• Genotypic Variation in Root Growth Angle in Rice (Oryza sativa L.) and its Association with Deep Root Development in Upland Fields with Different Water Regimes (2006, unknown): “Among environmental effects, the effects of water regime on deep root development of rice grown in pots is well understood (Asch et al. 2004; Azhiri-Sigari et al. 2000; Bañoc et al. 2000; Price et al. 2002).”

• Root traits contributing to plant productivity under drought (2013, background): “These include in rice: increased root length (Price et al., 2002; MacMillan et al., 2006; Courtois et al., 2009), root biomass (Courtois et al., 2003), and root number (Zheng et al., 2000, 2003; Courtois et al., 2009); in wheat: increased total root biomass, length and number of roots (Sharma et…”
• Improvement of rice drought tolerance through backcross breeding: Evaluation of donors and selection in drought nurseries (2006, background): “…to understand the genetic basis of putative drought-adaptive traits in rice (Babu et al., 2003; Courtois et al., 2000; Price and Courtois, 1999; Price et al., 2002a,c; Robin et al., 2003), but it has been difficult to identify genetic segments with clear and repeatable effects on yield under…”
• Characterization of the effect of a QTL for drought resistance in rice, qtl12.1, over a range of environments in the Philippines and eastern India (2009, background): “…of QTL effects across different populations (QTL 9 genetic background interaction) and across environments (QTL 9 environment interaction) are two factors limiting the use of QTL for MAS by plant breeders (Price et al. 2002; Courtois et al. 2003; Lafitte et al. 2004a; Bernier et al. 2008).”
• Morphological and architectural development of root systems in sorghum and maize (2010, unknown): “Plant size and root architecture thus represent two contrasting drought adaptation mechanisms, and the results for sorghum imply that these mechanisms could potentially operate independently, as has been observed in rice (Price et al. 2002).”
• Influence of the soil physical environment on rice (Oryza sativa L.) response to drought stress and its implications for drought research (2011, methodology): “QTLs associated with root growth traits were identified in the Bala/Azucena population under controlled conditions in hydroponics (Price and Tomas, 1997), a wax layer (Price et al., 2000), and a soil-filled rhizotron (Price et al., 2002c).”
• Locating QTLs controlling constitutive root traits in the rice population IAC 165 × Co39 (2003, background): “The field of adaptive responses was explored by Hemamalini et al. (2000), Zhang et al. (2001b) and Price et al. (2002) who looked at the expression of root traits in situations of water deficit.”
• Phenotypic and genotypic analysis of drought-resistance traits for development of rice cultivars adapted to rainfed environments (2008, background): “Other secondary traits such as leaf rolling (Champoux et al., 1995; Babu et al., 2003), leaf drying (Price et al., 2002b; Babu et al., 2003), and canopy temperature (Yue et al., 2005) under drought stress have been mapped in this region (Table 3).”
• Pot size matters: a meta-analysis of the effects of rooting volume on plant growth. (2012, background): “Although the vertical root distribution is relatively easily measured (Price et al. 2002; Suriyagoda et al. 2010), analysis of the horizontal distributions is more complicated.”
• Root biology and genetic improvement for drought avoidance in rice (2011, background): “…Ekanayake et al., 1985a), deep root to shoot ratio (Yoshida and Hasegawa, 1982), root number (ArmentaSoto et al., 1983), root growth plasticity (O’Toole, 1982; Ingram et al., 1994; Price et al., 2002), and root penetration ability (Babu et al., 2001; Clark et al., 2008, 2000; Ali et al., 2000).”
• Genetic engineering and breeding of drought-resistant crops. (2014, background): “(87) corresponds to a locus affecting diverse root traits reported by MacMillan et al.”
• Fractal analysis on root systems of rice plants in response to drought stress (2009, background): “Root growth and development is considered very important for rice to adapt to soil water deficit stress (O’Toole, 1982; Fukai and Copper, 1995; Price and Courtois, 1999; Price et al., 2002; Wade et al., 1999; 2000; Kato et al., 2006; Wang and Yamauchi, 2006).”
