Dionaea muscipula, znana kot Venus Flytrap, je mesojeda rastlina, ki svoj plen ujame s spremenjenimi listi. Mehanizem delovanja vklju\u010duje hiter premik lista, ko pride majhen plen v stik z njim. Takoj se zapre, da se pozneje prebavi. List Venerine pasti je sestavljen iz dla\u010dic, ob\u010dutljivih na dotik, ali spro\u017eilnih dla\u010dic, ki pomagajo pri signalizaciji za past prek akcijskega potenciala, aktiviranega z natrijem.<\/p>\n\n\n\n

Akcijski potencial je na\u010din celi\u010dne signalizacije, ki poteka, ko pozitivno nabiti ioni vstopijo v celice in povzro\u010dijo hitro spremembo elektri\u010dnega okolja v celi\u010dni membrani, da bi dosegli mejno vrednost. To pa po\u0161lje elektri\u010dne signale drugi celici, da se ta aktivno odzove. <\/p>\n\n\n\n

Signal je tako hiter, da plen ujame v nekaj sekundah. <\/p>\n\n\n\n

\u017delodec plen prebavi z encimi, ki jih spro\u0161\u010dajo \u017eleze na listni sluznici. Rastlina absorbira potrebna hranila, da lahko nadaljuje z delovanjem.<\/p>\n\n\n\n

Razlog, opazovanje in eksperimentiranje:<\/strong><\/p>\n\n\n\n

Tako kot \u010dlove\u0161ki mo\u017egani, ki so odgovorni za spremembe napetosti v dolo\u010denih regijah, ki se pojavljajo kot elektri\u010dna aktivnost v obliki akcijskih potencialov, ki potujejo po \u017eiv\u010dnih celicah. Te aktivnosti je mogo\u010de oceniti s tehnikami, kot so magnetoencefalografija, elektroencefalografija in slikanje z magnetno resonanco, za analizo morebitnih motenj in njihovo diagnozo.<\/p>\n\n\n\n

Skupina interdisciplinarnih raziskovalcev je edinstveno magnetno aktivnost Venus flytrap v povezavi z njeno elektri\u010dno signalizacijo prikazala na podoben na\u010din kot pri ljudeh.<\/p>\n\n\n\n

Tudi mehanizem Venus flytrap temelji na akcijskem potencialu, ki povzro\u010da elektri\u010dne signale v sistemu.<\/p>\n\n\n\n

Akcijski potencial Venus Flytrap lahko spro\u017eijo vro\u010dina, mraz, vsebnost vode in drugi mehanski ali okoljski dejavniki. Raziskovalci so uporabili toploto za spro\u017eitev akcijskega potenciala za merjenje magnetnega polja, saj so opazili, da temperatura vpliva na amplitudo akcijskega potenciala.<\/p>\n\n\n\n

Za merjenje biomagnetizma, povezanega z elektri\u010dno aktivnostjo, so uporabili atomske magnetometre. Uporabljeni senzorji so bile steklene celice, napolnjene s parami alkalnih atomov, ki so se odzivale na spremembe biomagnetne aktivnosti.<\/p>\n\n\n\n

Magnetometri za izvajanje meritev potrebujejo magnetno za\u0161\u010diteno okolje. To je previdnostni ukrep, da bi izmerili samo magnetno aktivnost ve\u010dceli\u010dne rastline. To orodje je zelo u\u010dinkovito in ima prednost pred magnetometri s superprevodno kvantno vmesni\u0161ko napravo (SQID), saj jih je mogo\u010de miniaturizirati za optimalno prostorsko lo\u010dljivost pri merjenju podatkov.<\/p>\n\n\n\n

Raziskovalci so zabele\u017eili magnetni signal Venerine mu\u0161nice z amplitudo 0,5 pikotesle, ki je precej \u0161ibkej\u0161a od zemeljskega magnetnega polja. <\/p>\n\n\n\n

Na podlagi tega bi lahko sklepali na uporabnost biomagnetne aktivnosti, ki bi lahko pomagala pri neinvazivni tehniki za odkrivanje stresa.<\/p>\n\n\n\n

Izbolj\u0161anje pridelka je kon\u010dni cilj za odpravo u\u010dinkov, ki jih povzro\u010dajo okoljski dejavniki, kot so temperaturne spremembe, kemi\u010dno delovanje in tudi napad rastlinojedcev ali \u017eu\u017eelk, z zaznavanjem elektromagnetnih povratnih informacij. Pohvale ekipi za odkritje molekularne osnove biomagnetizma v rastlinah.<\/p>\n\n\n\n
