View article: Success and limitations in adaptation of Fast-TrACC tissue culture-independent transformation in coffee, cotton, and tree tobacco
Success and limitations in adaptation of Fast-TrACC tissue culture-independent transformation in coffee, cotton, and tree tobacco Open
Plant transformation is a critical process for generating transgenic and genome-edited plants for use in research and agriculture. For most plant species, this process has traditionally involved genomic insertion of DNA in tissue culture a…

Catechol acetylglucose: a newly identified benzoxazinoid‐regulated defensive metabolite in maize Open
Summary An enormous diversity of specialized metabolites is produced in the plant kingdom, with each individual plant synthesizing thousands of these compounds. Previous research showed that benzoxazinoids, the most abundant class of speci…

Knockout mutations of<i>Nicotiana benthamiana</i>defenses reveal the relative importance of acylsugars, nicotine, and a serine protease inhibitor in a natural setting Open
Summary Plants produce an immense diversity of defensive specialized metabolites. However, despite extensive functional characterization, the relative importance of different defensive compounds is rarely examined in natural settings. Here…

Fatty alcohols, a minor component of the tree tobacco surface wax, are associated with defence against caterpillar herbivory Open
Despite decades of research resulting in a comprehensive understanding of epicuticular wax metabolism, the function of these almost ubiquitous metabolites in plant–herbivore interactions remains unresolved. In this study, we examined the e…

Fatty Alcohols, a Minor Component of the Tree Tobacco Surface Wax, Reduce Insect Herbivory Open
Despite decades of research resulting in a comprehensive understanding of epicuticular wax biosynthesis and metabolism, the function of these almost ubiquitous metabolites in plant-herbivore interactions remains unresolved. To develop a be…

Cuticular Wax Composition is Essential for Plant Recovery Following Drought with Little Affect under Optimal Conditions Open
Despite decades of extensive study, the role of cuticular lipids in sustaining plant fitness is far from being understood. To answer this fundamental question, we employed genome editing in tree tobacco ( Nicotiana glauca ) plants and gene…

Mesophyll Abscisic Acid Restrains Early Growth and Flowering But Does Not Directly Suppress Photosynthesis Open
Abscisic acid (ABA) levels increase significantly in plants under stress conditions, and ABA is thought to serve as a key stress-response regulator. However, the direct effect of ABA on photosynthesis and the effect of mesophyll ABA on yie…
View article: Role of guard-cell ABA in determining maximal stomatal aperture and prompt vapor-pressure-deficit response
Role of guard-cell ABA in determining maximal stomatal aperture and prompt vapor-pressure-deficit response Open
Abscisic acid (ABA) is known to be involved in stomatal closure. However, its role in stomatal response to rapid increases in the vapor pressure deficit (VPD) is unclear. To study this issue, we generated guard cell (GC)-specific ABA-insen…
View article: Shoot stem cell specification in roots by the WUSCHEL transcription factor
Shoot stem cell specification in roots by the WUSCHEL transcription factor Open
The WUSCHEL homeobox transcription factor is required to specify stem-cell identity at the shoot apical meristem and its ectopic expression is sufficient to induce de novo shoot meristem formation. Yet, the manner by which WUS promotes ste…
