Gene Details:

• Gene ID:
• Gene Symbol: BoPMEI1
• Gene Name: pectin methylesterase inhibitor
• Genome:
• Species: Brassica oleracea

Functional Descriptions:

• BoPMEI1, a pollen-specific pectin methylesterase inhibitor, has an essential role in pollen tube growth.
• Heterologously expressed BoPMEI1 showed PMEI activity. RT-PCR studies of different tissues and promoter-GUS fusions confirmed that BoPMEI1 was specifically expressed in mature pollen grains and pollen tubes.
• Based on in vivo transient assays, we found that BoPMEI1 appears to be largely localized to the plasma membrane.
• Transgenic Arabidopsis plants expressing antisense BoPMEI1 under the control of the CaMV 35S promoter suppressed the expression of the orthologous gene At1g10770, which led to partial male sterility and decreased seed set by inhibition of pollen tube growth. Our study demonstrates the involvement of BoPMEI1 in pollen tube growth.
