On the transcriptional level, andropetals may have arisen through a repression of C gene expression in an outer whorl of stamens whereas bractopetals may have evolved by an expansion of B gene expression into pre-existing sterile organs [29].
Relentlessly mocked by everyone from John Betjeman to Hyacinth Bucket, only that lonely Shepperton radical JG Ballard gave them the time of day, and even then he couldn't resist painting them as harsh, sterile worlds existing on the precipice of a horrifying near future, chock-a-block with perverts and terrorists.
It will build a new aseptic sterile plant where existing and new biopharmaceutical products will be made.
Expression of the barnase gene in ornamental plants under control of the anther-specific PsEND1 promoter may be used to create efficient male sterile versions of existing popular cultivars without adversely affecting their respective phenotypes.
Expression of the barnase gene under control of the anther-specific PsEND1 promoter [ 38, 39, 41, 42] may be used to efficiently create male sterile versions of existing pelargonium cultivars without adversely affecting the respective phenotypes.
General knockdown of the gene caused great reduction in larval viability, whereas existing nopo mutations are viable and sterile (Merkle et al. 2009).
About 37% of respondents reported that they mainly procured sterile needles and syringes from existing programs (needle syringe exchange programs -NSEP) operated through drop-in-centres (DIC) or through outreach workers.
Instead we are subjected to sterile arguments about who might manage the existing system best.
They called on politicians to raise their sights beyond "sterile arguments about who might manage the existing system best".
Although no E. coli were isolated from the 2 feed mill samples, other Enterobacteriaceae grew on the agar plates, which could have overgrown existing E. coli strains, if any, demonstrating that the feed was not sterile.
When sterile, one voucher per population was taken; this was compared to already existing collections in Noumea Herbarium (NOU) from the same location and referred to that species if similar.
