Plants respond to high ambient temperature with altered developmental and growth programs, termed thermomorphogenesis. Here we show that thermomorphogenesis is conserved in Arabidopsis, soybean, and rice and that it is linked to a decrease in the levels of the two macronutrients nitrogen and phosphorus...

Within stands, seasonal patterns of fine-root respiration rates followed temporal changes in soil temperature, ranging from a low of 2.1 μmol O2 kg−1 s−1 at 6 °C to a high of 7.0 μmol O2 kg−1 s−1 at 18 °C. Differences in respiration rates among stands at a given ...
It is proposed that these and related mechanosensitive channels may participate in a variety of responses to temperature, including thermonasty, thermotropism, hydrotropism, and both cold damage and cold acclimation... Jiu,Ping,Ding,... - 《Plant Journal》 被引量: 365发表: 1993年 From the Cove...
response to high shoot/root temperature during the early growth stages is important for successful production in tropical and subtropical environments. This study examined the physiological response of wheat cultivars to high shoot and/or root temperatures during early growth stages. Three cultivars; ...
The response of single-leaf photosynthetic rate to temperature may be different from the response of canopy photosynthetic rate to temperature. This study ... M Tollenaar - 《Crop Science》 被引量: 320发表: 1989年 Low temperature stress in maize (Zea mays L.) induces genes involved in photos...
plant response as changes in measured parameters (leaf temperature, g s and ABA) occur in the shoot, but the response is solely due to detection of very high CO 2 concentration at the root/soil interface which results in loss of stomatal regulation and disruption to control over water uptake...
However, treatments that caused the lowest activities resulted in the fastest, but briefest, linear rates of grain . We concluded that shoots and roots interact in the response of to high temperature, and that stress on both organs affects accumulation of in grain. 展开 ...
It is likely that stomatal closure at high temperature is also a response to enhanced levels of intracellular CO2 as cell respiration rises (see p. 201). The evolution of these two patterns of response, to light and CO2, has acted to facilitate the supply of CO2 to the photosynthetic ...
(3) The effect of N addition on temperature sensitivity of root respiration was also varied due to N addition rate. (4) N and carbon/nitrogen ratio were the main driving factors of root respiration of P. tabulaeformis, while chemical properties had a slight driving effect on root respiration...
