A Wox3-patterning module organizes planar growth in grass leaves and ligules Open

James Satterlee, Lukas J Evans, Brianne R. Conlon, Phillip A. Conklin, Jesús Martínez‐Gómez , et al. · 2023

Grass leaves develop from a ring of primordial initial cells within the periphery of the shoot apical meristem, a pool of organogenic stem cells that generates all of the organs of the plant shoot. At maturity, the grass leaf is a flattene…

The Evolution of an Invasive Plant, Sorghum halepense L. (‘Johnsongrass’) Open

Andrew H. Paterson, Wenqian Kong, Robyn Johnston, Pheonah Nabukalu, Guohong Wu , et al. · 2020

From noble beginnings as a prospective forage, polyploid Sorghum halepense ('Johnsongrass') is both an invasive species and one of the world's worst agricultural weeds. Formed by S. bicolor x S. propinquum hybridizatio…

Plant homeodomain proteins provide a mechanism for how leaves grow wide Open

Phillip A. Conklin, Robyn Johnston, Brianne R. Conlon, Rena Shimizu, Michael J. Scanlon · 2020

The mechanisms whereby leaf anlagen undergo proliferative growth and expansion to form wide, flat leaves are unclear. The maize gene NARROWSHEATH1 (NS1) is a WUSCHEL-related homeobox3 (WOX3) homolog expressed at the margins of leaf primord…

A high-resolution gene expression atlas links dedicated meristem genes to key architectural traits Open

Steffen Knauer, Marie Javelle, Lin Li, Xianran Li, Xiaoli Ma , et al. · 2019

The shoot apical meristem (SAM) orchestrates the balance between stem cell proliferation and organ initiation essential for postembryonic shoot growth. Meristems show a striking diversity in shape and size. How this morphological diversity…

Monitoring the health of the Greater Mekong’s Rivers Open

Chris Dickens, Amy G. Cox, Robyn Johnston, Supatra Davison, Derin Henderson , et al. · 2018

The methods used for biomonitoring can be sophisticated, producing highly accurate results, but can also be simplified for communities to use. In countries where budgets for biomonitoring are low, using community-based biomonitoring system…

Experimental Design for Laser Microdissection RNA-Seq: Lessons from an Analysis of Maize Leaf Development Open

Robyn Johnston, Anne W. Sylvester, Michael J. Scanlon · 2017

Genes with important roles in development frequently have spatially and/or temporally restricted expression patterns. Often these gene transcripts are not detected or are not identified as differentially expressed (DE) in transcriptomic an…

Climate change and agricultural development: a challenge for water management. Open

Chu Thai Hoanh, Robyn Johnston, V. Smakhtin · 2015

Freshwater-related risks of climate change increase significantly with increasing global temperatures. Globally, the negative impacts of future climate change on freshwater systems are expected to outweigh the benefits, and agriculture and…

Restoring aboveground carbon and biodiversity: a case study from the Nile basin, Ethiopia Open

Wolde Mekuria, Simon Langan, Robyn Johnston, Beyene Belay, Dagninet Amare , et al. · 2015

In Ethiopia, exclosures in landscapes have become increasingly important to improving ecosystem services and reversing biodiversity losses. The present study was conducted in Gomit watershed, northern Ethiopia, to: (i) investigate the chan…

A Maize Glutaredoxin Gene,<i>Abphyl2,</i>Regulates Shoot Meristem Size and Phyllotaxy Open

Fang� Yang, Huyen Bui, Michael Pautler, Víctor Llaca, Robyn Johnston , et al. · 2015

Phyllotaxy describes the geometric arrangement of leaves and is important for plant productivity. Auxin is well known to regulate phyllotactic patterns via PIN1-dependent auxin polar transport, and studies of maize (Zea mays) aberrant phyl…

Integrated assessment of groundwater use for improving livelihoods in the dry zone of Myanmar. Open

Paul Pavelic, Sonali Senaratna Sellamuttu, Robyn Johnston, Matthew McCartney, T. Sotoukee , et al. · 2015

In the Dry Zone of Myanmar, improved access to water is widely acknowledged as being vital for livelihood enhancement and the general well-being of around 10 million people, most of whom depend on agriculture. Thus, expanding the sustainab…
