Plant hemoglobins: Oxygen handlers critical for nitrogen fixation
Hemoglobins, key components of our blood, are ancient
proteins with well-known roles in oxygen transport and respiration in animals. Hemoglobins are also present in plants and bacteria, but until now the physiological role of plant hemoglobins has been unclear. A group of researchers reveal this week th...
