The column, or technically the gynostemium, is a reproductive structure that can be found in several plant families: Aristolochiaceae, Orchidaceae, and Stylidiaceae. It is derived from the fusion of both male and female parts ( stamens and pistil ) into a single organ. [ 1 ]
The Winogradsky column is a simple device for culturing a large diversity of microorganisms. Invented in the 1880s by Sergei Winogradsky , the device is a column of pond mud and water mixed with a carbon source such as newspaper (containing cellulose ), blackened marshmallows or egg-shells (containing calcium carbonate ), and a sulfur source ...

The project successfully sequenced the transcriptomes (expressed genes) of 1,000 different plant species by 2014; [1] [2] its final capstone products were published in 2019. [ 3 ] [ 4 ] [ 5 ] 1KP was a large-scale (involving many organisms) sequencing projects designed to take advantage of the wider availability of high-throughput ("next ...
The hierarchy of biological classification's eight major taxonomic ranks.Intermediate minor rankings are not shown. In botanical nomenclature, variety (abbreviated var.; in Latin: varietas) is a taxonomic rank below that of species and subspecies, but above that of form. [1]
An image of multiple chromosomes, taken from many cells. Plant genetics is the study of genes, genetic variation, and heredity specifically in plants. [1] [2] It is generally considered a field of biology and botany, but intersects frequently with many other life sciences and is strongly linked with the study of information systems.
"On the Tendency of Species to form Varieties; and on the Perpetuation of Varieties and Species by Natural Means of Selection" is the title of a journal article, comprising and resulting from the joint presentation of two scientific papers to the Linnean Society of London on 1 July 1858: On The Tendency of Varieties to Depart Indefinitely from the Original Type by Alfred Russel Wallace and an ...
Plant reproduction is the production of new offspring in plants, which can be accomplished by sexual or asexual reproduction. Sexual reproduction produces offspring by the fusion of gametes, resulting in offspring genetically different from either parent.
