Developmental homeostasis is a process in which animals develop more or less normally, despite defective genes and deficient environments. [1] It is an organism's ability to overcome certain circumstances in order to develop normally. This can be a circumstance that interferes with either a physical or mental trait.
During his tenure at the State University of New York at Oneonta, Dr William Butts [1] correctly applied the term homeorhesis to biological organisms. The term was created by C.H. Waddington and first used in biology in his book Strategy of the Genes (1957), where he described the tendency of developing or changing organisms to continue ...
This is a list of genera in the orchid family (Orchidaceae), originally according to The Families of Flowering Plants - L. Watson and M. J. Dallwitz.This list is adapted regularly with the changes published in the Orchid Research Newsletter which is published twice a year by the Royal Botanic Gardens, Kew.
Gene–environment interaction (or genotype–environment interaction or G×E) is when two different genotypes respond to environmental variation in different ways. A norm of reaction is a graph that shows the relationship between genes and environmental factors when phenotypic differences are continuous. [1]
Orchid mycorrhizae are critically important during orchid germination, as an orchid seed has virtually no energy reserve and obtains its carbon from the fungal symbiont. [1] [2] The symbiosis starts with a structure called a protocorm. [3] During the symbiosis, the fungus develops structures called pelotons within the root cortex of the orchid. [4]
The cannabinoid receptor type 1, located at the presynaptic neuron, is a receptor that can stop stressful neurotransmitter release to the postsynaptic neuron; it is activated by endocannabinoids such as anandamide (N-arachidonoylethanolamide) and 2-arachidonoylglycerol via a retrograde signaling process in which these compounds are synthesized ...
Rhizanthella gardneri is a leafless, sympodial herb with a horizontal rhizome 60–120 mm (2.4–4.7 in) below the soil surface. Beginning in late May to early June, the plant produces up to 100 small, inward-facing pinkish to deep red and cream coloured flowers 4–5 mm (0.16–0.20 in) wide, surrounded by six to twelve pinkish-cream bracts.
Rhynchostylis (abbreviated Rhy in the horticultural trade) is a genus in the orchid family (Orchidaceae), closely allied to the genus Vanda (from which it differs in the one-lobed lip of the flower) and comprising four currently accepted species native to the Indian Subcontinent, China, Indochina, Malaysia, Indonesia and the Philippines.
