Xlamidamonada

Xlamidomonada
Kenja turkum:	Xlamidamonalar

*Chlamydomonas caudata Villening* rasmlari.

*Chlamydomonas reinhardtii* hujayrasining koʻndalang kesimi

Pastki chap tomonda ikkita flagella bilan *xlamidomonasning* yorugʻlik mikrografi

*Chlamydomonas globosa*, yana ikkita flagella bilan pastki chap tomonda koʻrinadi

Xlamidomonada – yashil suv oʻtlari turkumi, 150 ga yaqin turdagi^[1] bir hujayrali flagellatlardan iborat boʻlib, turgʻun suvda va namda uchraydi. tuproqda, chuchuk suvda, dengiz suvida va hatto qorda „qor yosunlari“ sifatida^[2]. Chlamydomonas molekulyar biologiya uchun namuna organizm sifatida ishlatiladi, ayniqsa flagellar harakatchanligi va xloroplast dinamikasi, biogenez va genetika tadqiqotlari. Chlamydomonasning koʻplab ajoyib xususiyatlaridan biri shundaki, u yorugʻlik bilan bevosita faollashtirilgan ion kanallarini (kanalrodopsinlar) oʻz ichiga oladi. Chlamydomonasning baʼzi tartibga solish tizimlari Gymnospermlarda ularning homologlariga qaraganda murakkabroq, evolyutsiya bilan bogʻliq tartibga soluvchi oqsillar kattaroq va qoʻshimcha domenlarni oʻz ichiga oladi^[3].

Molekulyar filogeniya tadqiqotlari shuni koʻrsatdiki, morfologik maʼlumotlardan foydalangan holda aniqlangan anʼanaviy Chlamydomonas jinsi Volvocales ichida polifiletik edi. Keyinchalik koʻplab turlar qayta tasniflandi (masalan, Oogamochlamys, Lobochlamys) va boshqa koʻplab „Chlamydomonas“ sl avlodlari hali ham qayta tasniflanishi kerak^[4]^[5]^[6].
