Present investigation was undertaken with an objective of establishment of cell suspension cultures of this plant which can be further used for in vitro production of desired secondary metabolites and their further scale-up. Seed dormancy was broken using sulfuric acid and seedlings were raised in vitro. MS medium supplemented with 2,4-D (0.5 mg/L) produced maximum callus from the nodal explants. The callus produced was used as an explant for the establishment of suspension cultures. MS medium without any supplement was proved best for the establishment of cell suspension cultures of H. isora .

Company (Pvt) Ltd. NARC, Islamabad in three ways i.e. rice seeds inoculated for direct seeding and nursery and dipping seedling roots in the solutions of these rhizobial strains comparable of control un-inoculated (control) by each inoculation method. The performances of Rhizobial strain Biozote–Max used as seed and seedling root dipping inoculation were superior to uninoculated control in all the parameters of the rice crop. Among the treatments, seed and seedling root dipping inoculation with Rhizobial strain Biozote–Max performed best in recording plant height, panicle length, number of tillers, 1000-grain weight and grain yield of rice crop. Maximum tillering was observed with all strains under different inoculation methods. Although, the strains performed better as compared to control, however, dipping of nursery roots produced significantly higher yield followed by seed inoculation for direct seeding. Overall, among all the inoculation methods seedling root dipping produced comparable paddy yield. The highest paddy yield (367 g m-2) was harvested with SBCC (M8) seed inoculation which was 13% more than that of un-inoculated (control).","PeriodicalId":146947,"journal":{"name":"Research in Plant Biology","volume":"55 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129495984","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Egyptian broomrape (Orobanche aegyptiaca) is a parasitic weed causing major yield loss in many field and vegetable crops and is a serious threat to Indian mustard. In this study, severalgenotypes of Indian mustard were screened in order to identify resistant genotypes against O. aegyptiaca. In the greenhouse conditions, genotypes were different in the degree of susceptibility to Broomrape. Attachment number, emergence number, and dry matter of parasitic broomrape were affected by biomass of genotype. A significant impact of the parasitism onto the dry weight of all infected mustard genotype with variable degree was observed. Broomrape attachment was observed in all the cultivated genotypes with Pusa mustard 24 being the most susceptible with the greatest number of emerged Orobanche shoots. In contrast, no emergence shoots were observed in four out of the fifteen genotype viz., Pusa Jaikisan, Pusa bold, Pusa Vijay and Pusa mustard 26 which have less attachment number and emergence number. These genotype appear to be interesting for our objectives.","PeriodicalId":146947,"journal":{"name":"Research in Plant Biology","volume":"46 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122303682","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Quality RNA in large quantity is often required in the analysis of gene expression. RNA extraction from samples collected from woody plants is generally complex, and becomes the main limitation to study gene expression, particularly in crops like Bixa orellana . Standard RNA extraction protocols are time consuming, laborious and cannot be adapted for high throughput functional analysis. Therefore a simple and effective protocol for extraction of high quality total RNA from bark tissue of woody stem was achieved using the RNeasy plant mini kit (Qiagen, USA). The extracted RNA was successfully converted into double-stranded cDNA using the SMATer cDNA synthesis kit (Clontech, USA) which is based on the S witching M echanism A t 5’ End of R NA T ranscript (SMART) technology. The integrity of the total RNA used for synthesizing double stranded cDNA was assessed agarose gel electrophoresis and by PCR. As expected, the PCR product contained the full coding sequence plus 69 and 196 bp of 5’ and 3’ UTRs respectively. The double-stranded cDNA was used successfully for creating a SSH cDNA library. The cDNA could also be useful for a number of other applications like cDNA library construction, EST analysis, RACE and Next Generation Sequencing (NGS).","PeriodicalId":146947,"journal":{"name":"Research in Plant Biology","volume":"38 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-06-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133553751","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
