Photosynthetica, 2019 In dryland regions, soil moisture stress often leads to desiccation and causes injury to photosynthetic machinery. Recently, chlorophyll fluorescence (ChlF)-based assessment of photosynthetic efficiency under drought stress is gaining attention due to ...

Self-organized criticality, evolution and the fossil extinction record [PDF]
Proc. R. Soc. London B 263, 1605 (1996), 1996 Statistical analysis indicates that the fossil extinction record is compatible with a distribution of extinction events whose frequency is related to their size by a power law with an exponent close to two. This result is in agreement with predictions based on self-organized critical models of extinction, and might well be taken as evidence of critical

Microtubules, signalling and abiotic stress [PDF]
The Plant Journal, 2013 SummaryPlant microtubules, in addition to their role in cell division and axial cell expansion, convey a sensory function that is relevant for the perception of mechanical membrane stress and its derivatives, such as osmotic or cold stress. During development, sensory microtubules participate in the mechanical integration of plant architecture ...

Environmental Progress &Sustainable Energy, Volume 42, Issue 1, January/February 2023., 2023 Abstract Vegetation has successfully been used for cleaning up metal(loid) polluted water bodies and lands through extracting and accumulating of contaminants in their aboveground biomass (phytoextraction). As this remediation technique is approaching extensive demonstration scale application and potential commercialisation, research efforts have been ...

Genetic diversity of barley accessions and their response under abiotic stresses using different approaches [PDF]
In this investigation, five separate experiments were carried out. The first experiments were examined the molecular characteristics of 59 barley accessions collected from different regions in Iraq using three different molecular markers (ISSR, CDDP, and Scot).

Sediment supply control on morphodynamic processes in gravel‐bed river widenings
Earth Surface Processes and Landforms, Volume 47, Issue 15, Page 3415-3434, December 2022., 2022 Mobile‐bed laboratory experiments combined with two‐dimensional hydrodynamic numerical simulations showed that sediment supply is a key driver of morphodynamic activity in reach‐scale dynamic river widenings. Sediment supply roughly balanced with the channel's transport capacity led to active channel widening and continued patchy sediment relocation ...
