Primary and secondary thickening in the stem of Cordyline fruticosa (Agavaceae) [PDF]
Anais da Academia Brasileira de Ciências, 2010 The growth in thickness of monocotyledon stems can be either primary, or primary and secondary. Most of the authors consider this thickening as a result of the PTM (Primary Thickening Meristem) and the STM (Secondary Thickening Meristem) activity.

Auxin Modulated Initiation of Lateral Roots Is Linked to Pericycle Cell Length in Maize
Frontiers in Plant Science, 2019 Auxin is essential for the regulation of root system architecture by controlling primary root elongation and lateral root (LR) formation. Exogenous auxin has been reported to inhibit primary root elongation and promote the formation of LRs. In this study,

Morpho-Anatomical Analysis of the Rhizome in Species of Scleria Berg. (Cyperaceae) from Serra do Cipó (MG) [PDF]
Brazilian Archives of Biology and Technology, 2009 Aspects related to the nature of stem thickening in monocotyledons have been the subject of many studies. Primary thickening has been attributed to the Primary Thickening Meristem (PTM).

UPRA-PHYSIOLOGICAL LEVELS OF GIBBERELLINS / DELLAS MODIFY ROOT CELL SIZE / NUMBER AND ROOT ARCHITECTURE IN ROOT TIPS OF ARABIDOPSIS THALIANA SEEDLINGS. CONNECTIONS TO THE ROOT HAIR PATTERNING AND ABUNDANCE [PDF]
Journal of Plant Development, 2021 A previous study showed that excessive GAs/DELLAs altered the arrangement, shape and frequency of hairs in root tips of A. thaliana seedlings by acting from the root sub-epidermal tissues.

Control of lateral root initiation by DA3 in Arabidopsis
Cell Reports, 2023 Summary: Lateral root (LR) initiation is controlled by the pericycle and the neighboring endodermis in Arabidopsis. Here, we demonstrate that UBIQUITIN-SPECIFIC PROTEASE14/DA3 regulates LR initiation by modulating auxin signaling in the pericycle and ...
