Oide and Ninomiya (2000) used the Elliptic Fourier (EF) method to classify soybean varieties, using a normalized leaf shape. The EF method using a chain-coded, closed-contour, invariant to scale, translation and rotation was first introduced by Kuhl and Giardina (1982). EF has been used in...
identification of ferns include such aspects of the mature sporophyte plant as differences in the stem, frond, sporophyll, sporangium, and position of the sporangium and the absence or presence, as well as the shape, of the indusium (a membranous outgrowth of the leaf) covering the sporangia...
Date or Date Palm is a species from Palm family i.e., a flowering plant species cultivated in order to obtain edible, sweet and an elongated shape fruit which is consumed as staple food in Middle East and mostly found in North Africa and South Asia as well as in so many tropical and ...
Here we provide the ‘Global Spectrum of Plant Form and Function Dataset’, containing species mean values for six vascular plant traits. Together, these traits –plant height, stem specific density, leaf area, leaf mass per area, leaf nitrogen content per dry mass, and diaspore (seed or spor...
In most disease resistance responses, microbial signals are recognized by extra- or intracellular receptors. The interactions tend to be species specific and it is unclear how they shape leaf microbial communities. In natural habitats, microbe–microbe interactions are also important for shaping leaf ...

The plant leaf veins play a key role in transporting photoassimilates and water and providing mechanical support of leaf.Though the leaf morphology and structure looks plain,the molecular mechanism of plant leaf vein development is very complicated.A series of studies demonstrate that leaf vein devel...

Plant Defenses and Predation Risk Differentially Shape Patterns of Consumption, Growth, and Digestive Efficiency in a Guild of Leaf-Chewing Insects 来自 学术范 喜欢 0 阅读量: 30 作者:K Ian,SH Mcart,JS Thaler,D Nicolas 摘要: Herbivores are squeezed between the two omnipresent threats of variable...
Root exudates are plant-derived, exported metabolites likely shaping root-associated microbiomes by acting as nutrients and signals. However, root exudation dynamics are unclear and thus also, if changes in exudation are reflected in changes in microbiom
