Genetic diversity of Acidovorax oryzae in a single site in Mazandaran province, Iran.

Brown stripe, incited by Acidovorax oryzae is one of the most important and widespread diseases in rice (Oryza sativa) nurseries in Iran. Rice seedlings showing brown stripes were collected from suburb areas in southern Sari. Bacteria were isolated on plates of sorbitol neutral red agar.

Bioinformatic and empirical analysis of a gene encoding serine/threonine protein kinase regulated in response to chemical and biological fertilizers in two maize ( L.) cultivars.

Molecular structure of a gene, , encoding a serine/threonine protein kinase in maize was analyzed by bioinformatic tool and its expression pattern was studied under chemical biological fertilizers. Bioinformatic analysis cleared that is located on chromosome 10, from position 141015332 to 141017582. The full genomic sequence of the gene is 2251 bp in length and includes 2 exons.

Quantitative gene expression analysis of some sodium ion transporters under salinity stress in Aeluropus littoralis.

Plant sodium transporters activity is one of the most important salt tolerance mechanisms to keep normal status of cytosolic sodium content. In the present study, expression pattern of genes encoding Na(+)/H(+) antiporters in the plasma membrane (SOS1 gene), vacuolar membrane (NHX1 gene) and H(+)-ATPase pump (VHA gene) in Aeluropus littoralis under different treatments of NaCl was measured by the semi-quantitative RT-PCR method. Our results indicated that root and shoot sodium contents were increased along with increasing salinity pressure.
