Seed-specific expression of a lysine rich protein sb401 gene significantly increases both lysine and total protein content in maize seeds
The sb401 gene from potato (Solanum berthaultii) encoding a pollen-specific protein with high lysine content was successfully integrated into the genome of maize plants and its expression was correlated with incr...

Effects of in vitrorooting environments and irradiance on growth and photosynthesis of strawberry plantlets during acclimatization
Strawberry (Fragaria ananassaDuch. cv. Fengxiang) plantlets were cultured under two in vitroenvironments for rooting, and then acclimatized under two ex vitroirradiance conditions. At the end of rooting stage pla...

Ectopic expression of a maize pollen specific gene, zm401, results in aberrant anther development in tobacco
Our previous study shows that the maize zm401 cDNA is specifically expressed in maize pollens. This evidence suggests that zm401 likely functions in pollen growth and/or development. To confirm its possible invol...

Controlling Transgene Escape in GM Cree** Bentgrass
Trait improvement of turfgrass through genetic engineering is important to the turfgrass industry and the environment. However, the possible transgene escape to wild and non-transformed species raises ecologic...

Regeneration of Syngonium podophyllum ‘Variegatum’ through direct somatic embryogenesis
A simple and effective method of regenerating Syngonium podophyllum ‘Variegatum’ via direct somatic embryogenesis has been established. Leaf and petiole explants were cultured on Murashige and Skoog (MS) medium s...

Effect of mouse calcineurin on induction and growth of rice callus transformed by the calcineurin gene
Calcineurin is a Ca2+/calmodulin dependent serine/threonine protein phosphatase, and has multiple functions in animal cells. In this work, mouse calcineurin was introduced into wild-type rice and the expression o...

Particle-Bombardment-Mediated Co-Transformation of Maize with a Lysine Rich Protein Gene (sb401) from potato
Little work has been reported on genetic transformation with maize inbred lines, especially elite inbred lines used in breeding. In this work, 7 self-pollinated inbred lines and 4 hybrid lines have been screen...

Induction, development and maturation of somatic embryos in Bunge’s pine (Pinus bungeana Zucc. ex Endl.)
Embryogenic tissue was induced from develo** immature zygotic embryos in Bunge’s pine (Pinus bungeana Zucc. ex Endl.). Induction rate reached 84.4% with our best treatment. Zygotic embryos were dissected from m...

Co-suppression of Si401, a maize pollen specific Zm401 homologous gene, results in aberrant anther development in foxtail millet
We previously reported that the maize pollen-specific gene Zm401 functions in anther development. In this study, a Zm401’s ortholog Si401 was amplified and cloned from foxtail millet (Setaria italica). Zm401 and

Fine map** of open-bud duplicate genes in homoelogous chromosomes of tetraploid cotton
The open-bud mutant plant has a flower bud that is open at its tip due to the shortening of the corollas, resulting in exposure of the stigma and upper anthers. This mutant plant is potentially useful as a par...
