The RT reaction was performed at 50°C for 30 min, followed by PCR amplification at 94°C for 2 min for 1 cycle; 94°C for 35 s, 55-58°C for 30 s, and 72°C for1.0 min for 28 cycles; and 72°C for 10 min for 1 cycle. Microarray data accession The microarray data from this study is available on the GEO database at http://www.ncbi.nlm.nih.gov/geo under series GSE14625, GSE14983, and GSE14998.

Electronic supplementary material Additional file 1: Table of differential expressed genes. This Excel file contains all differentially expressed genes under effect of bean leaf, pod extract, and apoplastic fluid. The table contains 224 genes that showed
± 1.5 fold change in expression level. Comparative analysis was performed and the genes were grouped in accordance with similar responses. The group A comprises differential expressed genes in response to three plant extracts. Group B include genes in response to bean leaf extract selleck chemicals llc and apoplastic fluid. Group C include genes in response to apoplastic fluid and bean pod extract. The group D, E and F comprises genes in particular responses to bean leaf extract, apoplastic fluid and bean pod extract respectively. The file includes a Venn diagram that shows the relations between the responses to three plant extracts. (XLS 109 KB) Additional file 2: see more Table of differential
expressed genes with the more stringent cut-off. The table contains 121 genes with ± 2.0 fold change in expression level. These genes were grouped according to the function, and then clustered based on the kind of plant extract using the complete linkage cluster algorithm. The cluster of induced and repressed genes that are discussed in manuscript and a comparative Venn diagram are also shown. (XLS 125 KB) References 1.
