Taphrina deformans classification essay

Taphrina Fries is a genus of dimorphic ascomycetes comprising more than 90 species distinguished by the specific infections they produce on different vascular plants.

Their filamentous states are restricted to parasitised plant tissue whereas the yeast states are saprobic and can be grown on artificial media. Taphrina deformans Taphrina deformans (Berk. ) Tul (1866) is a causal organism of peach leaf curl disease. Tul (1866) is a causal organism of peach leaf curl disease. However the fungus is not limited only to peach (Prunus persica) and rather attacks the other Prunus species, almond (Prunus amygdalus) but to lesser extent (3).

G. (2003). " Molecular systematics of the dimorphic ascomycete genus Taphrina". Some other representatives of Taphrinomycotina, namely Taphrina maculans, T. farlowii, Protomyces inouyei, P. lactucaedebilis and P. pachydermatis, gave a more diverse picture (Heath et al. 1987). In summary, the Taphrina species showed varying patterns, whereas the three Protomyces species showed similar mitotic patterns.

Peach leaf curl, also known as curly leaf, curly blight or leaf blister, has been recognized as a common disease since the early 1800s. It is caused by the fungus Taphrina deformans and can affect the blossoms, fruit, leaves and shoots of peaches and nectarines. Peach leaf curl is the most common disease found in backyard orchards. The fungus Taphrina deformans causes peach leaf curl. Host Plants. Taphrina deformans can infect peach (Prunus persica) and nectarine (P. persica var.

nucipersica). Description. During cool, wet springs developing leaves become thicker than normal and curled with a yellow to redpurple color. Taphrina deformans, which causes leaf curl of peach, is the most economically important species and has been extensively studied, and its genome sequence is now publicly available (Ciss et al. 2013). Classification kingdom Fungi phylum Ascomycota Taphrina deformans is a fungus and plant pathogen, and a causal agent[s of peach leaf curl.

Taphrina deformans var. armeniaca, Taphrina deformans var. deformans Basionym: Ascomyces deformans Berk.Proceedings of the American Academy of Arts and Sciences 4: 130 (1860) [MB# ADVERTISEMENTS: In this article we will discuss about the life cycle of taphrina, explained with the help of suitable diagrams.

The genus Taphrina (old generic name Exoascus still in use by many authors) contains several species which are very important pathogens. The ascomycetous fungus Taphrina deformans is the agent of peach leaf curl, a worldwide disease of peach potentially devastating to both crop yields and tree longevity.

Taphrina caerulescens is a species of fungus in the Taphrinaceae family. It is a pathogenic Ascomycete fungus that causes Oak Leaf Blister disease on various species of Oak trees (Quercus sp. ). The associated anamorph species is Lalaria coccinea, described in 1990. This disease causes lesions and blisters on Oak leaves. Another sequence retrieved from GenBank corresponding to a strain identified as T.

deformans (MZ109) differed at five nucleotide positions from that of T. deformans CBS 356. 35 but clustered with T. tormentillae (one nucleotide difference), and might thus represent the latter species. Scientists aim to describe a single 'tree of life' that reflects the evolutionary relationships of living things.

However, evolutionary relationships are a matter of ongoing discovery, and there are different opinions about how living things should be grouped and named.
