Color Gene

The enzyme flavonoid 3′,5′-hydroxylase (F3′5′H) plays an important role in producing anthocyanin pigments in soybean. Loss of function of the W1 locus encoding F3′5′H always produces white flowers. However, few color variations have been reported in wild soybean. In the present study, we isolated a new color variant of wild soybean accession (IT261811) with pinkish-white flowers. We found that the flower’s pinkish-white color is caused by w1-s3, a single recessive allele of W1. The SNP detected in the mutant caused amino acid substitution (A304S) in a highly conserved SRS4 domain of F3′5′H proteins. On the basis of the results of the protein variation effect analyzer (PROVEAN) tool, we suggest that this mutation may lead to hypofunctional F3′5′H activity rather than non-functional activity, which thereby results in its pinkish-white color.

Maize Transposable Element

We have assayed the transposition activity of the maize transposable element Ac in transgenic tomato plants that had a single copy of Ac. We found that Ac elements were in either a high or low activity state and that an Ac insertion could cycle from low to high activity within a generation. The different transposition activities were not simply due to the chromosomal position of the element, because the same Ac insertion had different levels of activity in sibling plants. Transposition activity was measured by two methods, one genetic and one physical; both assays gave similar results for each plant studied. Notably, plants with active Ac elements had progeny with amplified Ac copy number, while no amplification was detected in lines containing Ac in a low activity state. Analysis of lines with amplified elements revealed that the elements could be either clustered or dispersed. Our results were consistent with amplification being the result of transposition.Key words: Ae, transposable element, amplification, transposition.
