ملخص المقالة :
سلول‌‌های گیاهی جهت درک سیگنال‌‌های مختلف پیرامون شان نمو یافته‌‌اند و از طریق تعدیل بیان ژن‌‌ها به آن‌‌ها پاسخ می‌‌دهند. خشکی یک ویژگی آب و هوایی طبیعی و محدود کننده عملکرد گیاهان زراعی است. در این پژوهش به منظور ارزیابی واکنش گیاه سرخارگل به تنش خشکی، در یک آزمایش گلدانی، پس از اعمال سطح تنش خشکی شامل آبیاری به میزان 25، 50، 75 و 85% ظرفیت زراعی همراه با آبیاری معمول، میزان پرولین، پتاسیم، فسفر و نیتروژن برگ اندازه گیری و نیز بیان پروتئین های شوک حرارتی با استفاده از روش Real- Time PCR در بافت برگ مورد ارزیابی قرار گرفت. افزایش معنی‌دار میزان پرولین، کاهش پتاسیم، فسفر و نیتروژن در بافت برگ در اثر اعمال تنش خشکی مشاهده شد. همچنین اعمال تنش خشکی موجب افزایش بیان پروتئین شوک حرارتی در تمامی سطوح تنش مورد مطالعه شد. به طور کلی، گیاه سرخارگل با به کارگیری برخی سازوکارهای دفاعی از قبیل افزایش محتوی پرولین و پروتئین شوک حرارتی در مقابل تنش خشکی مقاومت می کند.
