  2. Introgressive hybridization in plants - Wikipedia

    en.wikipedia.org/wiki/Introgressive...

    One study exploring the extent of introgression among three species of poplar trees (P. balsamifera, P. angustifolia and P. trichocarpa) conducted along the Rock Mountain range in the U.S. and Canada found extensive introgression in areas of species converge. Genomic sequencing even showed a trispecies hybrid in these overlapping areas.

  3. Plant morphology - Wikipedia

    en.wikipedia.org/wiki/Plant_morphology

    The plant morphologist goes further, and discovers that the spines of cactus also share the same basic structure and development as leaves in other plants, and therefore cactus spines are homologous to leaves as well. This aspect of plant morphology overlaps with the study of plant evolution and paleobotany.

  4. Plant genetics - Wikipedia

    en.wikipedia.org/wiki/Plant_genetics

    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.

    A multicellular, glandular hair that usually produces a mucilaginous substance and is located on sepal s, stipules, or petioles, or on nearby parts of stem s; commonly found on plants in the order Gentianales. columella In flowering plants, the central axis of the cone or fruit, e.g. in Callitris. column 1.

  6. Stratification (vegetation) - Wikipedia

    en.wikipedia.org/wiki/Stratification_(vegetation)

    These vegetation layers are primarily determined by the height of their individual plants, the different elements may however have a range of heights. The actual layer is characterised by the height range in which the vast majority of photosynthetic organs (predominantly leaves) are found. Taller species will have part of their shoot system in ...

  7. Peripatric speciation - Wikipedia

    en.wikipedia.org/wiki/Peripatric_speciation

    Peripatric speciation is a mode of speciation in which a new species is formed from an isolated peripheral population. [1]: 105 Since peripatric speciation resembles allopatric speciation, in that populations are isolated and prevented from exchanging genes, it can often be difficult to distinguish between them, [2] and peripatric speciation may be considered one type or model of allopatric ...

  8. Plant evolutionary developmental biology - Wikipedia

    en.wikipedia.org/wiki/Plant_evolutionary...

    Gérard Cusset provided a detailed in-depth analysis of the history of plant morphology, including plant development and evolution, from its beginnings to the end of the 20th century. [18] Rolf Sattler discussed fundamental principles of plant morphology [ 19 ] [ 20 ] and plant evo-devo.

  9. Pleiotropy - Wikipedia

    en.wikipedia.org/wiki/Pleiotropy

    Similar predictors exist for plant and animal species and are used in agricultural breeding. One measure of pleiotropy is the fraction of genetic variance that is common between two distinct complex human traits: e.g., height vs bone density, breast cancer vs heart attack risk, or diabetes vs hypothyroidism risk.
