TI is a function of homologous DNA length. TI frequency vs. homologous
DNA length is plotted for three different data sets. ▴, Five
published gene knockouts in M. grisea strain Guy 11. MA,
MAC1 (36); P, PMK1 (23); A, ABC1 (37); M, MPG1 (21); N = NUT1
(38). Published TI frequencies are 16%, 11%, 21%, 3%, and 22%,
respectively. □, MAC1 TAGKO cosmid subjected to
KpnI, EcoRI and SpeI,
restriction digestion yielding, three MAC1 constructs with the same
insertion but different homologous DNA lengths of 5.5 kb, 13.5 kb, and
20.2 kb, respectively. ○, Ten different TAGKO constructs
created by IVT into a cosmid library pool.
