Effects of benzothidiazole (BTH), an inducer of resistance, were examined in a compatible interaction of soybean seedlings and Phytophthora sojae using electron microscopy and quantitative real-time polymerase chain reaction (qRT-PCR) techniques. Seedlings were sprayed with BTH 2 days before inoculation of hypocotyls with zoospore suspension of P. sojae. In hypocotyls treated with BTH, the infection process of P. sojae was significantly delayed, and also the structures of hyphae and haustorium-like bodies were remarkably altered. These changes included increased vacuolation, plasmolysis, degeneration of cytoplasm, and collapse of hyphae and haustorium-like bodies. Large morphological differences were detected in P. sojae-infected hypocotyl tissue treated with BTH compared with infected but non-treated control tissue. Very thick layers of wall appositions were formed in the host cells contacting with hyphae, whereas such structures were never observed in only P. sojae-infected control hypocotyls. In addition, five pathogenesis-related (PR)-genes were selected to detect their transcription changes using qRT-PCR. Expression of PR-1, PR-3a, PR-3b, PR-9, and PR-10 genes were induced in BTH-treated and P. sojae-inoculated tissue at different times and levels. The up-regulated expression of these genes as well as the morphological defense structures may contribute to disease resistance in soybean hypocotyls to P. sojae.

Withania somnifera (L.) Dunal is a valued medicinal plant with pharmaceutical applications. The present study was undertaken to analyze the salicylic acid induced leaf transcriptome of W. somnifera. A total of 45.6 million reads were generated and the de novo assembly yielded 73,523 transcript contig with average transcript contig length of 1620 bp. A total of 71,062 transcripts were annotated and 53,424 of them were assigned GO terms. Mapping of transcript contigs to biological pathways revealed presence of 182 pathways. Seventeen genes representing 12 pathogenesis-related (PR) families were mined from the transcriptome data and their pattern of expression post 17 and 36 hours of salicylic acid treatment was documented. The analysis revealed significant up-regulation of all families of PR genes by 36 hours post treatment except WsPR10. The relative fold expression of transcripts ranged from 1 fold to 6,532 fold. The two families of peroxidases including the lignin-forming anionic peroxidase (WsL-PRX) and suberization-associated anionic peroxidase (WsS-PRX) recorded maximum expression of 377 fold and 6532 fold respectively, while the expression of WsPR10 was down-regulated by 14 fold. Additionally, the most stable reference gene for normalization of qRT-PCR data was also identified. The effect of SA on the accumulation of major secondary metabolites of W. somnifera including withanoside V, withaferin A and withanolide A was also analyzed and an increase in content of all the three metabolites were detected. This is the first report on expression patterns of PR genes during salicylic acid signaling in W. somnifera.
