What function does NADPH serve in photosynthesis?

Root properties impact strongly on plant performance, but high-throughput methods for non-invasive and quantitative root trait assessment are rarely available. We developed and tested a root phenotyping concept, which involves NIR imaging of roots grown along surfaces of transparent culture vessels using visible light blocking long pass filters. We reveal the viability of the concept and its suitability for simultaneous root and shoot phenotyping.

Peroxisomes balance the cellular levels of reactive oxygen species (ROS) and therefore should modulate ROS-regulated programs like autophagy or cell death. We used tobacco suspension cultures to show that degradation of peroxisomes via autophagy was a prerequisite for cell death and depended on the levels of the major peroxisomal protein, catalase. This suggests a role of plant catalase in the regulation of peroxisome turnover and autophagic cell death.

Chilling stress limits the productivity and geographical distribution of many plants throughout the world. Accumulation of the endoplasmic reticulum-located small heat shock protein HSP22.5 enhanced photochemical activity and oxidation resistance and alleviated endoplasmic reticulum stress caused by chilling stress in transgenic tobacco plants. HSP22.5 could be useful for improving the tolerance of chilling-sensitive plant types.

Plants adapt to environmental light conditions with the use of the sophisticated phytochrome system. In this work, polymorphism of its major component – phytochrome A– was investigated. With the use of transgenic and fluorescence technique, it was shown that two molecular types of the photoreceptor differ by the state of phosphorylation and their existence accounts for its complex functions.

Photosynthetic electron transport chain is not the only source of ATP and NADPH for photosynthesis; it is a sensor, informing adaptation systems of plant about environmental changes. An important transmitter of this information is hydrogen peroxide whose mechanisms of formation are presented, laying special emphasis on the formation outside and within thylakoid membrane. It is discussed, that the formation place can ensure definite signal about the specific environmental change.

Leaf carbon isotope composition (δ13C) has been used to screen for water-use efficiency in C3 plants, but gaps in the understanding of factors influencing δ13C have limited its application in C4 species. This study exploited maize genetic diversity to explore biochemical and post-photosynthetic factors that may influence δ13C. Our findings indicate that the observed variation in leaf carbon isotope composition across diverse maize lines is likely driven by differences in stomatal and mesophyll conductance and not photosynthetic or respiratory metabolism.

Melatonin is an important hormone and signalling molecule in all forms of life including humans, plants and bacteria. Recent plant physiology and genomic experiments have described the redirection of plant growth and metabolism, and demonstrated a diversity of genes involved in response to melatonin, however, the exact metabolic cascades that translate melatonin signals into physiological responses is not fully understood. This review provides an overview of melatonin mediated signalling manifested as behaviours and its roles in basic and industrial research.

The inflated leaf petiole of undergoes a developmental process from solid to hollow phase. Schizo-lysigenous aerenchyma was developed via the mechanism of programmed cell death (PCD) during the process of inflated leaf petiole morphogenesis. Thus, a trans-disciplinary systems approach that recognizes the need for integration of cytological and molecular characteristics for identification of aerenchyma type in aquatic plant is required.
