Butterfly Learning and the Diversification of Plant Leaf Shape
, 2016 Visual cues are important for insects to find flowers and host plants. It has been proposed that the diversity of leaf shape in Passiflora vines could be a result of negative frequency dependent selection driven by visual searching behavior among their ...

Leaf area–length allometry and its implications in leaf shape evolution [PDF]
Trees, 2019 According to Thompson’s principle of similarity, the area of an object should be proportional to its length squared. However, leaf area-length data of some plants have been demonstrated not to follow the principle of similarity. We explore the reasons why the leaf area-length allometry deviates from the principle of similarity and examine whether there

Molecular Oncology, EarlyView.Glioma cells mainly express the endothelin receptor EDNRB, while EDNRA is restricted to a perivascular tumor subpopulation. Endothelin signaling reduces glioma cell proliferation while promoting migration and a proneural‐to‐mesenchymal transition associated with poor prognosis. This pathway activates Ca2+, K+, ERK, and STAT3 signalings and is regulated

NARROW LEAF 7 controls leaf shape mediated by auxin in rice [PDF]
Molecular Genetics and Genomics, 2008 Elucidation of the genetic basis of the control of leaf shape could be of use in the manipulation of crop traits, leading to more stable and increased crop production. To improve our understanding of the process controlling leaf shape, we identified a mutant gene in rice that causes a significant decrease in the width of the leaf blade, termed narrow ...

Invariant leaf image recognition with histogram of Gaussian convolution vectors
, 2020 Employing leaf shape features for plant species recognition, especially for cultivar recognition is very challenging due to the high similarities of leaf shapes across different species and cultivars.

Guiding AlphaFold to predict how Munc13‐1 opens Syntaxin‐1
FEBS Open Bio, EarlyView.The syntaxin‐1 Habc‐domain (orange), linker (pink) and SNARE motif (yellow) form a closed conformation that binds to Munc18‐1 (violet) and is opened by the Munc13‐1 MUN domain (cyan) to form the SNARE complex that triggers neurotransmitter release.

Comparison of the Leaf Shape in 2 Reynoutria Species by Quantification of Leaf-base Shape [PDF]
, 2010 The purpose of this report is to quantify leaf-base shapes for the field survey of plants. We analyzed the property of cardioid (limacon) curve, r＝(1－k) + k cos (sita), and confirmed that the coefficient k was able to express the leaf-base shapes ...
