Genomic Clones Complementing hll.
Three cosmid subclones (cT24L7-9, cT24L7-103, and cT24L7-143) of BAC T24L7 complemented the hll-1 mutant. A total of one (cT24L7-103) plus one (cT24L7-9) plus three (cT24L7-143) transgenic plants were homozygous for hll-1 but had a wild-type phenotype. The cosmids had three genes in common: A, B, and a tRNA gene. A subclone of cT24L7-143 containing gene B and the tRNA (pDS08) also complemented the mutant (one plant).
