The fern tur Asplenium hibridizatsiya qobiliyati bilan, ayniqsa mo''tadil zonalarda yaxshi ma'lum.
Appalachi Asplenium gibrid kompleks
The Appalachi gibrid kompleks Asplenium a poliploid kompleksi 3 diploid turidan, hibridlanish va xromosomaning avvalgisidan ikki baravar ko'payishidan hosil bo'lgan 3 allotetraploid turidan va 6 tur orasida turli xil diploid, triploid va tetraploid duragaylaridan tashkil topgan.
Uchta diploid ota-ona turlari tog 'taloqlari (Asplenium montanum ), ebony spleenwort (Asplenium platyneuron ) va Amerika yuradigan fern (Asplenium rhizophyllum ). Ularning xromosoma qo'shimchalari mos ravishda qisqartirilgan "MM", "PP" va "RR". Gibridlanishidan uchta mumkin steril diploid duragaylar paydo bo'lishi mumkin:
- A. montanum × platineyron (MP) juda kam hollarda to'plangan.
- A. montanum × rhizophyllum (MR) mavjud bo'lish nazariyasiga ega, ammo hech qachon yig'ilmagan.
- A. platyneuron × rhizophyllum (PR) Skottning spleenwort nomi bilan tanilgan (Asplenium × ebenoidlar ) va nisbatan keng tarqalgan.
Bunga qo'chimcha, A. platineyron va A. rizofillum, yanada keng diapazonga ega bo'lgan, Appalachian majmuasi tashqarisida boshqa taloq turlari bilan duragaylashadi.
O'tmishda biron bir vaqtda steril diploid duragaylarining har biri xromosomalarning ikki barobar ko'payish hodisasini boshdan kechirdi, bu ularni serhosil allotetraploidlarga aylantirdi; allozim tahlil shuni ko'rsatadiki, bu bir necha mustaqil holatlarda sodir bo'lgan A. montanum × platineyron va A. montanum × rhizophyllum. Ushbu ikki baravar ko'paygan hodisalar quyidagi tetraploidlarni keltirib chiqardi:
| Umumiy ism | Ilmiy nomi | Ota-onalar | Xromosomalar | Izohlar / tarqatish |
|---|---|---|---|---|
| Bredlining taloqlari | Asplenium bradleyi | A. montanum × platineyron | MMPP | Appalachilar, Ozarklar va Ouachita tog'lari. |
| Lobed spleenwort | Asplenium pinnatifidum | A. montanum × rhizophyllum | MMRR | Appalachilar va Shouni Xillz. |
| Tutviler taloq | Asplenium tutwilerae | A. platyneuron × rhizophyllum | PPRR | Gavana Glen, Alabama |
Ushbu allotetraploidlar serhosil bo'lganligi sababli, ular bir-biri bilan va uchta diploid turlari bilan kesib o'tib quyidagi steril triploid va tetraploid duragaylarini hosil qilish imkoniyatiga ega, ularning aksariyati juda kam uchraydi va vaqti-vaqti bilan ota-onalarining diapazonlari bir-biriga to'g'ri keladigan joyda paydo bo'ladi:
| Umumiy ism | Ilmiy nomi | Ota-onalar | Xromosomalar | Ploidy | Izohlar / tarqatish |
|---|---|---|---|---|---|
| Wherry's Spleenwort | Asplenium × wherryi | A. bradleyi × montanum | MMP | triploid | |
| A. bradleyi × platineyron | MPP | triploid | Dastlabki marta bir marta to'planganiga ishonishdi Pensilvaniya; sayt endi yo'q qilindi. Shuningdek xabar berilgan Sequatchi County, Tennessee. | ||
| Graves 'spleenwort | Asplenium × gravesii | A. bradleyi × pinnatifidum | MMPR | tetraploid | |
| Trudellning taloqlari | Asplenium × trudellii | A. pinnatifidum × montanum | MMR | triploid | Appalachilar va Shouni Xillz. |
| Kentukki spleenwort | Asplenium × kentuckiense | A. pinnatifidum × platineyron | MPR | triploid | |
| A. tutwilerae × pinnatifidum | MPRR | tetraploid | Madaniyatda yaratilgan. | ||
| Boydstonning taloqi | Asplenium × boydstoniae | A. tutwilerae × platineyron | PPR | triploid | Gavana Glen, Alabama |
| A. tutwilerae × rhizophyllum | PRR | triploid | Madaniyatda tasodifan yaratilgan. |
