(a.) Of or pertaining to petiole, or proceeding from it; as, a petiolar tendril; growing or supported upon a petiole; as, a petiolar gland; a petiolar bud.
Example Sentences:
(1) The organization and expression of the mitochondrial (mt) genome of fertile, male-sterile and restored lines of Helianthus annuus and of H. petiolaris were compared to identify alterations which might lead to cytoplasmic male sterility (CMS).
(2) As the expression of the 16 kDa polypeptide seems to be linked to the interspecific cross between H. petiolaris and H. annuus it may play a role in CMS.
(3) texanus, known as ANT1, contained a unique mitochondrial DNA fragment, which is distinguishable from the fertile and sterile Petiolaris genotypes and from all investigated CMS genotypes.
(4) Comparing the mitochondrial in organello translation products we observed a unique 16 kDa protein, which is expressed in male-sterile lines carrying the H. petiolaris cytoplasm but is not detectable in fertile lines with H. annuus cytoplasm.
(5) Using the atpA probe, 5 from the 6 investigated CMS genotypes showed identical hybridization patterns to the Petiolaris CMS line, which is used in all commercial sunflower hybrids.
(6) The 16 kDa protein can also be observed in restored lines but not in H. petiolaris.
(7) Male fertility restoration and male sterility maintenance of the ANT1 line are different from the Petiolaris CMS system, which is a confirmation that a novel CMS genotype in sunflower has been identified.
