Transgenic Larch ( Larix Species)

Larches are deciduous needle-leaf gymnosperms family Pinaceae in the genus Larix which is composed of ten species, with numerous varieties and hybrids. Larches are well adapted to regions where the climate is typically cold with a short growing season: some larch species are native to the lowlands of boreal zones (Larix laricina in Northern America, L. russica and L. gmelinii in Siberia), whereas others are localized at the subalpine or montane level in more temperate areas (L. decidua in Europe, L. occidentalis and L. lyalli in the Rocky Mountains, L. kaempferi in Japan, L. griffithiana in Himalayas, L. potaninii and L. mastersiana in China; Schmidt 1992).
