Reduced height, partial suppression of primary root growth, contorted leaves, lethal. Lethal at 60 days; primary effect may be on cell division and vascular tissue differentiation. Central stele of roots is highly disorganized. In coleoptile sections: abnormal leaf initials; tracheary vessels and sieve tubes are disorganzed; mesophyll parenchyma is irregular in shape, less vacuolated and still dividing. (Gavazzi 1993). Genetic 2005 8 coordinates determined from these recombination and map data: TB-8Lc des17; see MaizeGDB ID:139771. This gene was originally curated in MaizeGDB Database and the map position was displayed on the maize bins map if feasible.
