Evolution of genetic mechanisms controlling petal development
Article Abstract:
The genetic mechanisms controlling floral development in angiosperm species outside the higher eudicots has been assessed in order to determine the extent of conservation of the ABC model. This model states that sepal identity is established by the functions of A genes alone, with petal identity being established by A and B, stamen identity by B and C and carpel identity only by C function. This research has reconsidered the view that the ABC programme as defined in the higher eudicots is strictly conserved across all the angiosperms. In the Ranunculids, other genes could have been recruited to perform the role of specifying petal identity.

A plant regulator controlling development of symbiotic root nodules
Article Abstract:
Research designed to identify the regulatory elements that function early in nodule induction has involved characterizing a transposon-tagged Lotus japonicus mutant, nin, arrested at the stage of bacterial recognition. It has been established that nin is needed for the formation of infection threads and the initiation of primordia. The phenotype of the nin mutants shows that Nin is involved in the inception of root nodules. The characteristics of NIN the protein indicate that it acts as a transcriptional regulator of genes needed for nodule development.

A plant cold-induced uncoupling protein
Article Abstract:
Genetic research has established a gene which encodes the plant uncoupling protein StUCP. Evidence suggests that StUCP is used by plants for temporary control. Its expression has been achieved using the yeast Saccharomyces cerevisiae. A 1.5 kilobase transcript of StUCP has been located in potato leaves and tubers. It is also expressed in stolens. StUCP contains some of the same genetic sequences found in mitochondrial transporters.
