As a result of global warming and climate change, the number and intensity of weather events such as droughts, heat waves, and floods are increasing, resulting in major losses in crop yield worldwide. Combined with the accumulation of diffe...

All land plants modulate their growth and physiology through intricate signaling cascades. The majority of these are at least modulated-and often triggered-by phytohormones. Over the past decade, it has become apparent that some phytohormon...
Arsenic redox transformations and cycling in the rhizosphere of Pteris vittata and Pteris quadriaurita [0.03%]
蜈蚣草和拟芒萁根际砷的氧化还原转化及循环机制研究
Stefan Wagner,Christoph Hoefer,Markus Puschenreiter et al.
Stefan Wagner et al.
Pteris vittata (PV) and Pteris quadriaurita (PQ) are reported to hyperaccumulate arsenic (As) when grown in Asrich soil. Yet, little is known about the impact of their unique As accumulation mechanisms on As transformations and cycling at t...
Volatile organic compound emission in tundra shrubs - Dependence on species characteristics and the near-surface environment [0.03%]
苔原灌木的挥发性有机化合物排放量取决于物种特征和近地表环境的因素

Temperature is one of the key abiotic factors during the life of plants, especially in the Arctic region which is currently experiencing rapid climate change. We evaluated plant traits and environmental variables determining leaf temperatur...
Optimization of potassium for proper growth and physiological response of Houttuynia cordata Thunb [0.03%]
适宜的钾素对鱼腥草(Houttuynia cordata)生长和生理反应的重要性
Y Wen Xu,Yu Ting Zou,Amjad M Husaini et al.
Y Wen Xu et al.
Houttuynia cordata Thunb. is an edible herb with a variety of pharmacological activities, but only limited information is available about its response towards potassium supplementation. Sterile plantlets were cultured in media with differen...

Ifigenia Urbina et al.
Diverse plant functions (e.g. growth, storage, defense and anti-stress mechanisms) use elements disproportionally. We hypothesized that plants growing under different abiotic and biotic conditions would shift their elemental compositions in...
Temporal regulation of terpene synthase gene expression in Eucalyptus globulus leaves upon ozone and wounding stresses: relationships with stomatal ozone uptake and emission responses [0.03%]
桉叶球兰萜类合成酶基因的时空表达模式及其与叶片臭氧交换的关系研究
Arooran Kanagendran,Leila Pazouki,Rudolf Bichele et al.
Arooran Kanagendran et al.
Ozone and wounding are key abiotic factors but, their interactive effects on temporal changes in terpene synthase gene expression and emission responses are poorly understood. Here, we applied combined acute ozone and wounding stresses to t...
Reactive oxygen species, oxidative signaling and the regulation of photosynthesis [0.03%]

Reduction-oxidation (redox) reactions, in which electrons move from a donor to an acceptor, are the functional heart of photosynthesis. It is not surprising therefore that reactive oxygen species (ROS) are generated in abundance by photosyn...
Elemental distribution in developing rice grains and the effect of flag-leaf arsenate exposure [0.03%]
砷酸盐暴露对水稻生长发育期籽粒中元素分布的影响

We measured the bulk grain concentrations of arsenic (As), along with rubidium (Rb) and strontium (Sr) as indicators of phloem and xylem transport respectively, in rice (Oryza sativa cv. Italica Carolina) pulsed with arsenate at two exposur...
Differential regulation of volatile emission from Eucalyptus globulus leaves upon single and combined ozone and wounding treatments through recovery and relationships with ozone uptake [0.03%]
单一和复合型臭氧和伤口处理对尤加利树叶的挥发排放的不同调节及其与臭氧吸收的关系

Arooran Kanagendran
Both ozone and wounding constitute two key abiotic stress factors, but their interactive effects on plant constitutive and stress-elicited volatile (VOC) emissions are poorly understood. Furthermore, the information on time-dependent modifi...
