Bacillus Thuringiensis
Hi Erkad. I was just wondering why you changed one of my Bacillus Thuringiensis edits. I thought it read clearer the way I had it. AIRcorn (talk) 06:15, 10 February 2010 (UTC)                                                                       Hi AIRcorn. I found time for reply.Sorry for delay.First of all it is very strange to me ,that you "now is writing a report at the moment about Bt and other pesticides " have been use  only Google Scholar  as a source for evaluation  of  scholarly research  contribution to the academic field for Zakharyan R.A.    For this it was necessary also  go to  original articles published  by prominent scientists in the field... Articles : Zakharyan R.A.et al.

In 2003 Zakharyan's 1976 paper was referenced in book edited by R.K. Upadhyay(see above). In 006 Zakharyan"s 1976 paper was referenced in Review : Entomological Journal of East CHINA:XU Jian, LIU Qin, YIN Xiang-dong and ZHU Shu-de (2006). "A review of recent development of Bacillus thuringiensis ICP genetically engineered microbes". Entomological Journal of East China 15 (1): 53–58.. AIRcorn, Now read what are saying in scientific press scientist  with the  outstanding contribution in the BT,  Dean D.H., Clayton C. Beegle , Takhashi Yamamoto in their review  articles about Zakharyan's 1976,1979 work and discovery (see above):exact the words and phrase that you have removed  from text and articles from references:"Zakharyan R. A.(1976,1979) first reported the presence of plasmids in B.thuringiensis and suggested involvement of the plasmids in endospore/crystal formation,also described the presence of large plasmid in Cry+ variant of B.thuringiensis."; and also look XU Jian et al. article(2006)(Zakharyan R.A. 1976); and other authors.

Zakharyan's name has been presented  among names of 26 scientists evalueted with landmark work in Bt. since 1901( I.S.Ishiwata's discovery). So,the information that you have and provided to Smartse" that information to you comes  up very little  and that paper(you presented just only one, Landen R et al.) does mention him (Zakharyan) also mentions others" and other statements are irrelevant, and the statement mentioned by you to Smartse that"His 1979 paper seems to be the most cited" and only "can be used as a reference" also irrelevant  and I am sure because of lack of good information. The discovery of plasmids in Bt and experimental evidence suggested involvement of the plasmids in endospore /crystal formation by Zakharyan R.A. was followed by intensive research to characterise plasmids and determine their role in Bt-endotoxin production, followed by growing Bt -recombinant technology and industry.In this way remarkable and outstanding work was done by J. Gonsales ,H.E.Schnepf and H.R.Whiteley. And one more,articles in Wikipedia to be more encyclopedic should include names and even photo of #1 contributors in the field.I am looking forward to see   new version of  your article  asap.Erkad,talk. Hi AIRcorn, In article Bt I did small change 1979 to 1976.Thank's for prompt answer.Erkad,talk.
 * I have copied your response from Smartse's talk page and replied to it. I am also in the process of updating the Bacillus Thuringiensis article. Cheers AIR corn (talk) 07:17, 24 February 2010 (UTC)

Hi AIRcorn, In article Bt I did small change 1979 to 1976.Thank's for prompt answer.Erkad,talk.

Hi AIRcorn,to be consistent in Bt. "Discovery and Study" please consider, that the enormous progress in Bt -recombinant technology followed by today's Bt.-industry was a result of a discovery of plasmids and a large one identified in Cry+ strain with evidence suggesting that crysal protein is specified by plasmid DNA (Zakharyan 1976,1979), discovery that a large plasmid has been associated with crystal protein production( Gonzales JM et al. 1981. Correlation between specific plasmids and endotoxin production in Bt. Plasmid 5,351-365.), and recombinant technology successfuly was applied for cloning crystal toxin gene (Schnepf H.E. and Whiteley H.R. 1981. Cloning and expression of the Bt. crystal protein gene in E.coli. Proc.Natl.Acad. Sci. USA 78,2893-2897.). Facts speak for themselves.Cheers Erkad (talk).tures|unsigned]] comment added by Erkad (talk •
