Nodule-enhanced protease inhibitor gene: emerging patterns of gene expression in nodule development on Sesbania rostrata.
نویسندگان
چکیده
A novel marker for the early stages of nodulation of Sesbania rostrata was found to encode a putative member of the Kunitz family of protease inhibitors (SrPI1). Its expression was enhanced during nodulation, and was not up-regulated by wounding or upon infection with wide host-range pathogens. In situ expression patterns resembled those previously described for functions that may be implicated in delimiting infected nodule tissues from the rest of the plant. Thus, SrPI1 may be a component of a multi-layered barrier that restrains the invading rhizobia.

Nodule parenchyma-specific expression of the sesbania rostrata early nodulin gene SrEnod2 is mediated by its 3' untranslated region
The early nodulin Enod2 gene encodes a putative hydroxyproline-rich cell wall protein and is expressed exclusively in the nodule parenchyma cell layer. The latter finding suggests that the Enod2 protein may contribute to the special morphological features of the nodule parenchyma and to the creation of an oxygen diffusion barrier. The Enod2 gene of the stem-nodulating legume Sesbania rostrata (...

Leguminous plants in symbiosis with rhizobia form either indeterminate nodules with a persistent meristem or determinate nodules with a transient meristematic region. Sesbania rostrata was thought to possess determinate stem and root nodules. However, the nature of nodule development is hybrid, and the early stages resemble those of indeterminate nodules. Here we show that, depending on the env...

Upon submergence, Azorhizobium caulinodans infects the semiaquatic legume Sesbania rostrata via the intercellular crack entry process, resulting in lateral root-based nodules. A gene encoding a gibberellin (GA) 20-oxidase, SrGA20ox1, involved in GA biosynthesis, was transiently up-regulated during lateral root base nodulation. Two SrGA20ox1 expression patterns were identified, one related to in...
متن کاملA symbiotic plant peroxidase involved in bacterial invasion of the tropical legume Sesbania rostrata.
Aquatic nodulation on the tropical legume Sesbania rostrata occurs at lateral root bases via intercellular crack-entry invasion. A gene was identified (Srprx1) that is transiently up-regulated during the nodulation process and codes for a functional class III plant peroxidase. The expression strictly depended on bacterial nodulation factors (NFs) and could be modulated by hydrogen peroxide, a d...
متن کاملSrchi13, a novel early nodulin from Sesbania rostrata, is related to acidic class III chitinases.
On the tropical legume Sesbania rostrata, stem-borne nodules develop after inoculation of adventitious root primordia with the microsymbiont Azorhizobium caulinodans. A cDNA clone, Srchi13, with homology to acidic class III chitinase genes, corresponds to an early nodulin gene with transiently induced expression during nodule ontogeny. Srchi13 transcripts accumulated strongly 2 days after inocu...
