Draft Genome Sequence of Rhizobium tropici SARCC-755, a Free-Living Rhizobium That Nodulated and Promoted Growth in Pigeonpea [Cajanus cajan (L.) Millsp.].

SARCC-755 is a free-living soil bacterium that formed nodules on pigeonpea roots in the present study. However, the draft genome sequence reveals that this species contains the gene but lacks the common nodulation () genes and probably uses other pathways to induce nodules on the legume plant.

Near-isogenic lines of Triticum aestivum with distinct modes of resistance exhibit dissimilar transcriptional regulation during Diuraphis noxia feeding.

Russian wheat aphid (Diuraphis noxia, Kurdjumov) feeding on susceptible Triticum aestivum L. leads to leaf rolling, chlorosis and plant death - symptoms not present in resistant lines. Although the effects of several D.

Transcript profiling of wheat genes expressed during feeding by two different biotypes of Diuraphis noxia.

Diuraphis noxia (Kurdjumov)(Russian wheat aphid) has severe economic impacts on wheat and barley production in the United States. The interaction between the Russian wheat aphid and its cereal hosts is poorly understood. However, the recent appearance of new biotypes in the United States showed that specific interactions exist between wheat resistance loci and Russian wheat aphid biotypes.
