nodulation การใช้

• Little information is available concerning the mechanisms leading to nodulation.
• The flowers are classically root nodulation is very common.
• Predicting gene regulatory networks of soybean nodulation from RNA-Seq transcriptome data.
• These may well constitute the evolutionary precursors in legumes for nitrogen fixation through nodulation.
• Autoregulation of nodulation controls nodule numbers per plant through a systemic process involving the leaf.
• Several different pathways have been implicated as donating duplicated genes to the pathways need for nodulation.
• These traits include enhanced  competitive nodulation, nodule development, intracellular infection, and bacteroid persistence.
• As in legumes, nodulation is favored by nitrogen deprivation and is inhibited by high nitrogen concentrations.
• Nodulation is rare in this subfamily, and where it does occur, nodules have a primitive structure.
• Regulation of nodule meristems utilizes long distance regulation commonly called " Autoregulation of Nodulation " ( AON ).
• These three genetic pathways are believed to be part of a gene duplication event then recruited to work in nodulation.
• This shorter cycle time improves current efficiency as less short circuits occur and there is less nodulation of the cathode surface.
• Nodulation and nitrogen fixation are also highly correlated with soil pH . It performs better on acidic soils than alkaline soils.
• The current hypothesis about the evolution of the genes needed for nodulation is that they were recruited from other pathways after a polyploidy event.
• 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.
• Cells of the inner or outer cortex in the so-called " window of nodulation " just behind the developing root tip are induced to divide.
• 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.
• 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.
• 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.
• Nodulation is controlled by a variety of processes, both external ( heat, acidic soils, drought, nitrate ) and internal ( autoregulation of nodulation, ethylene ).
