Development and characterization of a Napier grass (Cenchrus purpureus Schumach) mapping population for flowering‐time‐ and biomass‐related traits reveal individuals with exceptional potential and hybrid vigor

open access: yesGCB Bioenergy, Volume 13, Issue 9, Page 1561-1575, September 2021., 2021
Napier grass is a promising feedstock for lignocellulosic biofuel production due to its superior biomass production and persistence. However, data supporting breeding efforts of Napier grass are scarce. Crosses were made between genetically distant parents with contrasting biomass traits.

Pest categorisation of Phenacoccus solenopsis

open access: yesEFSA Journal, Volume 19, Issue 8, August 2021., 2021
Abstract The EFSA Panel on Plant Health performed a pest categorisation of Phenacoccus solenopsis (Hemiptera: Pseudococcidae) for the European Union (EU) territory. This species is not included in EU Commission Implementing Regulation 2019/2072. P. solenopsis is native to North America and has spread to all continents except Antarctica. It has recently

Tandem DNA repeats contain cis‐regulatory sequences that activate biotrophy‐specific expression of Magnaporthe effector gene PWL2

open access: yesMolecular Plant Pathology, Volume 22, Issue 5, Page 508-521, May 2021., 2021
Expression of the effector gene PWL2 of the rice blast fungus is controlled by tandem repeat cis‐regulatory sequences in response to unknown signals from living cells of host (rice) or non‐host (onion). Abstract During plant infection, fungi secrete effector proteins in coordination with distinct infection stages.

Herbicide tolerance in 11 grass species for minimal‐to‐no‐mow golf course rough

open access: yesAgrosystems, Geosciences &Environment, Volume 4, Issue 3, 2021., 2021
Abstract Research was conducted to determine the tolerance of 11 grass species used in minimal‐to‐no‐mow turf areas to three postemergence herbicides applied at one‐ and twofold the maximum label rates in 2018 and 2019. Grasses were transplanted into field plots in West Lafayette, IN, in 2018 and 2019, allowed time to establish (∼1−2 mo), and then ...

Magnaporthe grisea Pathogenicity Genes Obtained Through Insertional Mutagenesis

open access: yesMolecular Plant-Microbe Interactions, 1998
We have initiated a mutational analysis of pathogenicity in the rice blast fungus, Magnaporthe grisea, in which hygromycin-resistant transformants, most generated by restriction enzyme-mediated integration (REMI), were screened for the ability to infect ...

Analysis of the Structure of the AVR1-CO39 Avirulence Locus in Virulent Rice-Infecting Isolates of Magnaporthe grisea

open access: yesMolecular Plant-Microbe Interactions, 2002
The AVR1-CO39 gene that came from a Magnaporthe grisea isolate from weeping lovegrass controls avirulence on the rice cultivar CO39. AVR1-CO39 was not present in the genome of the rice-infecting M. grisea isolate Guy11 from French Guyana, suggesting that

Why Conservation of Australian Native Temperate Grasslands Needs to Occur at Different Scales—From Landscapes to Patches, and From Governments to Individuals

open access: yesAustral Ecology, Volume 50, Issue 10, October 2025.
ABSTRACT Native temperate grasslands are among the most widespread biomes in Australia, and they have been extensively modified, primarily for livestock grazing and cropping on the fertile soils ideal for agriculture. In the 1980s and 1990s, foundational work by Jamie Kirkpatrick and others brought attention to the widespread loss of these ecosystems ...

Interactive effects of plant litter type and yak excrement on litter decomposition in a shrub‐encroached alpine meadow

open access: yesFunctional Ecology, Volume 39, Issue 7, Page 1799-1814, July 2025.
Read the free Plain Language Summary for this article on the Journal blog. Abstract In the plant community with a shrub–grass mosaic, the main types of litter include herbaceous litter and its mixed forms with shrub leaves and stems. However, the quantitative relationship between the litter composition type and the litter decomposition, as well as how ...

A Logistic Regression Model for the Prediction of Vegetation Recruitment in the Kinu River, Japan

open access: yesRiver Research and Applications, Volume 41, Issue 4, Page 786-796, May 2025.
ABSTRACT Vegetation overgrowth in rivers worldwide is a considerable problem because it can potentially reduce the flood‐flowing capacity and cause biodiversity loss. In this study, we developed a model to predict vegetation recruitment during the initial stages of secondary succession, which leads to vegetation overgrowth.

Species delimitation and molecular dating of southern African Tetramesa (Hymenoptera: Eurytomidae): An understudied microhymenopteran group

open access: yesAustral Entomology, Volume 64, Issue 2, May 2025.
Abstract The genus Tetramesa Walker (Hymenoptera: Eurytomidae) comprises over 200 species of herbivorous wasps that feed exclusively on grasses. Recent field surveys in South Africa for grass biological control programs have uncovered a large diversity of potential Tetramesa on African grasses.
