Root hairs have sometimes provided contradictory evidence for microtubule/microfibril parallelism. This tissue was re-examined using optimized conditions for the fixation, before immunofluorescence, of root hairs. In phosphate buffer, microtubules did not enter the apical tip of radish root hairs and were clearly fragmented. However, in an osmotically adjusted microtubule-stabilizing buffer, mi...

A central topic in work on ellipsis is the parallelism between missing VPs and their antecedents. There is evidence that parallelism is conditioned both syntactically and semantically. This has resulted in complex hybrid principles that regulate both syntactic structures and their interpretations (e.g., Fox 1995, 2000). We present an alternative, unified account based on parallelism of semantic...
