Bakteeriyada Nodule - noolaha u furno in hagaajin nitrogen

bakteeriyada Nodule waa sheyga ay leeyihiin panulirus Rhizobium (ka erayga Giriigga ah ee erayga -. "noolaanshaha on xididdada"). Waxaa loo soo bandhigay galay nidaamka xididka ka mid ah dhirta oo halkaas joogaan. Isla mar ahaantaana, ma ay joogin dulin, t. Si aad. Bakteeriyada Ma aha oo kaliya, laakiin sidoo kale wakiil u ah flora ka faa'iideysteen. jiritaanka labada dhinacba faa'iido noocan oo kale ah ee loo yaqaan noolaha khaasatan. Xaaladdan oo kale, dhirta sii waxa soo saarey nitrogen Hawada oo "qabsado" ayuu sheyga iyo naftooda bakteeriyada - carbohydrates iyo macdanta. Dadka qaar ayaa rumeysan in prokaryotes kuwaas oo degay xididada wakiilada kaliya legume qoyska, laakiin ma aha. Waxaa jira dhirta kale kuwaas oo xididdada ka bixiyaan prokaryotes nodule degaanka - sida Alder, kaynta cawsduurka iyo wixii la mid ah ..

Waayo, noolaha Rhizobium panulirus waxa lagu gartaa polymorphism, ie. Foomamka E bakteeriyada yihiin kuwo aad u kala duwan. sheyga waxaa laga yaabaa in la dhaqaajin karo oo taagan, waxay leeyihiin qaab reer coccus ama Bacillus, filamentary, gadood. In ugu prokaryotes yar yihiin ul-qaabeeya, kaas oo la da'da kordhaysa oo kala duwan ay sabab u raasamaal ee nafaqooyinka iyo joojin. In ay wareegga nolosha shaqeeyo maraa heerar kala duwan, kaas oo lagu xukumi karaa by muuqaalkiisa. Markii hore ulaha qaabka this, ka dibna waxa loogu yeero "ulaha belted" (leeyahay suumanka la inclusions baruurta) iyo ugu dambeyntii bakteriod - caadi ahayn qaabeeya cell go'an waaweyn.

bakteeriyada Nodule yihiin gaar ah, E. ie., Waxay awoodaan si ay u degaan oo kaliya waa koox gaar ah ama nooca geedka. Tani waxay hanti ah sheyga hiddo sameeyay. Sidoo kale muhiim u tahay waxtarka - awood u leh inay isku uruursadaan nitrogen atmosfeerta in tiro ku filan geedka ay martida u. hantida Tani ma aha joogto ah iyo kala duwanaan karaan sabab u tahay xaaladaha deegaanka.

Ku saabsan sida bakteeriyada nodule geli xididka, ma jiro iswaafiqitaan, si kastaba ha ahaatee, waxaa jira tiro ka mid ah fikradaha ku saabsan hab ay of ay wax lays. Tusaale ahaan, saynisyahano qaar ka mid ah waxay aaminsan yihiin in prokaryotes ayaa lagu bilaabaa galay xididka iyada oo ay dhaawac jirka, halka qaar kalena waxay yidhaahdeen ku saabsan wax lays iyada oo loo marayo timaha xididka. Waxa kale oo jira waa fikrad ah auxin - male ah in unugyada satellite ah, taas oo ka caawin bakteeriyada in la keeno unugyada xididka.

The ku rakibida aad isku dhacaa laba weji: marka hore - caabuq of timaha xidid, ka dibna - formation of qanjira. Muddada wajiga waa ka duwan yahay oo ay ku xiran tahay nooca geedka.

Taasoo la micno ah bakteeriyada oo ay awoodaan si uu u xaliyo nitrogen, waa weyn yahay, waayo, K. noolaha Kuwani hagaajin karo wax soo saarka beeraha, t.. From kuwan sheyga bacrimin bakteeriyada waa la diyaariyey, kaas oo waxaa loo isticmaalaa abuurka daaweynta ka leguminous in kor xididdada dhakhso cudurka ka. Noocyada kala duwan ee papilionaceous qoyska degtey xitaa on carradu saboolka ah uma baahna bacriminta nitrogen oo dheeraad ah. Sidaas daraaddeed, 1 hektar oo digir ah "in" la rhizobia sanadka gudihiisa tarjumaysaa gobolka xidhxidhan of 100-400 kg of nitrogen.

Sayidka, bakteeriyada nodule - noolaha u furno, kuwaas oo aad u muhiim ah ma aha oo kaliya ee nolosha ee warshadda, laakiin sidoo kale wareegga nitrogen ee dabiiciga ah.
