Abstract
Oʻsimlik organlarining gravitatsiya vektoriga nisbatan yoʻnaltirilgan oʻsishi - gravitropizm - ildiz tizimi arxitekturasi, suv va mineral moddalarni oʻzlashtirish hamda noqulay muhit sharoitlariga moslashishda muhim ahamiyatga ega. Maqolada 2001– 2026-yillarda chop etilgan ilmiy manbalar asosida gravitropik signalni qabul qilish va uzatishning zamonaviy statolit–LAZY-RLD-PIN modeli tahlil qilindi hamda triterpenoid birikmalarning ushbu tizimga taʼsir koʻrsatish imkoniyatlari baholandi. Amiloplast- statolitlarning choʻkishi LAZY oqsillarini hujayraning pastki tomoniga qutblashi, LAZY esa RLD oqsillarini jalb qilib, PIN tashuvchilari orqali auksinning assimetrik taqsimlanishiga olib kelishi koʻrsatildi. Triterpenoid saponin - chromosaponin I ning AUX1 auksin tashuvchisi orqali ildiz gravitropizmini oʻzgartirishi triterpenoidlar va gravitropik signal tizimi oʻrtasidagi bogʻliqlikning bevosita eksperimental dalili ekani qayd etildi. Glitsirrizin kislota va uning fitogormonlar bilan supramolekulyar komplekslarining ildiz oʻsishiga taʼsiri maʼlum boʻlsa-da, ularning LAZY-RLD-PIN yoʻliga bevosita taʼsiri hali isbotlanmagan. Ushbu gipotezani tekshirish uchun ehtimoliy taʼsir nuqtalari va ularni oʻrganish usullari taklif etildi.References
