Təsviri və təbii mühiti

Culvularia cinsli göbələklər piqmentli filamentar göbələklərdirlər.Bu cinsli göbələklərin əksər növləri tropik və subtrropik regionlarda taxılların,torpağın,bitkilərin fakultativ patogenləridirlər.Zərərverici olmaları ilə yanaşı onlar həm də insan və heyvanlarda da patogenlik edirlər.

Növləri

Culvularia cinsli göbələklər Curvularia brachyspora,Culvularia clavata,Curvularia pallescens,Curvularia lunata ,Curvularia geniculata,Cuvularia verruculosa və digər bu kimi bir neçə növləri əhatə edir.Curvularia lunata bu cinsli göbələklər içərisində insan və heyvanlarda ən geniş patogenlik edən növdür.

Makroskopik xüsusiyyətləri

Curvularia cinsli göbələklər 25C də PDA mühitində sürətlə böyüyən yumuşaq koloniyalar əmələ gətirir. Koloniyanın rəngi başlanğıcda ağdan çəhrayımtıl boz rəngdə olur,getdikcə koloniuyanın rəngi yetkinlik ilə əlaqədar olaraq zeytuni qəhvəyi yaxud qara rəngdə olur.

Curvularia ( 英語 )

由wikipedia EN提供

Curvularia is a genus of hyphomycete (mold) fungi which can be pathogens but also act as beneficial partners of many plant species. They are common in soil.[1] Most Curvularia species are found in tropical regions, though a few are found in temperate zones.

Curvularia is defined by the type species C. lunata (Wakker) Boedijn.

Curvularia lunata appears as shiny velvety-black, fluffy growth (on the fungus colony surface). These fluffy 'hairs', which really are branching, fine filamentous structures called hyphae, are divided inside by cell walls named septae (-> the hyphae are 'septate'). The walls of these hyphae contain dark pigments, which makes for their black appearance and which is called 'dematiaceous'. The hyphae produce brown spore bearing organs, 'conidiophores', which are distinguished by their 'geniculate' [1] shape, meaning they have bends of abrupt kneelike angles. The immobile, asexual fungal spores born on those conidiophores, the poroconidia, have a slightly to distinctly curved shape; they are divided inside by horizontally spreading cell walls (= are 'transversely[2] septate'), and have one expanded cell (the third[clarification needed] cell) at one end (the pore[clarification needed] end of the conidium).

Curvularia can be distinguished from the species Bipolaris and Drechslera by the way (angle) walls (septae) divide the inner structure of their spores.

The name of the teleomorphic state of the type species Curvularia lunata is Cochliobolus lunatus (Fam. Pleosporaceae, Ord. Pleosporales, Cla. Loculoascomycetes, Phy. Ascomycota).

Heat-tolerance symbiote

One species of Curvularia, Curvularia protuberata, is an endosymbiote of the panic grass Dichanthelium lanuginosum that can enable the grass to thrive near hot springs in soil temperatures of up to 104 °F (40 °C). The fungus confers this protective effect only when itself infected by the Curvularia thermal tolerance virus (CThTV). Plants unrelated to panic grass also experience this protective effect when inoculated with the virus-infected fungus.[2]
