The Spatiotemporal Genetic Architecture of Seed Vigor in Upland Cotton

open access: yesAdvanced Science, EarlyView.
Leveraging the semi‐automated SeedRanger platform, we profiled the germination kinetics of 356 cotton accessions at a 30‐min interval. This high‐throughput phenomic approach delineated a temporal genetic network comprising 541 stage‐specific loci. Crucially, functional validation identified FLA2 as a pivotal, auxin‐modulated regulator that orchestrates

Weed seed-bank responses to long-term fertilization in a rice-wheat rotation system

open access: yesPlant, Soil and Environment, 2014
We studied the heterogeneity of soil weed seed-bank in a rice-wheat rotation system after long-term application of different organic or non-organic fertilizers, and the effects of major nutrients on the characteristics of the weed seed-bank. The soil was

Sustainable Productivity Growth in Agriculture: The Role of Shifts in R&D Investments and Technology

open access: yesApplied Economic Perspectives and Policy, EarlyView.
ABSTRACT The objective of the paper is to evaluate the long‐term prospects of sustainable productivity growth linked to plausible assumptions on public agricultural R&D investments as the key productivity driver. Second, it investigates the role of changing R&D focus from yield maximization to input saving technologies (fertilizers and pesticides). The

Rhododendron maximum impacts seed bank composition and richness following Tsuga canadensis loss in riparian forests

open access: yesEcosphere, 2018
Southern Appalachian riparian forests have undergone changes in composition and function from invasive pathogens and pests. Castanea dentata mortality in the 1930s from chestnut blight (Cryphonectria parasitica) and Tsuga canadensis mortality in the ...

Weed seed bank dynamics under various rotations and field production resources

open access: yesپژوهشهای زراعی ایران, 2009
Weed seed bank dynamics in corn, sugar beet and wheat plots in rotation with wheat were studied under conventional and ecological management systems during 2 years. The experiment was laid out in a split- plot design in a randomized complete block, where

VEGETATION AND SEED BANK IN RELATION TO MICROHABITAT OF WADI NAGHAMISH, NORTH WESTERN COAST OF EGYPT [PDF]

open access: yesEgyptian Journal of Desert Research, 2020
This study investigated the soil seed bank composition and standing vegetation over five different microhabitats (terraces, springs, wadi bed, saltmarshes and sand dunes) of a coastal ecosystem along the North Western Coast of Egypt.

How Competitive Is Myanmar's Rice Sector? A Comparison of Production Costs and Efficiency

open access: yesAgribusiness, EarlyView.
ABSTRACT This paper analyzes the cost competitiveness of rice production in Myanmar by examining production costs, cost efficiency, and the potential effect of improving cost efficiency on the country's global competitiveness. To achieve this, we conduct a comparative analysis of production costs among major rice‐producing countries and estimate the ...

The role of venture‐financed startups in innovation for US agriculture

open access: yesAmerican Journal of Agricultural Economics, EarlyView.
Abstract To evaluate the role played by startup companies in the innovation ecosystem of US agriculture, we compile a unique dataset of 6024 new entrants founded 1987–2019 that details their financing lifecycles, annual economic performance, and patenting activities.

Edaphic and seasonal heterogeneity of seed banks in agricultural fields of a tropical dry forest region in southern Mexico

open access: yesBotan‪ical Sciences, 2012
The slash-and-burn agriculture practiced across tropical dry regions results in the elimination of native vegetation. Upon field abandonment, the seed bank becomes a potentially important mechanism of natural regeneration at early successional stages ...

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 ...
