Transposon Tagging of the Defective embryo and meristems Gene of Tomato

Abstract: The shoot and root apical meristems (SAMs and RAMs, respectively) of higher plants are mechanistically and structurally similar. This has led previously to the suggestion that the SAM and RAM represent modifications of a fundamentally homologous plan of organization. Despite recent interest in plant development, especially in the areas of meristem regulation, genes specifically required for the function of both the SAM and RAM have not yet been identified. Here, we report on a novel gene, Defective embryo and … Show more

“…To test the effect of introns on transgene silencing, we inserted the intron from the endogenous DEM1 gene (Keddie et al. , 1998) of Arabidopsis ( At4g33400 ) within the 5′ untranslated region (UTR) of the 35S:GFP transgene.…”

“…To test the effect of introns on transgene silencing, we inserted the intron from the endogenous DEM1 gene (Keddie et al, 1998) of Arabidopsis (At4g33400) within the 5¢ untranslated region (UTR) of the 35S:GFP transgene. Remarkably, the percentage of silenced T 1 plants was reduced from 85% without the intron to 36% with the DEM1 intron (Figure 2c,d).…”

“…In addition, they reported that the variation in Cbf genes, which do not carry any introns, is widespread in the Triticeae [ 26 ]. This gene family is regulated by two wheat specific Ice genes under cold conditions [ 27 , 28 ]. Both Ice genes have four exons [ 29 , 30 ].…”

“…In Arabidopsis , as a paradigm for dicot embryonic development, cotyledons are specified from two lateral domains at the apical end of the embryo proper at the heart stage, showing bilateral symmetry [ 2 ]. Several studies have reported cotyledon mutants in Arabidopsis [ 3 7 ], Antirrhinum [ 8 ], tomato [ 9 11 ], and other plants [ 12 ]. These mutants have been used to identify a number of orthologous gene hierarchies that are involved in cotyledon development [ 13 ].…”
