Uptake hydrogenase in Rhizobium is a desirable attribute of the bacterium to prevent plant energy losses during symbiosis. Comparative inoculation studies with H<sub>2</sub>-uptake positive (Hup<sup>+</sup>) and H<sub>2</sub>-uptake negative (Hup<sup>-</sup>) strains in soybean, pea and ’cow pea group’ hosts have shown anomalies from significant differences in plant weight and plant nitrogen to non-significant differences in the effectivity. However, in cow pea where non-significant difference in effectivity has been observed, the Hup<sup>+</sup> 展开更多
