Single HoSEPl transgenic plants converted their leaves to petal-like in vitro, and the leaves of weak phenotypes produce abnormal calli, and further bud differentiation more difficult, such a transformation also confirmed by RT-PCR detection of FBP1 expression, a Petunia gene specific expression to corolla and anthers Petal-like structures, rod-like structures (probable anthers ), ovary-like structures and buds can produced directly from the transgenic calli on bud differentiation medium (BDM).
Two cultivars had no stamens in the mature flowers and the third had petaloid structures in place of the stamens.
Leaf protoplasts from broccoli with the petaloid B.
These four plants and their progeny all showed the petaloid B.
Other hybrid plants were incompletely restored as they exhibited petaloid structures on the anther-bearing pollen-producing stamens.
MtDNA variation revealed nine RFLP patterns, which could be categorised according to the sex phenotype of the plants as MS1 (brown-anther type), MS2 (petaloid flower type) and MS3 (more yellow anthers than MS1).
Especially, the triblock copolymer can form a multi-layer, tri-dimensional fibrous network and a petaline structure from the mono-layer fibrous network with the increase of its concentration in ethanol.
A comparison with the floral configurations of the Phytolaccaceae and Molluginaceae indicates that the outer petaline whorl of the Caryophyllaceae corresponds positionally to the alternisepalous stamens of somePhytolacca, such asP.
In other bloodwood eucalypt species all the primordia in the corolline whorl become continuous at some stage in development, resulting in an operculum that is anatomically unresolvable into its original petaline parts.
The absence of compound petaline primordia in Arillastrum, Allosyncarpia, Stockwellia and Eucalyptopsis excludes these taxa from the eucalypt clade.
