The Asian ladybird beetle, Harmonia axyridis shows polymorphism in elytra color patterns. However, it is uncertain whether these color patterns are regulated by genetic factors. This investigation used amplified fragment length polymorphism (AFLP) analysis to determine any genetic causes of the variability of color patterns. Using four individuals of each group, AFLP analysis produced 37 polymorphic bands. Among several polymorphic bands, six AFLP markers were associated with elytra color patterns after further analysis using six additional individuals of each group. These polymorphic sites were sequenced but did not match DNA sequence data deposited in GenBank. Based on the color-associated AFLP markers, SCAR primers were designed for PCR amplification of genomic DNA. These primers (SCAR 12 and SCAR 44) were used to analyze color-associated loci and/or alleles of H. axyridis DNA. SCAR 12 primers designed from a Spectabilis type-specific fragment (AFLP 12) amplified a specific band of 530 bp in four Spectabilis individuals, but not in the insects with other color patterns. 相似文献

Panicum meyerianum Nees is a wild relative of Panicum maximum Jacq. (guinea grass), which is an important warm-season forage grass and biomass crop. We investigated the conditions that
maximized the transformation efficiency of P. meyerianum by Agrobacterium infection by monitoring the expression of the β-glucuronidase (GUS) gene. The highest activities of GUS in calli were achieved
by the co-cultivation of plants with Agrobacterium at 28°C for 6 days. We transferred the ddsA gene, which encodes decaprenyl diphosphate synthase and is required for coenzyme Q10 (CoQ10) synthesis, into P. meyerianum by using our optimized co-cultivation procedure for transformation. We confirmed by PCR and DNA gel blot hybridization that
all hygromycin-resistant plants retained stable insertion of the hpt and ddsA genes. We also demonstrated strong expression of S14:DdsA protein in the leaves of transgenic P. meyerianum. Furthermore, we showed that transgenic P. meyerianum produced CoQ10 at levels 11–20 times higher than that of non-transformants. By comparison, the CoQ9 level in transgenic plants
was dramatically reduced. This is the first report of efficient Agrobacterium-mediated transfer of a foreign gene into the warm-season grass P. meyerianum. 相似文献
