Land plants (Embryophyta)

2009
Abstract Land plants (embryophytes) constitute a monophyletic group that is well supported by morphological and molecular characters. Numerous vegetative and reproductive traits directly associated with life on land characterize the group (1) (Fig. 1).

Investigations on Carotenoids in Embryophyta. I. Bryophyta

The Bryologist, 1980
The author has investigated the carotenoids in 4 Hepaticae and 22 Musci. By means of column and thin-layer chromatography, the following carot- enoids were found to be present: lycopene, a-carotene, p-carotene, y-carotene, f-carotene epoxide, P-carotene diepoxide, /P-cryptoxanthin, lutein, lutein epoxide, zeaxanthin, antheraxanthin, neoxanthin ...

A methodology for the prediction of Embryophyta protein functions using mismatch kernels

2015 20th Symposium on Signal Processing, Images and Computer Vision (STSIVA), 2015
This work implements a type of string kernel called Mismatch kernel, together with a methodology involving Support Vector Machines (SVM) for solving 14 molecular function classification problems of land plants (Embryophyta). The implemented methodology uses metaheuristic bio-inspired algorithms for finding optimal hyperparameters of the SVM, to solve ...

The tapetum: Its form, function, and possible phylogeny inEmbryophyta

Plant Systematics and Evolution, 1985
It appears that the tapetum is universally present in land plants, even though it is sometimes difficult to recognize, because it serves mostly as a tissue for meiocyte/spore nutrition. In addition to this main function, the tapetum has other functions, namely the production of the locular fluid, the production and release of callase, the conveying of ...

The photoconvertible water-soluble chlorophyll-binding protein of Chenopodium album is a member of DUF538, a superfamily that distributes in Embryophyta

Journal of Plant Physiology, 2013
Various plants possess hydrophilic chlorophyll (Chl) proteins known as water-soluble Chl-binding proteins (WSCPs). WSCPs exist in two forms: Class I and Class II, of which Class I alone exhibits unique photoconvertibility. Although numerous genes encoding Class II WSCPs have been identified and the molecular properties of their recombinant proteins ...

The polyketide pathway in sporopollenin biosynthesis is specific to land plants (Embryophyta)

AbstractBackground and AimsSporopollenin (SP) is a complex biopolymer in the outer wall of spores and pollen and provides protection from environmental stresses. Its extraordinary chemical resistance, especially to acetolysis, was widely used to identify SP in biological specimens. This broad definition of SP led to claims for its widespread occurrence
