Title: | Microarray Analyses of Arabidopsis cgl1 (complex glycan 1) Mutants and Genetic Interaction with stt3 |
Date: | 2011-05-05 |
Description: | We compare two Arabidopsis thaliana cgl1 alleles and report on genetic interaction with stt3a in double mutants. STT3a encodes a subunit of oligo-saccharyl-trans-ferase that affects efficiency of N-glycan transfer to nascent secretory proteins in the ER; cgl1 mutants lack N-acetyl-gluco-saminyl-trans-ferase-I activity and are unable to form complex N-glycans in the Golgi apparatus. In cgl1 C6, a point mutation affects the 3'-splice site of intron 14, resulting in frame shifts; and in cgl1-T, intron 11 fails to splice due to insertion of a T-DNA copy. Introgression of stt3a-2 did not restore complex glycan formation in cgl1 C6 or cgl1-T (Frank et.al.,2008). In this microarray experiment, Seeds were grown on 1/4 MS media supplemented with 0.5% sucrose and 0.8% agar in a growth chamber under long-day photoperiod (16-hr light, 8-hr darkness) at 24 ± 2°C for 10 days. Then, seedlings were transferred into soil and grown three more weeks in a growth chamber at 25 ± 2ºC under long-day photoperiod at a light intensity of 40 ¼mol m-2s-1. Then, shoots from 5 plants were pooled and total RNAs were extracted according to Chomczynski (1993). |
