Studies on the lateral root formation in rice plant : (II) Lateral root formation under several abnormal conditions

Characterization of root traits for phosphorus deficiency tolerance using chromosome segment substitution lines

“…The genotypes SL417 and SL438 not only had thick nodal roots, but also had longer finer roots. Several studies have examined the interaction of nodal root and lateral root formation in rice (Kawata andShibayama 1966, Matano andNagai 1966); however, the relationship between nodal root and lateral root formation is not fully understood. As for the interaction between lateral root and RCA in nodal root, Lynch (2010, 2011) suggested that RCA in maize affected increased lateral root formation by reduction root respiration, allowing carbon to be used for greater soil exploration.…”

Effect of soil microorganisms on the growth of roots in rice seedlings

“…STREET (24) reported that apical meristems of primary roots released some substances inhibiting an initiation and growth of secondary roots, which especially occur in the immediate vicinity of root apices. On the contrary, the inhibition of the meristematic activity of primary roots was reported to enhance the generation of secondary roots (16,17,24). In the present experiment, the suppression of the meristematic activity of primary roots by microorganisms seemed to stimulate the development of secondary roots.…”

Effects of soil microorganisms on the growth and on the nitrogen and phosphorus absorption by rice seedlings

“…The formation of lateral roots is known to be stimulated when the apical meristem of the main root is inhibited (19,(24)(25)(26). Surfaces of lateral roots and root hairs occupy almost all the surface area of the roots (27) and these parts of the roots have a high ability in absorbing the nutrients (28).…”
