A comparative ultrastructural study of pollen development in Arabidopsis thaliana ecotype Columbia and male-sterile mutant apt1-3.

Protoplasma - 1 Feb 2002

Zhang Chenhong, Guinel Frédérique C, Moffatt Barbara A

Abstract excerpt

Adenine phosphoribosyltransferase (APT) catalyzes the conversion of adenine and cytokinin bases to the corresponding nucleotides. An Arabidopsis thaliana mutant lacking the major APT isoform, APT1, is male sterile due to defects soon after meiosis. We have now used electron microscopy to define the effects of APT1 deficiency on pollen development to determine whether the changes might be attributed to adenine or...
