WebNov 11, 2024 · The first non-symbiotic hemoglobin was identified by Taylor in 1994 in barley . Subsequent studies identified several families of non-symbiotic hemoglobin. Class 2 non-symbiotic hemoglobins (subdivided into class 2a and class 2b) have low oxygen affinity [17,18] and, unlike class 1 hemoglobins, are not induced by hypoxia . WebThe northern blot analysis demonstrated that this gene is expressed in all organs, including the roots, hypocotyls, and leaves, with transcription levels increasing under flooding and high-sucrose conditions. However, cold treatment does not affect its expression pattern.

WebThe symbiotic hemoglobins were discovered in 1939 and are only found in nodules of plants capable of symbiotically fixing atmospheric N. Another class, called non-symbiotic hemoglobin, was discovered 32 yr ago and is now thought to exist throughout the plant kingdom, being expressed in different organs and tissues. WebSymbiotic hemoglobin (leghemoglobin) is a hemeprotein found in micromolar concentrations in infected cells of legume roots. This is an essential component for nitrogen fixation by legumes. Leghemoglobin is produced as a result of symbiotic association between bacteroid and plant.
