Glabrous rice exhibits glabrous leaves and hulls because neither of these structures have trichomes on their surfaces.Glabrous rice varieties have become an important germplasm resource in the rice industry because they have considerable packaging efficiency and can reduce skin itching and dust during harvesting,drying,and packing(Shim et al.,2012;Zhang et al.,2012).Trichomes are ubiquitous in land plants and they originate from the expansion of the epidermal cell and then develop through growth,differentiation,or cell division to produce hair-like tissues that extend from epidermal surfaces Glabrous rice exhibits glabrous leaves and hulls because neither of these structures have trichomes on their surfaces. Glabrous rice varieties have become an important germplasm resource in the rice industry because they have comparable packaging efficiency and can reduce skin itching and dust during harvesting, drying, and packing (Shim et al., 2012; Zhang et al., 2012). Trichomes are ubiquitous in land plants and they originate from the expansion of the epidermal cell and then develop through growth, differentiation, or cell division to produce hair-like tissues that extend from epidermal surfaces
