Comments
Comment typeDescription
Developmental StageStrongly expressed in tapetal cells at the flower developmental stage 10 to middle 12, where the components of pollen coat are synthesized actively. {ECO:0000269|Ref.7}.
Disruption PhenotypeReduced pollen fertility. Pollen grain exhibit a partial formation of coat and impaired water absorption and germination capacities. {ECO:0000269|Ref.7}.
FunctionRequired for the formation of pollen coats and male fertility. {ECO:0000269|Ref.7}.
Sequence CautionSequence=AAF79815.1; Type=Erroneous gene model prediction; Note=The predicted gene At1g75900 has been split into 2 genes: At1g75900 and At1g75910.; Evidence={ECO:0000305};
SimilarityBelongs to the 'GDSL' lipolytic enzyme family. {ECO:0000305}.
Subcellular LocationSecreted, extracellular space, extracellular matrix, pollen coat {ECO:0000269|PubMed:11431566, ECO:0000269|Ref.7}. Note=Localized in small granules in the tapetal cells.
Tissue SpecificityFlower buds and pollen. {ECO:0000269|PubMed:11431566}.
