Basic mutant information   
Mutant name Ataln
Mutant/Transgenic mutant
Ecotype Col-0
Mutagenesis type T-DNA
(Semi-)Dominant/Recessive recessive
Description Older leaves of the Ataln mutant exhibited early senescence, lower soluble protein and lower organic-N levels as compared to wild-type (WT) older leaves when grown with 1 mM nitrate but were comparable to WT under 5 mM nitrate.
