LITERATURE ANALYSIS OF PHYLOTAXIS PATTERN VARIATION IN PLANTS: SYMMETRY, CLASSIFICATION, AND SPECIES REPRESENTATION
Bio-Lectura : Jurnal Pendidikan Biologi; Vol. 12 No. 1 (2025); 127-137
Phyllotaxis, or the pattern of leaf arrangement along a plant stem, plays a crucial role in physiological efficiency and morphological adaptation. This study aims to examine the variation in phyllotactic patterns among plants, identify their relation...

The CUP-SHAPED COTYLEDON2 and 3 genes have a post-meristematic effect on Arabidopsis thaliana phyllotaxis
Ann Bot
Background and Aims The arrangement of flowers in inflorescence shoots of Arabidopsis thaliana represents a regular spiral Fibonacci phyllotaxis. However, in the cuc2 cuc3 double mutant, flower pedicels are fused to the inflorescence stem, and phyllo...

A stochastic multicellular model identifies biological watermarks from disorders in self-organized patterns of phyllotaxis
eLife
Exploration of developmental mechanisms classically relies on analysis of pattern regularities. Whether disorders induced by biological noise may carry information on building principles of developmental systems is an important debated question. Here...

Mathematical model studies of the comprehensive generation of major and minor phyllotactic patterns in plants with a predominant focus on orixate phyllotaxis
PLoS Comput Biol
Plant leaves are arranged around the stem in a beautiful geometry that is called phyllotaxis. In the majority of plants, phyllotaxis exhibits a distichous, Fibonacci spiral, decussate, or tricussate pattern. To explain the regularity and limited vari...

Biophysical optimality of the golden angle in phyllotaxis
Sci Rep
Plant leaves are arranged around a stem axis in a regular pattern characterized by common fractions, a phenomenon known as phyllotaxis or phyllotaxy. As plants grow, these fractions often transition according to simple rules related to Fibonacci sequ...

Noise and Robustness in Phyllotaxis
PLoS Comput Biol
A striking feature of vascular plants is the regular arrangement of lateral organs on the stem, known as phyllotaxis. The most common phyllotactic patterns can be described using spirals, numbers from the Fibonacci sequence and the golden angle. This...

Meristem identity and phyllotaxis in inflorescence development
Front Plant Sci
Inflorescence morphology is incredibly diverse. This diversity of form has been a fruitful source of inquiry for plant morphologists for more than a century. Work in the grasses (Poaceae), the tomato family (Solanaceae), and Arabidopsis thaliana (Bra...

Developmental stochasticity and variation in floral phyllotaxis
J Plant Res
Floral phyllotaxis is a relatively robust phenotype; trimerous and pentamerous arrangements are widely observed in monocots and core eudicots. Conversely, it also shows variability in some angiosperm clades such as ‘ANA’ grade (Amborellales, Nymp...

Whole-Heart Coronary MR Angiography Using a 3D Cones Phyllotaxis Trajectory
Magn Reson Med
PURPOSE: To develop a 3D cones steady state free precession sequence with improved robustness to respiratory motion while mitigating eddy current artifacts for free-breathing whole-heart coronary magnetic resonance angiography. METHOD: The proposed s...

Evolutionary origins of Fibonacci phyllotaxis in land plants
Heliyon
Fibonacci phyllotaxis is commonly seen in all major groups of land plants. While a precise correlation is found between the internal pattern of the primary vascular system and the external pattern of appendages on the stem surface, it remains a big q...

A new mathematical model of phyllotaxis to solve the genuine puzzle spiromonostichy
J Plant Res
Arrangement of plant leaves around the stem, termed phyllotaxis, exhibits beautiful and mysterious regularities and has been one of the most attractive subjects of biological pattern formation. After the long history of studies on phyllotaxis, it is ...

A plausible model of phyllotaxis
Proc Natl Acad Sci U S A
A striking phenomenon unique to the kingdom of plants is the regular arrangement of lateral organs around a central axis, known as phyllotaxis. Recent molecular-genetic experiments indicate that active transport of the plant hormone auxin is the key ...

Phyllotaxis Turns Over a New Leaf—A New Hypothesis
Int J Mol Sci
Phyllotaxis describes the periodic arrangement of plant organs most conspicuously floral. Oscillators generally underlie periodic phenomena. A hypothetical algorithm generates phyllotaxis regulated by the Hechtian growth oscillator of the stem apical...
PubMed
Meristem size contributes to the robustness of phyllotaxis in Arabidopsis
J Exp Bot
Using the plant model Arabidopsis, the relationship between day length, the size of the shoot apical meristem, and the robustness of phyllotactic patterns were analysed. First, it was found that reducing day length leads to an increased meristem size...
PubMed
The arrangement of lateral veins along the midvein of leaves is not related to leaf phyllotaxis
Sci Rep
Positions of leaves along a stem usually adhere to a genetically determined, species-specific pattern known as a leaf phyllotaxis. We investigated whether the arrangement of lateral secondary veins along primary midveins adhered to a species-specific...
PubMed
Phyllotaxis without symmetry: what can we learn from flower heads?
J Exp Bot
Phyllotaxis is commonly considered in the context of circular meristems or receptacles, yet non-circular (fasciated) structures also give rise to new primordia and organs. Here we investigate phyllotactic patterns in fasciated flower heads in the Ast...

Fibonacci spirals may not need the Golden Angle
Quant Plant Biol
Phyllotaxis, the regular arrangement of plant lateral organs, is an important aspect of quantitative plant biology. Some models relying on the geometric relationship of the shoot apex and organ primordia focus mainly on spiral phyllotaxis, a common p...

Floral development and floral phyllotaxis in Anaxagorea (Annonaceae)
Ann Bot
BACKGROUND AND AIMS: Anaxagorea is the phylogenetically basalmost genus in the large tropical Annonaceae (custard apple family) of Magnoliales, but its floral structure is unknown in many respects. The aim of this study is to analyse evolutionarily i...

Spatial regularity control of phyllotaxis pattern generated by the mutual interaction between auxin and PIN1
PLoS Comput Biol
Phyllotaxis, the arrangement of leaves on a plant stem, is well known because of its beautiful geometric configuration, which is derived from the constant spacing between leaf primordia. This phyllotaxis is established by mutual interaction between a...
