Sinorhizobium fredii USDA257 releases a 22-kDa outer membrane protein (Omp22) to the extracellular milieu when grown in calcium-limiting conditions.

Molecular plant-microbe interactions : MPMI - 1 Aug 2005

Abstract excerpt

Calcium, which regulates a wide variety of cellular functions, plays an important role in Rhizobium-legume interactions. We investigated the effect of calcium on surface appendages of Sinorhizobium fredii USDA257. Cold-field emission scanning electron microscopy observation of USDA257 grown in calcium-limiting conditions revealed cells with unusual shape and size. Transmission electron microscopy observation...
