Basic mutant information
Mutant name	deltandhF/ndhF-deficient tobacco
Mutant/Transgenic	mutant
Ecotype	Nicotiana tabacum, cv. Petit Havana
Mutagenesis type
(Semi-)Dominant/Recessive	recessive
Description	The ndhF transgenic tobacco was obtained from Nicotiana tabacum, cv. Petit Havana (wt) by inactivating the plastid ndhF gene by insertion of a cassette containing the spectinomycin resistance gene aadA. transgenic tobacco (ndhF), with the plastid ndhF gene knocked-out, shows low levels of the plastid Ndh complex, homologous to mitochondrial complex I, and more than a 30-day-delay in leaf senescence with respect to wt.
