Example Input:  The power function Tf = f ( Pc ) theoretically derived was experimentally confirmed by concomitant Pp and Pc measurements on intact leaflets of the liana Tetrastigma voinierianum under greenhouse conditions .
Example Output: Tetrastigma voinierianum

Example Input:  Experiments were performed on two specimens of the liana Tetrastigma voinierianum , growing in the c .
Example Output: Tetrastigma voinierianum

Example Input:  However , the lack of crossed recognition of cox2 promoters in wheat and potato is not a general situation since the A . thaliana cox2 gene is expressed and spliced when introduced into maize mitochondria , indicating that the Arabidopsis gene shares some signals with maize cox2 promoter that are sufficient for transcription ( 18 ) .
Example Output:
A . thaliana
