Monotropa uniflora, an obligate myco-heterotroph known to parasitize fungi belonging to the Russulaceae. [1]Myco-heterotrophy (from Greek μύκης mýkes ' fungus ', ἕτερος héteros ' another ', ' different ' and τροφή trophé ' nutrition ') is a symbiotic relationship between certain kinds of plants and fungi, in which the plant gets all or part of its food from parasitism upon ...
' underground '; from Ancient Greek ὑπό (hupó) 'under' and γῆ (gê) 'earth') [1] are biological terms describing an organism's activity below the soil surface. In botany , a seed is described as showing hypogeal germination when the cotyledons of the germinating seed remain non-photosynthetic , inside the seed shell, and below ground. [ 2 ]
Eunicella singularis, the white gorgonian, is a species of colonial soft coral, a sea fan in the family Gorgoniidae. It is found in the western Mediterranean Sea , Adriatic Sea and Ionian Sea. It was first described in 1791 by the German naturalist Eugenius Johann Christoph Esper .
Unlike most plants they do not have chlorophyll and therefore are non-photosynthetic; rather, they are myco-heterotrophs that obtain food through parasitism on subterranean fungi. Because they do not need any sunlight to live, they can live in very dark sites such as the floor of deep forest. The name "Monotropa" is Greek for "one turn" as ...
The overall morphology of these plants is highly reduced compared to other members of the Ericaceae, which are practically all subshrubs, shrubs, or trees.By contrast, the Monotropoideae are all herbaceous perennials, in which an annual shoot reemerges seasonally (in spring or early summer, depending on climate) from a perennial root.
Photosynthetic organisms with plastids of different origin (such as brown algae) do not belong to the Archaeplastida. The archaeplastidans fall into two main evolutionary lines. The red algae are pigmented with chlorophyll a and phycobiliproteins , like most cyanobacteria, and accumulate starch outside the chloroplasts.
The Rhizaria are a diverse and species-rich supergroup of mostly unicellular [3] eukaryotes. [4] Except for the Chlorarachniophytes and three species in the genus Paulinella in the phylum Cercozoa, they are all non-photosynthetic, but many Foraminifera and Radiolaria have a symbiotic relationship with unicellular algae. [5]
In addition, new data also suggests that AM fungi host plants also secrete chemical factors that attract and enhance the growth of developing spore hyphae towards the root system. [ 14 ] The necessary components for the colonization of Glomeromycota include the host's fine root system, proper development of intracellular arbuscular structures ...
