Four cONA clones expressed in late root nodules of Canavalia lineata were isolated by differential screening using total RNA from uninfected roots, Clb1 and uricase II cONAs as competitors and named Cnod1, Cne2, Cne3 and Clb2, respectively. Cnod1, hybridized to 1450 nt mRNA, was highly homologous to cysteine proteinase gene from rice and showed nodule-specific expression, especially in late nodules. Cne2, hybrdized to 900 nt mRNA, was moderately homologous to Expressed Sequence Tag of rice and expressed mainly in root nodules. Its expression was increased at 13 OAI and subsequently remained at the same level. Cne3, hybridized to 1700 nt and 1400 ot mRNAs, was highly homologous to tonoplast membrane intrinsic protein TRG31 gene from pea and was expressed strongly in roots and nodules, but weakly in leaves. Temporal expression pattern of Cne3 was coincided with the life cycle of root nodules. Clb2, hybridized to 800 nt mRNA, was expressed from 8 OAI, amplified at 13 DAI and remained steady thereafter.eafter. |
