摘要

Arabidopsis plants were transformed with a chimeric construct containing expression cassettes for GFP election marker and CaMV 35S promoter-driven?At5g35220?cDNA, via Agro bacterium-mediated method. Two transformants produced?pigmentation deficient phenotype. Analysis revealed the decrease of chlorophyll in all etiolated plants. RT-PCR showed that, total?At5g35220?mRNA levels were greatly inhibited in co-suppression lines.?PORA?and?PORB?mRNA expression were influenced also in the mutants. It is found that, the?At5g35220?gene is responsive to both inhibitor and some?hormone?with regard to MVP/MEP pathway in our study.
