New Rice Varieties with Low Levels of Easy-to-digest Protein, 'LGC-Katsu' and 'LGC-Jun'

Ultrastructure of protein bodies in mutant rice (Oryza sativa L.) with altered storage protein composition

“…LGC-Jun is a crossbred line between LGC1 and 89WPKG30-433, and shows low glutelin content, lack of 26 kDa globulin, and a high content of 13 kDa prolamin (Nishimura et al 2005). Furukawa et al (2007) observed many PB-I structures in the starchy endosperm of mutant rice, LGC1 and Tashu-kei 1001, which show low-glutelin and high-prolamin content.…”

Analysis of Storage Protein Distribution in Rice Grain of Seed-Protein Mutant Cultivars by Immunofluorescence Microscopy

“…In LGC-Katsu, 13 kDa prolamin occupies half of the total protein in rice grains in stead of the low ratio of glutelins and defi ciency of 26 kDa globulin (Nishimura et al, 2005). The low-glutelin characteristic is derived from RNA interference (Kusaba et al, 2003).…”

“…Both NM67 and NM391 were bred from Nihonmasari. The LGC-Katsu was bred from the progeny of a cross between LGC-1 and a 26-kDa-globulin-defi cient mutant bred from γ-ray irradiated Koshihikari (Nishimura et al, 2005). Both LGC-1 and LGCsoft have a low-glutelin gene Lgc1 (Iida et al, 1993a(Iida et al, , 1993b.…”

“…Seed-protein mutant cultivars of rice (Oryza sativa L.) with low ratios of digestible proteins such as glutelin (Nishimura, 2002;Uehara et al, 2002;Iida et al, 2004;Nishimura et al, 2005) are anticipated for production of dietary foods for patients with kidney disease (Mochizuki and Hara, 2000;Muromoto and Shigeta, 2007;Yamauchi et al, 2007). Moreover, they have been examined for brewing Japanese sake (Takahashi and Sakurai, 2000;Iwano et al, 2002;Furukawa et al, 2004Furukawa et al, , 2005, and are used to breed rice cultivars for sake-brewing Iida et al, 2009).…”

Effects of Temperature on the Digestible Protein Content of Grains during Ripening in a Seed-protein Mutant Rice Cultivar LGCsoft

“…In Japan, seed-protein mutant cultivars of rice (Oryza sativa L.) with low ratios of digestible proteins such as glutelin to total protein have been developed in recent years (Nishimura, 2002;Uehara et al, 2002;Iida et al, 2004;Nishimura et al, 2005). Such rice cultivars are anticipated for production of dietary foods for patients with kidney diseases (Mochizuki and Hara, 2000;Muromoto and Shigeta, 2007).…”
