Special Issue Information

Dear Colleagues,

Plant respiration shares many aspects of aerobic metabolism with other multicellular organisms. Plant respiration has been studied for more than a century. Nevertheless, there are so many aspects of this complex process, which we still need to study further in order to enhance our understanding.

One the one hand, plant respiration may contribute up to two thirds of the entire CO2-release at an ecosystem level and thus ca. 60 Gt C to the atmosphere annually. Therefore, accurate modelling of plant respiration is needed for both crop growth models and for modelling the biosphere’s interaction with global climate change. Much exciting research is still emerging on this topic, including modelling exercises and experimental studies ranging from the ecosystem to the organelle. We still do not fully agree on (or understand) exactly how the rate of respiration is governed by both abiotic factors, such as water, light, and temperature at, e.g., different organ levels. Nor do we fully understand exactly how the rate of respiration may be governed by biotic factors, such as substrate supply, infections, competition, and the use of respiratory products.

One the other hand, plant respiration provides the cells with the energy (ATP), reducing equivalents (NADH) and C-skeletons for maintenance, growth, and nutrient uptake. Therefore, we need to better understand how the circadian rhythm in cellular activity that is regulated by a molecular clock interacts with the rate of plant respiration.

Therefore, in this Special Issue articles (original research papers, perspectives, hypotheses, opinions, reviews, and modeling approaches and methods) that focus on the control of plant respiration and the effects of plant respiration at all spatial and temporal scales are welcome.

Alternative Pathway is Involved in Nitric Oxide-Enhanced Tolerance to Cadmium Stress in Barley Roots

Alternative pathway (AP) has been widely accepted to be involved in enhancing tolerance to various environmental stresses. In this study, the role of AP in response to cadmium (Cd) stress in two barley varieties, highland barley (Kunlun14) and barley (Ganpi6), was investigated. Results showed that the malondialdehyde (MDA) content and electrolyte leakage (EL) level under Cd stress increased in two barley varieties. The expressions of alternative oxidase (AOX) genes (mainly AOX1a), AP capacity (Valt), and AOX protein amount were clearly induced more in Kunlun14 under Cd stress, and these parameters were further enhanced by applying sodium nitroprussid (SNP, a NO donor). Moreover, H2O2 and O2- contents were raised in the Cd-treated roots of two barley varieties, but they were markedly relieved by exogenous SNP. However, this mitigating effect was aggravated by salicylhydroxamic acid (SHAM, an AOX inhibitor), suggesting that AP contributes to NO-enhanced Cd stress tolerance. Further study demonstrated that the effect of SHAM application on reactive oxygen species (ROS)-related scavenging enzymes and antioxidants was minimal. These observations showed that AP exerts an indispensable function in NO-enhanced Cd stress tolerance in two barley varieties. AP was mainly responsible for regulating the ROS accumulation to maintain the homeostasis of redox state. Full article
