Performance assessment of three simplified Gielis equations in quantifying the geometries of lanceolate bamboo leaves

open access: yesFrontiers in Plant Science
Accurate quantification of bamboo leaf morphology is essential for understanding plant morphogenesis and development. However, most bamboo leaves exhibit long lanceolate shape characteristic, posing challenges in finding suitable mathematical models for ...

Developing an Accurate and Fast Non-Destructive Single Leaf Area Model for Loquat (Eriobotrya japonica Lindl) Cultivars

open access: yesPlants, 2019
In this research, seven different models to predict leaf area (LA) of loquat (Eriobotrya japonica Lindl) were tested and evaluated. This species was chosen due to the relevant importance of its fruit as an appreciated early summer product and of its ...

The shapes of wine and table grape leaves: An ampelometric study inspired by the methods of Pierre Galet

open access: yesPlants, People, Planet, 2021
Societal Impact Statement Leaf shapes are critical to the identification of grapevine varieties. Historically, measures of grapevine leaves were used to enforce appellation law and leaf shape is used to this day to distinguish economically important ...

Heterophylly Quantitative Trait Loci Respond to Salt Stress in the Desert Tree Populus euphratica

open access: yesFrontiers in Plant Science, 2021
Heterophylly, or leaf morphological changes along plant shoot axes, is an important indicator of plant eco-adaptation to heterogeneous microenvironments.

ABL kinase‐dependent phosphorylation of SH proteins promotes their direct interaction with CRK family SH2 domains

open access: yesFEBS Letters, EarlyView.
CT10 regulator of kinase (CRK) and CRK‐Like (CRKL) are signaling adaptors driving cell adhesion, motility, differentiation, and proliferation. SH2‐domain containing (SH) proteins are enriched in YXXP motifs which when phosphorylated create preferred binding sites for CRK family SH2 domains.

Topological Data Analysis as a Morphometric Method: Using Persistent Homology to Demarcate a Leaf Morphospace

open access: yesFrontiers in Plant Science, 2018
Current morphometric methods that comprehensively measure shape cannot compare the disparate leaf shapes found in seed plants and are sensitive to processing artifacts.

Reconstructing enzyme evolution by protein engineering

open access: yesFEBS Letters, EarlyView.
Natural enzyme evolution can be retraced by protein engineering methods such as directed evolution, rational design, and ancestral sequence reconstruction. These approaches reveal how enzymes emerged from ligand‐binding scaffolds, developed varying substrate preferences, formed oligomeric complexes, adapted to environmental changes, and evolved novel ...

Leaf morphological traits show greater responses to changes in climate than leaf physiological traits and gas exchange variables

open access: yesEcology and Evolution
Adaptation to changing conditions is one of the strategies plants may use to survive in the face of climate change. We aimed to determine whether plants' leaf morphological and physiological traits/gas exchange variables have changed in response to ...

What determines a leaf's shape? [PDF]

open access: yesEvoDevo, 2014
The independent origin and evolution of leaves as small, simple microphylls or larger, more complex megaphylls in plants has shaped and influenced the natural composition of the environment. Significant contributions have come from megaphyllous leaves, characterized usually as flat, thin lamina entrenched with photosynthetic organelles and stomata ...

Comparison of half and full-leaf shape feature extraction for leaf classification [PDF]

open access: yes, 2016
Shape is the main information for leaf feature that most of the current literatures in leaf identification utilize the whole leaf for feature extraction and to be used in the leaf identification process.In this paper, study of half-leaf features ...
