The Secrets of Meristems Initiation: Axillary Meristem Initiation and Floral Meristem Initiation
Plants, 2023 The branching phenotype is an extremely important agronomic trait of plants, especially for horticultural crops. It is not only an important yield character of fruit trees, but also an exquisite ornamental trait of landscape trees and flowers. The branching characteristics of plants are determined by the periodic initiation and later development of ...

The leaf meristem enigma: The relationship between the plate meristem and the marginal meristem
The Plant Cell, 2021 AbstractLeaf organogenesis is governed by the spatiotemporal activity of the leaf meristem, which has far greater mitotic activity than the shoot apical meristem. The two types of leaf meristems, the plate meristem and the marginal meristem, are distinguished by the location and longevity of their cell proliferative activity. Most leaf lamina outgrowth

Regulation of Shoot Apical Meristem and Axillary Meristem Development in Plants [PDF]
International Journal of Molecular Sciences, 2020 Plants retain the ability to produce new organs throughout their life cycles. Continuous aboveground organogenesis is achieved by meristems, which are mainly organized, established, and maintained in the shoot apex and leaf axils. This paper will focus on reviewing the recent progress in understanding the regulation of shoot apical meristem and ...

Grass Meristems I: Shoot Apical Meristem Maintenance, Axillary Meristem Determinacy and the Floral Transition [PDF]
Plant and Cell Physiology, 2013 The vegetative and reproductive shoot architectures displayed by members of the grass family are critical to reproductive success, and thus agronomic yield. Variation in shoot architecture is explained by the maintenance, activity and determinacy of meristems, pools of pluripotent stem cells responsible for post-embryonic plant growth.

Plant Meristems: Cytokinins — The Alpha and Omega of the Meristem [PDF]
Current Biology, 2007 Recent studies have revealed important new details of how cytokinin-dependent mechanisms control plant growth. Intriguingly, cytokinins are involved in both maintaining meristems and promoting differentiation.

Pattern formation during de novo assembly of the Arabidopsis shoot meristem [PDF]
, 2007 Most multicellular organisms have a capacity to regenerate tissue after wounding. Few, however, have the ability to regenerate an entire new body from adult tissue. Induction of new shoot meristems from cultured root explants is a widely used, but poorly

Vegetative Apical Meristems. [PDF]
The Plant Cell, 1992 A fascinating aspect of plant biology is that a small cell group is the origin of shoot systems as varied as redwood trees or Arabidopsis. The first recognition that shoot systems originate from small groups of cells was by Kaspar Wolff in 1759 (cited in Cutter, 1965). These small groups of cells are known as shoot apical meristems.

Behavior of Leaf Meristems and Their Modification [PDF]
Frontiers in Plant Science, 2015 A major source of diversity in flowering plant form is the extensive variability of leaf shape and size. Leaf formation is initiated by recruitment of a handful of cells flanking the shoot apical meristem (SAM) to develop into a complex three-dimensional structure.

AXR1 acts after lateral bud formation to inhibit lateral bud growth in Arabidopsis [PDF]
, 1999 The AXR1 gene of Arabidopsis is required for many auxin responses. The highly branched shoot phenotype of mature axr1 mutant plants has been taken as genetic evidence for a role of auxin in the control of shoot branching.

Meristem Maintenance in Maize [PDF]
The Plant Cell, 2015 Stem cells in the shoot meristem are the ultimate source of aerial organs in plants. They shape the plant, determining the layout of branches, leaves, and flowers, and allow plants to produce new organs throughout their life cycle.
