lateral root


Also found in: Encyclopedia, Wikipedia.

lateral root

or

secondary root

the branches that develop from deep inside the plant root (i.e. are ENDOGENOUS) where cells of the PERICYCLE become meristematic (see MERISTEM and produce a growing point which differentiates into mature tissues. Such branching occurs behind the root hair zone and is initiated by AUXIN.

However, shading reduced both main root length at 24 and 27DAE, lateral root length and total length at 21, 24 and 27DAE (Table 1, Figure 3).
In an in vitro study repairing lateral root perforations, methylene blue has been used to compare the sealing ability of MTA, to amalgam, and intermediate restorative material and MTA showed the least leakage and least over filling 12.
In three arms of those with an origin of the MCN from the lateral cord of the brachial plexus, the MCN arose at the level of the latissimus dorsi tendon, accompanied by a lateral root of the median nerve with mean length of 45.6 mm (Fig.
Initial evaluations of MTA indicated that it had good performance in sealing lateral root perforations, and in root-end fillings, owing to its ability to improve the mineralization process.
Development of lateral root was also affected by the application of different treatments.
The use of gibberellin also triggered reductions in the root fresh mass of treated seedlings when compared to control (Figure 3), probably by inhibiting the initiation of lateral root primordia (Gou et al., 2010) and/or by unbalancing the synthesis or transport of endogenous hormones (Nikolic et al., 2010).
On radiographical examination, OPG revealed a large, well-defined periapical radiolucency arising from the lateral root surface of an impacted permanent left mandibular first molar and second premolar.
This article presents a non-surgical management of a case with chronic lateral root perforation with an open apex.
The median nerve is formed by the combination of the lateral root from the lateral cord and medial root from the medial cord of the brachial plexuses.
A new index was proposed in this study and was calculated using the ratio of [Log.sub.10]([a.sub.PR]) to [Log.sub.10](u) to verify the relative positions of branching in the root systems relative to the primary root because the indices mentioned above do not indicate whether the herringbone pattern forms along the primary root or a lateral root (Figure 1).
