Turning Meristems into Fortresses.

open access: yesTrends in Plant Science, 2019
TERMINAL FLOWER1 (TFL1) was named from knockout Arabidopsis thaliana mutants in which the inflorescence abnormally terminates into a flower. In wild type plants, the expression of TFL1 in the center of the inflorescence meristem represses the flower ...

Grass meristems I: shoot apical meristem maintenance, axillary meristem determinacy and the floral transition. [PDF]

open access: yesPlant 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.

The Secrets of Meristems Initiation: Axillary Meristem Initiation and Floral Meristem Initiation

open access: yesPlants, 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 ...

Variables Affecting Shoot Growth and Plantlet Recovery in Tissue Cultures of Drug-Type Cannabis sativa L.

open access: yesFrontiers in Plant Science, 2021
Tissue culture approaches are widely used in crop plants for the purposes of micropropagation, regeneration of plants through organogenesis, obtaining pathogen-free plantlets from meristem culture, and developing genetically modified plants.

Regulation of Shoot Apical Meristem and Axillary Meristem Development in Plants [PDF]

open access: yesInternational 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 ...

The leaf meristem enigma: The relationship between the plate meristem and the marginal meristem

open access: yesThe 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

Developmental Morphology and Anatomy Shed Light on Both Parallel and Convergent Evolution of the Umbellate Inflorescence in Monocots, Underlain by a New Variant of Metatopy

open access: yesFrontiers in Plant Science, 2022
Inflorescence structure is very diverse and homoplasious, yet the developmental basis of their homoplasy is poorly understood. To gain an understanding of the degree of homology that these diverse structures share, we characterize the developmental ...

Transcript Profiling of MIKCc MADS-Box Genes Reveals Conserved and Novel Roles in Barley Inflorescence Development

open access: yesFrontiers in Plant Science, 2021
MADS-box genes have a wide range of functions in plant reproductive development and grain production. The ABCDE model of floral organ development shows that MADS-box genes are central players in these events in dicotyledonous plants but the applicability

Plant gene editing through de novo induction of meristems

open access: yesNature Biotechnology, 2019
Plant gene editing is typically performed by delivering reagents such as Cas9 and single guide RNAs to explants in culture. Edited cells are then induced to differentiate into whole plants by exposure to various hormones.

bHLH heterodimer complex variations regulate cell proliferation activity in the meristems of Arabidopsis thaliana

open access: yesiScience, 2022
Summary: Root, shoot, and lateral meristems are the main regions of cell proliferation in plants. It has been proposed that meristems might have evolved dedicated transcriptional networks to balance cell proliferation. Here, we show that basic helix-loop-
