Vegetative Propagation of Species of Genus Allium L.

open access: yes, 1993
The genus Allium L. consists of about 500 species in the Northern hemisphere and includes a large number of useful plants. The highly variable underground organs of Allium species - rhizomes and bulbs - have the function of storing food and moisture in ...

A Conserved DT2‐bZIP66‐NF‐YC4 Regulatory Module Confers Drought Tolerance in Rice and Arabidopsis

open access: yesAdvanced Science, EarlyView.
This study identifies a conserved tripartiteDT2–bZIP66–NF‐YC4 transcriptional module that enhances rice drought tolerance by activating stress‐responsive genes. This regulatory complex is functionally conserved across cereals and Arabidopsis, providing promising targets for engineering drought‐resilient crops. ABSTRACT Drought stress severely restricts

Advancing European Plant Variety Registration: Data‐Driven Insights and Stakeholder Perspectives

open access: yesAgribusiness, EarlyView.
ABSTRACT Efficient plant variety registration is crucial for fostering innovation in the European Union, yet the current regulatory framework is complex and faces calls for reform. This study provides data‐driven evidence to inform the ongoing legislative debate by employing a mixed‐methods approach.

Cteno‐Bot: An Untethered Metachronally Swimming Robot With Magnetoactive Propulsors

open access: yesAdvanced Intelligent Systems, EarlyView.
We present Cteno‐bot, an untethered ctenophore‐inspired robot which swims using metachronally coordinated appendages. A single mechanism controls up to 216 magnetoactive propulsors via a dynamically varying magnetic field. We show that the swimming speed of the robot can be increased without a corresponding increase in power requirement, simply by ...

New perspectives in vegetative propagation

open access: yes, 1982
Most of the world's fruit trees, many ornamental plants, all the main root vegetables, and some forest trees are increased by vegetative propagation and not from seeds. Recent research has led to innovations that open up new prospects for this important

Seeds of change: The impact of Ethiopia's direct seed marketing approach on smallholders' seed purchases and productivity

open access: yesAmerican Journal of Agricultural Economics, EarlyView.
Abstract While multiple factors explain low adoption rates of improved varieties by small‐scale farmers in sub‐Saharan Africa, a key supply‐side constraint is the limited availability of seed embodying new traits in the volume, quality, price, and timeliness required by farmers. This constraint is partly attributable to classical failures in the market

Effect of cutting position in the mother plant and use of auxin on the rooting efficiency of cuttings in four varieties of Cannabis sp.

open access: yesAgricultura
The regulatory framework for the production, industrialization, and commercialization chain of Cannabis sp. plant, its seeds, and derived products for industrial and/or medicinal use has recently been approved in Argentina.

Costs and Benefits of Vegetative Propagation in the Desert Tulip

open access: yes, 1993
The effects of vegetative propagation on plant performance in the desert tulip Tulipa systola were studied experimentally. A differentiation was made between immediate effects (possible tradeoffs between vegetative propagation and seed production) and ...

Interactions between maternal provisioning and natural selection on seed mass fluctuate across heat waves

open access: yesAmerican Journal of Botany, EarlyView.
Abstract Premise Changing climates are leading to more frequent and severe heat waves, potentially threatening plant populations. Both acclimation to stress and selection for heat‐escape or heat‐resistance phenotypes occur during heat waves. However, plastic responses and selection do not necessarily interact cohesively—even producing trait responses ...
