STOP1 induction at low Pi promotes an association between malate and Fe3+, increasing the availability of Pi and affecting the root apex
(3) all the accessory canals were found within 2 mm from root apex
Parental plants root apexes
, callus tissue, embryos in different developmental stages (globular, heart and torpedo), and root apices from 20 regenerated Solanum tuberosum cv.
4.75 produce ROS in the elongating zone of the root apex

Peroxidase activity along the main root apex
of aluminum tolerant and sensitive maize inbred lines (Abstract # 52).
It is now generally accepted that the root apex
plays a major role in Al detection and response mechanisms (Delhaize and Ryan 1995; Kochian 1995; Rengel 1996).
The degree of hematoxylin staining in root tips provides a semiquantitative measure of Al content in root tips, and is inversely proportional to both the ability of a genotype to exclude Al from the root apex
, and its Al tolerance (Polle et al., 1978).
Endodontic management of a chronic periapical abscess in a maxillary central incisor with an immature root apex
using platelet-rich fibrin: A case report.
Electronic apex locator (EAL) was first introduced by Sunada (1962)7 to locate the root apex
for measuring the root canal length.
The presence of extraradicular biofilm on the external surface of the root apex
, even after the endodontic interventions performed, leads to the practical confirmation of all that has been studied about the possible causes of persistence of the periapical lesions being related to this biofilm.
For instance, after dressing with the antibiotic mixture to resist inflammatory reaction, or if the root apex
of the upper posterior tooth is adjacent to maxillary sinus, it may be more difficult to induce enough blood.
Mucosal fenestration is a condition that can be described as breakdown of the overlying bone and alveolar mucosa leading to exposure of root apex
in the oral environment.
