Abstract
Some strains of rhizobia produce a rhizobitoxine-induced foliar chlorosis on soybean, Glycine max (L.) Merr., and have a limited ability to nodulate the nodulation restrictive genotype (rj1). This study was undertaken to determine and compare the effect of chlorosisinducing or rj1-compatible strains and nonchlorosis-inducing strains on another legume, peanut (Arachis hypogaea L., cultivars ‘Starr’ and ‘Spancross’), in Leonard jar culture. Ten different rhizobial strains that induce chlorosis or nodulate rj1-plants, produced swellings at the nodulation sites on peanut roots. No rhizobial-induced chlorosis symptoms developed on either peanut cultivar. Control peanut plants inoculated with six different nonchlorosis-inducing strains of Rhizobium japonicum (Kirchner) Buchanan did not have swellings. The clustering of three distinctive characteristics, a) ability to nodule rj1 plants, b) the propensity to produce rhizobitoxine-induced chlorosis symptoms on soybean, and c) the ability to induce nodule-like swellings on peanut roots, in a common population of rhizobia suggests that these rhizobia may represent a taxonomically distinct group. These strains appear defective in their symbioses with both soybean and peanut, suggesting that they may have a symbiotic homology for a legume host other than either soybean or peanut.
