    Also known as
    ATCHITIV; ATEP3; CHITINASE CLASS IV; CHIV; homolog of carrot EP3-3 chitinase; T14E10.4
    Summary
    encodes an EP3 chitinase that is expressed during somatic embryogenesis in 'nursing' cells surrounding the embryos but not in embryos themselves. The gene is also expressed in mature pollen and growing pollen tubes until they enter the receptive synergid, but not in endosperm and integuments as in carrot. Post-embryonically, expression is found in hydathodes, stipules, root epidermis and emerging root hairs.
