Huakita Nodule - kaiao taupuhipuhi e whakatika hauota

huakita Nodule he microorganisms e no ki te puninga Rhizobium (i te kupu Kariki mo te kupu -. "Living i runga i pakiaka"). E whakaurua ratou ki roto ki te pūnaha pakiaka o nga otaota, a ki reira ora. I te wa ano e kore e ratou pirinoa, t. Ki. Huakita kore anake, engari ano hoki 'aonga te māngai o te otaota. oraraa whaihua pērā o kaiao i huaina symbiosis. I roto i tenei take, kua whakaputaina e te hauota kōhauhau e "hao" te moroiti, me te huakita ratou atu tipu - warowaihā me ngā kohuke. Ētahi iwi whakapono e kua noho enei prokaryotes i roto i te pakiaka māngai anake legume whānau, engari ehara i te mea. He atu tipu whakarato prokaryotes nodule nohonga nei pakiaka - pērā i alder, kakaho ngahere, me te pera i runga i ..

Hoki kaiao āhuatanga Rhizobium puninga e polymorphism, arā. He tino kanorau momo E o huakita. kia ēnei microorganisms turanga, me te pahoho, i te āhua o te coccus ranei Bacillus, filamentary, porotītaha. I roto i te nuinga o taitamariki prokaryotes he tokotoko-āhua, e ki te whakanui ake tau, me te rerekē e tika ana ki te haaputuputuraa o ngā matūkai me te immobilization. I roto i tona huringa ora kaiao haere i roto i te maha o ngā wāhanga, e taea te whakawakia e tona ahua. I te tīmatanga tenei rakau āhua, ka pera-ka karanga "rakau potaea" (he whitiki ki inclusions ngako), me te hopea bakteriod - pūtau pūmau nui kōhikohikotia āhua.

He motuhake huakita Nodule, ie. E., e taea ki te noho anake ratou he rōpū motuhake momo o te tipu ranei. Tenei taonga o microorganisms i hanga ira. nui hoki ko te whai huatanga - te kaha ki te whakaemi hauota kōhauhau i roto i te nui hoki te tipu o ratou ope. E kore te mea tamau tenei taonga, me te kia rerekē tika ki ngā āhuatanga taiao.

Mō pehea huakita nodule tomo te pakiaka, kahore he whakaaro, heoi, i reira e he maha o whakapae e pā ana ki te huarahi o ratou penetration. Hei tauira, whakapono etahi pūtaiao e kua whakaurua prokaryotes ki te pakiaka i roto i tona kino kiko, i te mea etahi e pā ana ki te kătahi roto i te makawe pakiaka. He he ano hoki te whakapae auxin - te whakaaro e te pūtau amiorangi, e tauturu i te huakita ki kia whakaurua ki roto ki te pūtau pakiaka.

puta te tino taua implantation i roto i rua ngā wāhanga: tuatahi - mate o makawe pakiaka, a ka - te hanganga o nodules. He rerekē te roanga o te wāhanga, me te tei runga i te momo o te tipu.

Te tikanga o huakita e he taea ki te whakatika hauota, he nui hoki te ahuwhenua, t. K. taea ēnei rauropi haamaitai hua. Mai i enei microorganisms rite tongi kitakita te, e whakamahia nei mo nga purapura maimoatanga i leguminous e whakatairanga pakiaka tere pangia. momo rerekē o papilionaceous whānau taunga noa i runga i te rawakore oneone e kore e rapua e atu tongi hauota. Na, whakawhiti i 1 heketea o pini "i roto i" ki te rhizobia i roto i te tau ki te āhua here o 100-400 kg o hauota.

Ko te kupu, huakita nodule - kaiao taupuhipuhi, e he tino nui e kore anake i roto i te ora o te tipu, engari ano hoki te huringa hauota i roto i te natura.
