Progress and bottlenecks in the early domestication of the perennial oilseed Silphium integrifolium, a sunflower substitute
(MDPI, 2018-02)
Silflower (Silphium integrifolium Michx.) is in the early stages of domestication as a perennial version of oilseed sunflower, its close relative. Grain crops with deep perennial root systems will provide farmers with new ...
Ecosystem services for intensification of agriculture, with emphasis on increased nitrogen ecological use efficiency
(Wiley-Blackwell, 2020-02-01)
In weathered tropical soil, low nutrient use efficiency can lead to agricultural systems becoming unsustainable. Therefore, tropical agriculture is highly dependent on ecosystem services, such as nutrient recycling and ...
Long-term lime and gypsum amendment increase nitrogen fixation and decrease nitrification and denitrification gene abundances in the rhizosphere and soil in a tropical no-till intercropping system
(2020-10-01)
Liming is widely used to decrease soil acidity, and the application of lime alone or in combination with other amendments, such as gypsum, is a viable agricultural practice to improve soil nutrient status and crop yield. ...
The independent acquisition of plant root nitrogen-fixing symbiosis in Fabids recruited the same genetic pathway for nodule organogenesis
(Public Library of Science, 2013-05)
Only species belonging to the Fabid clade, limited to four classes and ten families of Angiosperms, are able to form nitrogen-fixing root nodule symbioses (RNS) with soil bacteria. This concerns plants of the legume family ...
An empirical model that uses light attenuation and plant nitrogen status to predict within-canopy N distribution and upscale photosynthesis from leaf to whole canopy
(2015-10-03)
Modelling the spatial and temporal distribution of leaf nitrogen (N) is central to specify photosynthetic
parameters and simulate canopy photosynthesis. Leaf photosynthetic parameters depend on both local light availability
and ...
Shifts in symbiotic associations in plants capable of forming multiple root symbioses across a long-term soil chronosequence
(John Wiley & Sons Ltd, 2016-04)
Changes in soil nutrient availability during long-term ecosystem development influence the relative abundances of plant species with different nutrient-acquisition strategies. These changes in strategies are observed at ...
Photosynthesis, Resource Acquisition and Growth Responses of Two Biomass Crops Subjected to Water Stress
(Science Publishing Group, 2018-06)
This study compares photosynthesis, growth, 13C and 15N labelling patterns of two biomass crops (Arundo donaxL. and Panicum virgatum L.) grown under water stress in greenhouse conditions. Plants were exposed to three water ...
