Haplotype-resolved genome assembly of ‘Manhattan’ perennial ryegrass (Lolium perenne L.) and characterization of drought responsive late embryogenesis abundant genes

Matthew D. Robbins, B. Shaun Bushman, Joseph P. Gallagher, Peter J. Maughan et autres

BACKGROUND: Perennial ryegrass is a premier forage and turf grass, a genomic model organism for cool-season perennial grasses, but has relatively poor persistence under drought stress. The cultivar 'Manhattan' is an heirloom turf-type cultivar, and ancestral to many current turf cultivars and …

Measuring genetic diversity of Texas bluegrass and allele sharing with Kentucky bluegrass interspecific hybrids using genome-wide markers

Nicholas A. Boerman, Matthew D. Robbins, Ambika Chandra, Tom Brentano et autres

Kentucky bluegrass is an important cool-season turfgrass species. However, heat and drought tolerance is an issue. Interspecific hybridization with a related species, Texas bluegrass, is an approach used to improve heat and drought tolerance. We report herein a contig assembly and annotation …

Fructan biosynthesis gene expression upon cold acclimation in orchardgrass (Dactylis glomerata L.)

B. Shaun Bushman, Joseph G. Robins, Xinxin Zhao, Guangyan Feng et autres

Abstract Background Fructan content and flux in temperate forages can benefit the grasses through increased cold hardiness, increased drought tolerance, and improved forage quality. Orchardgrass (Dactylis glomerata L., or cocksfoot) produces relatively long and unbranched levan‐type fructans, but the genes involved in …

Dual Mechanisms of Salinity Tolerance in Wheat Germplasm Lines W4909 and W4910

Richard R.‐C. Wang, Steven S. Xu, Thomas A. Monaco, Matthew D. Robbins

Soil salinity adversely affects plant growth and development, reducing the yield of most crops, including wheat. The highly salt-tolerant wheat germplasm lines W4909 and W4910 were derived from a cross between two moderately salt-tolerant lines, the Chinese Spring (CS)/Thinopyrum junceum disomic addition …

Prediction of Turfgrass Quality Using Multispectral UAV Imagery and Ordinal Forests: Validation Using a Fuzzy Approach

Alexander J. Hernández, Shaun Bushman, Paul A. Johnson, Matthew D. Robbins

Protocols to evaluate turfgrass quality rely on visual ratings that, depending on the rater’s expertise, can be subjective and susceptible to positive and negative drifts. We developed seasonal (spring, summer and fall) as well as inter-seasonal machine learning predictive models of turfgrass …

Mapping Floral Resources in Montane Landscapes Using Unmanned Aerial Systems and Two-step Random Forest Classifications

Jesse Tabor, Alexander J. Hernández, Diana Cox-Foster, Byron Love et autres

Monitoring floral biodiversity is a critical step in understanding terrestrial ecosystems. However, manual methods to quantify flowering vegetation are costly in time and personnel. In large landscapes, these limited methods may not capture the spatial and temporal variation of floral resources. Recent …

Late‐heading parental selection in orchardgrass (Dactylis glomerata L.)

Megan M. Getz, Matthew D. Robbins, Kimberly Thorsted, Kevin B. Jensen et autres

Abstract Dactylis glomerata L., orchardgrass or cocksfoot, is frequently planted as a companion crop in perennial forage legumes such as alfalfa (Medicago sativa L.). However, many commercial orchardgrass cultivars flower earlier than legumes, resulting in a reduction in grass yield and nutritional …

Association of hard fescue (Festuca brevipila) stress tolerances with genome mapped markers

B. Shaun Bushman, Matthew D. Robbins, Yinjie Qiu, Eric Watkins et autres

Abstract Hard fescue is an allo‐hexaploid, caespitose, cool‐season grass that is part of the fine‐leaved ovina complex of the Lolium–Festuca clade in Poaceae. It is predominantly used as a low‐maintenance turfgrass and soil stabilization grass in situations with reduced inputs of nitrogen …

Experiences in the high throughput phenotyping of forage and turf grasses for semiarid landscapes: challenges and expectations

Alex Hernandez, Kevin B. Jensen, Steven R. Larson, Shaun Bushman et autres

The Forage and Range Lab (FRRL) is implementing a high throughput phenotyping (HTP) project using unmanned aerial vehicles (UAV), multispectral sensors, and programmatic pipelines for computational automation. Here we report on different HTP experiences for forage and turf grasses. Phenotypic traits (plant …

Homoeologous evolution of the allotetraploid genome of Poa annua L.

Christopher W. Benson, Matthew R. Sheltra, Peter J. Maughan, Eric N. Jellen et autres

BACKGROUND: Poa annua (annual bluegrass) is an allotetraploid turfgrass, an agronomically significant weed, and one of the most widely dispersed plant species on earth. Here, we report the chromosome-scale genome assemblies of P. annua's diploid progenitors, P. infirma and P. supina, and …
