“…The use of natural genetic variation in photosynthesis within species can be an effective strategy for crop improvement (Flood et al , 2011). Wide variations in P n among rice cultivars have been shown in a number of studies (Murata, 1961; Takano and Tsunoda, 1971; Cook and Evans, 1983; Yeo et al , 1994; Osada, 1995; Xu et al , 1997; Masumoto et al , 2004; Kanemura et al , 2007; Jahn et al , 2011). However, most of the natural genetic resources have yet to be tapped.…”

Increases in rates of individual leaf photosynthesis (P n) are critical for future increases of rice yields. A previous study, using introgression lines derived from a cross between indica cultivar Habataki, with one of the highest recorded values of P n, and the Japanese elite cultivar Koshihikari, identified four QTLs (qCAR4, qCAR5, qCAR8, and qCAR11) that affect P n. The present study examined the combined effect of qCAR4 and qCAR8 on P n in the genetic background of Koshihikari. The pyramided near-isogenic line NIL(qCAR4+qCAR8) showed higher P n than both NIL(qCAR4) and NIL(qCAR8), equivalent to that of Habataki despite being due to only two out of the four QTLs. The high P n of NIL(qCAR4+qCAR8) may be attributable to the high leaf nitrogen content, which may have been inherited from NIL(qCAR4), to the large hydraulic conductance due to the large root surface area from NIL(qCAR4), and to the high hydraulic conductivity from NIL(qCAR8). It might be also attributable to high mesophyll conductance, which may have been inherited from NIL(qCAR4). The induction of mesophyll conductance and the high leaf nitrogen content and high hydraulic conductivity could not be explained in isolation from the Koshihikari background. These results suggest that QTL pyramiding is a useful approach in rice breeding aimed at increasing P n.

“…Phenotypic variation for carbon assimilation or ''A'' has been investigated on small sets of germplasm of Arabidopsis (Christman et al 2008), rice (Hubbart et al 2007;Kanemura et al 2007), cotton (Pettigrew 2004;Pettigrew and Gerik 2007;Zeng et al 2012), soybean (Gilbert et al 2011), sunflower (Herve et al 2001) and wheat (Sadras et al 2012). In sorghum, a strong correlation between A and stomatal conductance (g s ) was identified on a set of 30 sorghum lines under different water regimes (Kidambi et al 1990).…”

Carbon assimilation is the fundamental basis of crop productivity, but this important and complex trait has not been genetically characterized and directly exploited at the commercial level to improve yield. Therefore, there is a critical need to determine natural genetic variation in carbon assimilation, to advance our knowledge of the genetic mechanisms controlling this trait and, on that basis, to develop germplasm with superior photosynthetic capacity. Sorghum is the most productive annual species for biofuel production in which leaf photosynthetic capacity has been associated with biomass yield. In this study, a set of 82 sorghum accessions was genetically characterized and phenotypically evaluated for carbon assimilation (A), stomatal conductance (g s ), transpiration rate (T), efficiency of energy capture by open PSII reaction centers (Fv 0 /Fm 0 ), effective quantum yield (U PSII ) and photochemical quenching (qP). Phenotypic variation was observed for all traits, with A ranging from 11.6 to 42.5 lmol CO 2 m -2 s -1 . The highest positive correlations were between A and U PSII (r = 0.71), g s and T (r = 0.89) and U PSII and qP (r = 0.91). The highest negative correlations were between g s and A/g s (r = -0.82), T and A/g s (r = -0.79), T and A/T (r = -0.79) and A/g s and A/T (r = -0.78). Population structure and cluster analysis clearly differentiated three subpopulations among this set of accessions with significantly different values for A, g s and Fv 0 /Fm 0 . This study demonstrates that this diverse set of sorghum accessions could be utilized to identify genes/markers associated with variation in leaf photosynthetic rate and could be exploited in breeding programs to develop germplasm with superior carbon assimilation capacity.

“…LNC is closely correlated with leaf Rubisco content, and one of the most important parameters on photosynthesis (Evans, 1989;Hirasawa et al, 2010;Makino et al, 1992). There are significant varietal differences in LNC in rice cultivars even under the same N fertilizer treatment (Hirasawa et al, 2010;Kanemura et al, 2007). LNC of Shennong265 was higher than that of Nipponbare or Takanari at the same rate of N application (Table 2, 4).…”

Increasing the yield of rice per unit area is important because of the demand from the growing human population in Asia. A group of varieties called erect panicle-type rice (EP) achieves very high yields under conditions of high nitrogen availability. Little is known, however, regarding the leaf photosynthetic capacity of EP, which may be one of the physiological causes of high yield. We analyzed the factors contributing to leaf photosynthetic rate (P n ) and leaf mesophyll anatomy of Nipponbare, Takanari, and Shennong265 (a EP type rice cultivar) varieties subjected to different nitrogen treatments. In the field experiment, P n of Shennong265 was 33.8 μmol m −2 s −1 in the high-N treatment, and was higher than that of the other two cultivars because of its high leaf nitrogen content (LNC) and a large number of mesophyll cells between the small vascular bundles per unit length. In Takanari, the relatively high value of P n (31.5 μmol m −2 s ) in the high-N treatment. In the pot experiment, the ratio of P n /C i to LNC, which may reflect mesophyll conductance (g m ), was 20-30% higher in Nipponbare than in Takanari or Shennong265 in the high N availability treatment. The photosynthetic performance of Shennong265 might be improved by introducing the greater ratio of P n /C i to LNC found in Nipponbare and greater stomatal conductance found in Takanari.
