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. Plant genetics is similar in many ways to animal genetics but differs ...
Arabidopsis thaliana is an annual (rarely biennial) plant, usually growing to 20–25 cm tall. [6] The leaves form a rosette at the base of the plant, with a few leaves also on the flowering stem. The basal leaves are green to slightly purplish in color, 1.5–5 cm long, and 2–10 mm broad, with an entire to coarsely serrated margin; the stem ...
A flagellum (/ f l ə ˈ dʒ ɛ l əm /; pl.: flagella) (Latin for 'whip' or 'scourge') is a hairlike appendage that protrudes from certain plant and animal sperm cells, from fungal spores (), and from a wide range of microorganisms to provide motility.
Plastid. A plastid is a membrane-bound organelle found in the cells of plants, algae, and some other eukaryotic organisms. Plastids are considered to be intracellular endosymbiotic cyanobacteria. [1] Examples of plastids include chloroplasts (used for photosynthesis); chromoplasts (used for synthesis and storage of pigments); leucoplasts (non ...
DNA can be twisted like a rope in a process called DNA supercoiling. With DNA in its "relaxed" state, a strand usually circles the axis of the double helix once every 10.4 base pairs, but if the DNA is twisted the strands become more tightly or more loosely wound. [ 43 ]
Myloplus sauron and Myloplus aylan have flat, blunt teeth used to chew on plants, a stark contrast with the razor-sharp teeth found in piranhas, but similar to their other pacu counterparts.
Chimera (genetics) Two-colored rose chimera. A genetic chimerism or chimera (/ kaɪˈmɪərə / ky-MEER-ə or / kɪˈmɪərə / kim-EER-ə) is a single organism composed of cells with more than one distinct genotype. Animal chimeras can be produced by the merger of two (or more) embryos. In plants and some animal chimeras, mosaicism involves ...
Plant tissue culture is a collection of techniques used to maintain or grow plant cells, tissues, or organs under sterile conditions on a nutrient culture medium of known composition. It is widely used to produce clones of a plant in a method known as micropropagation. Different techniques in plant tissue culture may offer certain advantages ...
