تنش مهم زیست محیطی موثر بر عملکرد گیاه و توزیع است. انطباق با LT یک پدیده واکنش استرس زا بسیار پویا است و شامل
پیچیده مکالمه متقابل بین سطوح نظارتی متفاوت است. اگر چه گیاهان در حساسیت خود را
به LT متفاوت است،

رشد و تولید گیاه تاثیر معکوسی دارند و باعث مجموعه ای از تغییرات مورفولوژیکی،
فیزیولوژیکی، بیوشیمیایی و مولکولی در گیاهان می شود. دماهای پائین(Lt) به عنوان
دماهای سردکننده تابع صفر تعریف شدند که در طبیعت متداول هستند و بر عملکرد گیاه
بویژه در آب و هواهای سرد در ارتفاع و عرض های جغرافیایی محدودیت محیطی عمده ای
ایجاد میب کنند. LT ممکن است در گیاهان در دو روش باعث ایجاد فشار شود:
1 - فقط بوسیله اثرات LT و 2 . بوسیله هیدروژن زدایی سلول
ها و بافت ها در هنگامی که آب سلولی انجماد می شود. مقاومت به دمای پایین یک ویژگی
چندژنی دربرگیرنده تعداد زیادی از ژن های القائی دمای پائین می باشد. این ژن ها
عمدتاً سه نوع پروتئین را رمزگذاری می کنند: پروتئین های ساختاری، پروتئین های
تنظیمی(مانند فاکتورهای رونویسی، فاکتورهای طولانی شدن فرایند ترجمه و پروتئین های
جابجائی سیگنال) و اسموپروتکتانت ها مانند دی هیدرین ها و پروتئین های فراوان

فشار دمای پائین یک فرایند پویا است که به فاکتورهای مختلفی بستگی دارد(از جمله
مرحله رشد، مدت و شدت فشار، میزان سرد شدن و گرم شدن مجدد و اینکه تشکیل یخ به طور
درون سلولی یا بیرون سلولی در فضاهای میان سلولی رخ دهد). در طی آغاز فشار

Genetic engineering for heat tolerance in plants ...
High temperature tolerance has been genetically engineered in plants mainly by over-expressing the heat shock protein genes or indirectly by altering levels of heat shock transcription factor proteins. Apart from heat shock proteins, thermotolerance has also been altered by elevating levels of osmolytes, increasing levels of cell detoxification enzymes and through altering membrane fluidity.

Plant responses to environmental stresses—from …
Plant survival under low temperature depends on the physiological and molecular responses triggered by the plant on exposure to low temperature (Sergeant et al. 2014; John et al. 2016). These can be confounded by photoperiod response as cold is often associated with extreme latitudes.

Low-temperature (LT) tolerance in cereals is dependent upon a highly integrated system of structural, regulatory, and developmental genes. In regions with cold winters, vernalization requirement is an important adaptive feature that delays heading by postponing the transition from the vegetative to the reproductive phase.
