| thermotolerance of leaf discs from four isoprene-emitting species is not enhanced by exposure to exogenous isoprene | the effects of exogenously supplied isoprene on chlorophyll fluorescence characteristics were examined in leaf discs of four isoprene-emitting plant species, kudzu (pueraria lobata [willd.] ohwi.), velvet bean (mucuna sp.), quaking aspen (populus tremuloides michx.), and pussy willow (salix discolor muhl). isoprene, supplied to the leaves at either 18 &mgr;l l-1 in compressed air or 21 &mgr;l l-1 in n2, had no effect on the temperature at which minimal fluorescence exhibited an upward inflection ... | 1999 | 10398717 |
| constitutive expression of the sap1 gene from willow (salix discolor) causes early flowering in arabidopsis thaliana. | sap1-1 and sap1-2 were isolated from the male reproductive buds of willow (salix discolor, clone s365). sap1-1 differs from sap1-2 based on a few nucleotide substitutions, but the sizes of their full-length cdnas are identical. the deduced amino acid sequences of sap1-1 and sap1-2 were 98% similar and contain the same c-terminal amino acid motif "gyga" like that of ptap1-2 from populus trichocarpa. the expression patterns of sap1 in various parts of the male reproductive buds of s. discolor impl ... | 2006 | 16228224 |
