Regarding leaf sheath color, 20 and 30 accessions exhibited purple and green, respectively.
Taichung Sen 17 (TCS17) with green leaf sheath was utilized to isolate a gene conferring leaf sheath color by positional cloning.
Taichung Sen 17 (TCS17) with green leaf sheath (GSH) was utilized to isolate a gene conferring leaf sheath color.
The F2 population of TNG72 ×TCS17 was used to identify the gene conferring leaf sheath color by positional cloning.
A panel of 50 accessions obtained from the National Plant Genetic Resources Center (NPGRC), Taiwan and The Oryza Map Alignment Project (OMAP) were used to reveal DNA sequence diversity of the gene conferring leaf sheath color.
One or two major QTLs were suggested to confer leaf sheath color, and two QTLs mapped on chromosomes 1 and 6 could explain more than 50%% of phenotypic variation (Hadagal et al. 1980; Yue et al. 2006).
OsC1, conferring leaf sheath color, was isolated from the F2 population of TNG72 × TCS17 by positional cloning (Fig. 2), differing from PSH1 (t) but the same as a locus identified from the somaclonal line Z418 (Wang et al. 2009; Gao et al. 2011).
b1 is a gene in the anthocyanin synthesis pathway that has been identified as a QTL for sheath color differences among mexicana and parviglumis (Lauter et al. 2004).
For example, the characters seed shattering, awn presence, red/brown pericarp color, purple leaf sheath color, and seed dormancy were positively or negatively correlated with several of the eight crop mimic traits in the large F2 population (Table 2).
In this study, 33 children diagnosed with P. falciparum underwent targeted ultrasound examinations of optic nerve sheath diameter, color transcranial Doppler insonation of the cerebral vasculature, cardiac ultrasound and abdominal ultrasound to evaluate spleen size.
