These three genetic pathways are believed to be part of a gene duplication event then recruited to work in nodulation.
12.
This shorter cycle time improves current efficiency as less short circuits occur and there is less nodulation of the cathode surface.
13.
Nodulation and nitrogen fixation are also highly correlated with soil pH . It performs better on acidic soils than alkaline soils.
14.
The current hypothesis about the evolution of the genes needed for nodulation is that they were recruited from other pathways after a polyploidy event.
15.
Leaf tissue senses the early nodulation events in the root through an unknown chemical signal, then restricts further nodule development in newly developing root tissue.
16.
Cells of the inner or outer cortex in the so-called " window of nodulation " just behind the developing root tip are induced to divide.
17.
There are a number of Rhizobium or mixing the rhizobium into the soil can combat poor nodulation and therefore improve the nitrogen fixing capacity of the chickpea.
18.
Effective nodulation takes place approximately four weeks after planting a crop, with the size, and shape of the nodules will depend on the crop that was planted.
19.
One of the main genes shown to be shared between the arbuscular mycorrhiza pathway and the nodulation pathway is SYMRK and it is involved in the plant-bacterial recognition.
20.
Nodulation is controlled by a variety of processes, both external ( heat, acidic soils, drought, nitrate ) and internal ( autoregulation of nodulation, ethylene ).
