WormMine: ExpressionPattern Expr8121

• Pattern: In complex arrays, expression was occasionally observed along the entire length the adult gonad in a "honeycomb" pattern characteristic of gonad expression. This expression was faint and variable (not observed in all animals) and tended to dissipate as the complex array lines were maintained for more than three generations. This pattern could reflect expression in the germ line, the somatic sheath cells, or both. Male gonads, which are devoid of sheath cells, also showed faint and variable expression along their lengths, suggesting that expression might be in the germ line. However, sheath cell expression cannot be excluded from these experiments.
