My First...

Yeah! Long silence! This is the reason! Adobe photoshop..Microsoft Power point ..Microsoft word..pdf..ppt..doc files...These stupid guys are just driving me nuts..…just one month to go for the summer vacation….deadline for two article submission ..Hmm! Phd is really not easy..may be I should have believed my friends and family…research may be not my cup of coffee…my confidence level is almost hanging close to zero…..got a small encouragement. my first research article (after joining phd) got published this month. Yeah! Its Anton’s paper, if you carefully search my name among the 27 authors in the below abstract, you will find my name in the 10th position….

After naming my blog as "Diatomist" I should write something about diatoms right? so here it is...

Title:

Identification and comparative genomic analysis of signaling and regulatory components in the diatom Thalassiosira pseudonana

Diatoms are unicellular brown algae that likely arose from the endocytobiosis of a red alga into a single-celled heterotroph and that constitute an algal class of major importance in phytoplankton communities around the globe. The first whole-genome sequence from a diatom species, Thalassiosira pseudonana Hasle et Heimdal, was recently reported, and features that are central to diatom physiology and ecology, such as silicon and nitrogen metabolism, iron uptake, and carbon concentration mechanisms, were described. Following this initial study, the basic cellular systems controlling cell signaling, gene expression, cytoskeletal structures, and response to stress have been cataloged in an attempt to obtain a global view of the molecular foundations that sustain such an ecologically successful group of organisms. Comparative analysis with several microbial, plant, and metazoan complete genome sequences allowed the identification of putative membrane receptors, signaling proteins, and other components of central interest to diatom ecophysiology and evolution. Thalassiosira pseudonana likely perceives light through a novel phytochrome and several cryptochrome photoreceptors; it may lack the conserved RHO small-GTPase subfamily of cell-polarity regulators, despite undergoing polarized cell-wall synthesis; and it possesses an unusually large number of heat-shock transcription factors, which may indicate the central importance of transcriptional responses to environmental stress. The availability of the complete gene repertoire will permit a detailed biochemical and genetic analysis of how diatoms prosper in aquatic environments and will contribute to the understanding of eukaryotic evolution.

Neither End note nor Refworks or any other damn bibiliogrpahic software would support adding your paper when I refer to it...come on, even English has got only 26 alphabets and you have a paer with 27 authors......OMG

well, anyway , I found your paper rubbish :-( though you are sweet
;-)

Who is that anonymous…..who don’t know to appreciate the team work? ;-) What does the buffaloes in the previous blog video teach us? People from four continents got united in the name of diatoms… what else have such a strong bidding capacity? Hmm..Hmm..tell..Me…??? Its rubbish??? Thanks for boosting my confidence :-( :-(

Ummms! u r in ur 2nd year Ph.D & already have 4 publications & submitting two more this month (inspite of all ur travels) …u r just doing g8!

Wtz the confidence level score now ;-)

Hmmmm!... 1.5 :-(

Be it authored by people from 4 continents or 4 planets, watever, it doesn't matter for this anonymous annoyer who wants to ruffle you...lol
no no. Uma's paper is rubbish rubbish....
and in the previous video, the calf was attacked; the felines thought it was an easy prey; the alligator wouldn't miss a chance; yet the meek moo survived.
Now, Uma would survive the ruthless beast's comments !

Yes, Uma's paper was kind of rubbish....lol ;-)

Hmm, maybe not....

yeah! yeah! whatever! as i wrote before human struggle is to show the strength of the brain... so Uma is still standing ;-)
