RT   "Characterization of a pollen-specific cDNA clone from Nicotiana tabacum
RT   expressed during microgametogenesis and germination.";
RL   Plant Mol. Biol. 18:1101-1111(1992).
CC   -!- FUNCTION: Probable oxidoreductase that may be involved in pollen tube
CC       growth. {ECO:0000269|PubMed:1600146}.
CC   -!- SUBCELLULAR LOCATION: Secreted, extracellular space {ECO:0000305}.
CC   -!- TISSUE SPECIFICITY: Pollen. {ECO:0000269|PubMed:1600146}.
CC   -!- DEVELOPMENTAL STAGE: Appears after the first haploid mitosis and are
CC       expressed during microgametogenesis, germination and tube growth.
CC       {ECO:0000269|PubMed:1600146}.
CC   -!- INDUCTION: Expression regulated by the haploid gametophyte itself.
CC       {ECO:0000269|PubMed:1600146}.
CC   -!- SIMILARITY: Belongs to the multicopper oxidase family. {ECO:0000305}.
