This study describes the establishment of cell suspension culture system and analysis of proline content of the selected rice genotypes under in vitro salt stress. The cell suspension cultures, initiated from the friable seed-derived callus, were established in MS medium supplemented with different concentrations of 2,4-D (0-25 μM) and subjected to different concentrations of NaCl (0-250 mM). The average Settled Cell Volume (SCV) of different clumps sizes was recorded. The results showed that MR219-4 exhibited the highest cell growth rate and regeneration capacity. The 750 μm sieved clumps have higher cell mass than the 500 and 250 μm sieved cell size. The shoot-regeneration capacity was maximum in 1/2 MS medium supplemented with 10 μM BAP. However, low regeneration capacity was obtained in NaCl treatments. MR219 (control) and MR219-9 appeared to be more NaCl tolerant than MR219-4. In addition, all genotypes significantly synthesized proline under NaCl conditions as demonstrated by the proline accumulation and MR219-4 revealed the lowest content among genotypes studied. These genotypes can be good model systems for studying the physiological mechanisms associated with in vitro selection for salt stress. This finding also suggests that proline may play a crucial role in protecting rice cells under salinity stress.","PeriodicalId":274901,"journal":{"name":"Asian Journal of Biotechnology","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131965640","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}

A total of 33 sequences were extracted from National Center for Biotechnological Information (NCBI) which include horseshoe crabs (Class: Merostomata), beetles (Class: Insecta), common crabs (Class: Melacostraca) and scorpion (Class: Arachnida) sequences. Constructed phylogram through comprehensive dry lab methodology using advanced software predictive tools showed that beetles are closely related with horseshoe crabs than common crabs (Class: Melacostraca). It was interesting to note that terrestrial Scorpion (Class: Arachnida) were distantly related to horseshoe crabs (Class: Merostomata). Phylogram and observed Genetic Distance (GD) data were also revealed that Limulus polyphemus was distantly related to all the other horseshoe crab species. Tachypleus gigas was closely related with Carcinoscorpius rotundicauda than with Tachypleus tridentatus. The observed mean Genetic Distance (GD) value was higher in 3rd codon position in all the selected group of organisms. Among the horseshoe crabs high GC content was observed in L. polyphemus (38.32%) and lowest was observed in T. tridentatus (32.35%). We conclude that COI sequencing (barcoding) could be used in identifying and delineating evolutionary relatedness with closely related species","PeriodicalId":274901,"journal":{"name":"Asian Journal of Biotechnology","volume":"96 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133289119","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}
