General Information

General Information Comment Organism
malfunction after silencing NtHXK1 using RNAi plants show stunted growth and leaf chlorosis Nicotiana tabacum
malfunction overexpression of NtHXK1 results in elevated glucose phosphorylation activity in leaf extracts or chloroplasts. NtHXK1 is able to complement the glucose-insensitive Arabidopsis mutant gin2-1 suggesting that NtHXK1 can take over glucose sensing functions Nicotiana tabacum
