify salt-responsive novel/superior alleles and/or regulatory transcriptional machineries. Our ultimate goal is to translate the knowledge and exploit the resources toward development of salt-tolerant rice using molecular/precision-breeding techniques.

In the drought stress project, we are using rice as the model as well as target crop. Rice productivity is severely affected by water scarcity, especially when it occurs during essential periods of plant growth such as the reproductive stage.
