Several plant responses to light conditions are modulated directly by hormones or by hormonally regulated metabolic changes; the relationship between light perception and hormonal regulation has been well established for many processes. In addition, new information should stimulate development of crop ...
Light addition, but not nitrogen enrichment, accelerated directional plant community responses to warming, increasing the dominance of warmth-preferring taxa over cold-tolerant plants (a process described as thermophilization6,10,11,12). Tall, competitive plants took greatest advantage of the ...
原文定位:第2段第5行:The seasonal impact of day length on physiological responses is called photoperiodism.(白天的时长对生理反应的季节性影响被称为光周期现象)第2段倒数第5行:Other examples of photoperiodism occurs in plants.(在植物中也有光周期现象),由此可知光周期的产生与时长和植物有关,并未提到地...
近日,美国密苏里大学(University of Missouri)的Ron Mittler团队在Plant Physiology在线发表了一篇题为题为Phytochrome B is required for systemic stomatal responses and ROS signaling during light stress 的研究论文,揭示了拟南芥PhyB在光胁迫诱导的系统性气孔开闭及活性氧信号调控中的作用。 该研究发现,白光胁迫可以...

There is a wide range of photosynthetic responses of plants to variations in light intensity. Some plants reach maximal photosynthesis at one-quarter full sunlight, and others, like sugarcane, never reach a maximum, but continue to increase photosynthesis rate as light intensity rises. Plants in ...

If the plant receives too little or too much light, it leads to problems such as light stress. Light stress in plants is a condition where plants are exposed to light levels either too high or too low for their healthy growth and development. Stress leads to reduced growth, discoloration, ...
There is another source of variation among experiments that is often not taken into account when comparing data. Using the example of light again, two experiments may show different phenotypic responses to light intensity (e.g. a strong positive effect vs. no effect, Fig.1a). Where plant biol...
The blue light component of canopy shade is critical for phototropism in green seedlings. 进一步研究发现, cry1突变体增强的向光性反应取决于光敏色素相互作用因子PIF4和PIF5。在有利的光照条件下,cry1会限制PIF4的表达,而在低蓝光条件下,PIF4的表达会增加,从而促进向光性反应,这意味着cry1至少部分地通过控...
