The developmental regulators that confer the identity of N-fixing root nodules belong to a transcription factor family (LSH) more commonly associated with defining the shapes of stems, flowers and ...

Visual assessment of the accuracy of the (semi) automatic segmentation of soybean nodule vasculature using Biomedisa’s smart interpolation algorithm. A research team used synchrotron-based X-ray ...

WEST LAFAYETTE, Ind. – Plant breeders could theoretically increase soybean crop yields if they could control the number of nodules on plant roots since they are responsible for fixing atmospheric ...

Legume plants regulate their symbiotic relationship with soil bacteria by using cytokinins—signaling molecules that are transmitted through the plant structure from leaves into the roots to control ...

Many leguminous plant species establish a symbiotic association with rhizobia that induces the formation of nodules on roots. This symbiosis enables nitrogen fixation in the nodules and is beneficial ...

Her greenhouse-grown soybean plants fix twice as much nitrogen from the atmosphere as their natural counterparts, grow larger and produce up to 36 percent more seeds. Tegeder designed a novel way to ...

The objectives of this study were (a): to define the effects of light, dark, and temperature on nodule activity (acetylene reduction), and (b) to establish the contributions of reserve carbohydrate ...

Plants need nitrogen to grow, but they can’t just grab it from the air like we do with oxygen. If the soil doesn’t have enough, farmers have to add fertilizers—an expensive and environmentally tricky ...

Nitrogenase-dependent acetylene reduction, nodule function, and nodule regrowth were studied during vegetative regrowth of harvested (detopped) alfalfa (Medicago sativa L.) seedlings grown in the ...

Cambridge scientists have identified two crucial genetic factors needed to produce specialised root organs that can accommodate nitrogen-fixing bacteria in legumes such as peas and beans. In a ...

A new study shows that legume plants regulate their symbiotic relationship with soil bacteria by using cytokinins—signaling molecules—that are transmitted through the plant structure from leaves into ...
