The occurrence of heat-shock proteins (HSPs) in response to high temperature stress is a universal phenomenon in higher plants and has been well documented. However, in agriculturally important species, less is known about the expression of HSPs under natural environments. A review of the heat-shock response in wheat (Triticum aestivum L.) is presented and recent results on the expression of wheat HSPs under diurnal stress and field conditions are reported. In the field experiment, flag leaf blade temperatures were obtained and leaf blades collected for northern blot analysis using HSP 16.9 cDNA as a probe. Temperatures of leaf blades ranged from 32 to 35�C under the tested field conditions at New Deal near Lubbock, Texas. Messenger RNAs encoding a major class of low molecular weight HSPs, HSP 16.9, were detected in all wheat genotypes examined. The results suggested that HSPs are synthesised in response to heat stress under agricultural production, and furthermore, that HSPs are produced in wheats differing in geographic background. In the controlled growth chamber experiment, HSP expression in two wheat cultivars, Mustang (heat tolerant) and Sturdy (heat susceptible) were analysed to determine if wheat genotypes differing in heat tolerance differ in in vitro HSP synthesis (translatable HSP mRNAs) under a chronic, diurnal heat-stress regime. Leaf tissues were collected from seedlings over a time-course and poly (A)+RNAs were isolated for in vitro translation and 2-D gel electrophoresis. The protein profiles shown in the 2-D gel analysis revealed that there were not only quantitative differences of individual HSPs between these two wheat lines, but also some unique HSPs which were only found in the heat tolerant line. This data provides evidence of a correlation between HSP synthesis and heat tolerance in wheat under a simulated field environment and suggests that further genetic analysis of HSPs in a segregating population is worthy of investigation. In conclusion, the results of this study provide an impetus for the investigation of the roles of HSP genes in heat tolerance in wheat.

Пшеница одна из сельскохозяйственных культур, которая подвергается действию температурного стресса в течение онтогенеза и особенно чувствительна к действию стресса на начальных стадиях её развития. Высокие температуры ограничивают рост, развитие и продуктивность растений. Однако, растения могут адаптироваться к температурному стрессу и имеют адаптивные механизмы на клеточном и молекулярном уровнях. Одним из таких адаптивных механизмов является увеличение синтеза белков теплового шока (БТШ), функции которых очень важны и разнообразны.Целью данной работы было изучить влияние различных тепловых обработок (37 и 39 ºC в течение 1, 3, 6, 24 ч и 50 ºC в течение 1, 3, 5 ч) на теплоустойчивость проростков яровой пшеницы (Triticum aestivum L.) и синтез БТШ (101, 70, 60 и 16.9 кДа) в побегах 4-х суточных и листьях 8-ми суточных проростков.На основании полученных данных сделан вывод, что 4-х суточные и 8-ми суточные проростки яровой пшеницы характеризуются схожей реакцией на тепловой стресс при 50 ºC, однако 4-х суточные проростки более устойчивы в начальный период стрессового воздействия. Воздействие температурами 37 и 39 ºC подходят для адаптации яровой пшеницы на начальных стадиях её развития (4-х суточные и 8-ми суточные проростки). Эти температуры приводят к схожей тенденции в синтезе БТШ в побегах и листьях. В тоже время, содержание БТШ16.9 зависит от стадии развития пшеницы. В нормальных условиях был отмечен синтез БТШ16.9 в побегах, но не в листьях. Сделано заключение, что адаптация 8-ми суточных проростков более длительный процесс (6-24 ч воздействия 37 и 39 ºC) по сравнению с 4-х суточными проростками (3-6 ч воздействия 37 и 39 ºC).
