RSA in monocots
Monocots comprises of fibrous roots and have more complex root structure than dicots. Fibrous roots in monocots generally refers to the nodal roots along with many finer roots (Maqbool et al., 2022). Generally, in monocots the formation of shoot-borne roots a.k.a nodal roots is necessary to increase the vasculature system as monocots lack secondary thickening in roots and thereby lead to increased uptake of nutrients and water. In wheat, two types of roots are present; nodal roots which originates from basal portion of tillers and seminal roots which originates from embryonic seed part (Manske et al 2002;Wasaya et al., 2018) while only embryonic primary roots are present in rice. LR are developed from cells of pericycle, however it has been reported that in monocots such as rice and maize, pericycle cells of xylem poles are not competent to produce LR and thereby initiation of those occurs in endodermal and pericycle cells opposite phloem poles (Yu et al., 2016).
