Abstract/Contents:"Eleusine indica (goosegrass) is one of a most common and troublesome weed in turfgrass and agriculture. It quickly adapts to environmental condition, human activities and harmful chemicals. To study the diversity of goosegrass in different environment setting we evaluated ten different population of E. indica collected from managed turfgrass, non-crop, and crop environments. A common-garden experiment was conducted for two years, and different phenotypic characteristic like length from base to last leaf on stem, length from base to terminal spikelet cluster, number of spikelets per seedhead, leaf length of the third leaf from the plant base, length between second and third leaves on stem, leaf width of the third leaf from the base of the plant (leaf width), and angle of stems from soil (stem angle) were measured to understand the plant architecture of these populations. Principal component analysis (PCA) using data from morphological traits suggest that the population can be divided to divide the population into three groups 1) population collected from crop environment, 2) population collected from non-crop and most of managed turfgrass, and 3) a single population (Texas-GCPG), a dwarf ecotype collected from golf course putting green area. Additionally, response to different plant growth regulator on subset of these populations suggest that the adaptation of Texas-GCPG in golf course putting green environment might be due to alteration in gibberellin biosynthesis pathway which is supported by gibberellin analysis of wild type goosegrass and Texas-GCPG. Epigenomic modification that impact gene expression helps plant species with acclimation to new environment through phenotypic plasticity which can be transgenerational and act as buffer for genome to generate new mutation to adapt to the new environment. Our findings do somewhat support this hypothesis that needs further investigation through gene expression and epigenetic evaluation of goosegrass population collected from different environmental condition."
