Sodium—A Functional Plant Nutrient
An array of evidence and arguments are presented to support the classification of Na as a “functional nutrient,” including its requirement for maximal biomass growth for many plants and its demonstrated ability to replace K in a number of ways. Expand
Biological nitrification inhibition (BNI)—is it a widespread phenomenon?
It is suggested that the BNI capacity could either be managed and/or introduced into pastures/crops with an expression of this phenomenon, via genetic improvement approaches that combine high productivity along with some capacity to regulate soil nitrification process. Expand
Evidence for biological nitrification inhibition in Brachiaria pastures
These findings provide direct evidence for the existence and active regulation of a nitrification inhibitor (or inhibitors) release from tropical pasture root systems, and could become a powerful strategy toward the development of low-nitrifying agronomic systems, benefiting both agriculture and the environment. Expand
A bioluminescence assay to detect nitrification inhibitors released from plant roots: a case study with Brachiaria humidicola
The proposed bioluminescence assay can be used to characterize and determine the BNI activity of plant roots, thus it could become a powerful tool in genetically exploiting the B NI trait in crops and pastures. Expand
NH4+ triggers the synthesis and release of biological nitrification inhibition compounds in Brachiaria humidicola roots
Results indicate that the release of BNI-compounds from B. humidicola roots is a regulated function and that presence of NH4+ in the root environment is necessary for the sustained synthesis and release ofBNI. Expand
Detection, isolation and characterization of a root-exuded compound, methyl 3-(4-hydroxyphenyl) propionate, responsible for biological nitrification inhibition by sorghum (Sorghum bicolor).
Methyl 3-(4-hydroxyphenyl) propionate is the first compound purified from the root exudates of any species; this is an important step towards better understanding BNI in sorghum. Expand
Importance of active oxygen-scavenging system in the recovery of rice seedlings after submergence
The data reveal the involvement of active oxygen-scavenging system during recovery of submerged rice seedlings under excessive illumination and ensures a better operation of ascorbic acid–glutathione cycle that helps detoxify H 2 O 2 more efficiently in FR13A. Expand
Physiological evaluation of responses of rice (Oryza sativa L.) to water deficit
Visual scoring to assess damage was found to be a reliable measure of tolerance for water deficit in rice cultivars tolerant of mild water stress and enabled tolerant cultivars to maintain high moisture in the leaf and to have high values of leaf area, shoot dry matter, and sugar and starch in tissues in stressed plants relative to the control. Expand
Free fatty acids from the pasture grass Brachiaria humidicola and one of their methyl esters as inhibitors of nitrification
The tropical pasture grass, Brachiaria humidicola (Rendle) Schweick, produces nitrification inhibitory compounds (termed biological nitrification inhibitors or BNIs) in its shoot and root tissues andExpand
SUMMARY The assimilation and distribution in Azolla pinnata of nigrogen from three different sources of nitrogen–ammonium, nitrate and dinitrogen–were compared. Neither ammonium nor nitrate suppliedExpand
