Enhanced Leaf Cooling Is a Pathway to Heat Tolerance in Common Bean [PDF]

Frontiers in Plant Science, 2020
Common bean is the most consumed legume in the world and an important source of protein in Latin America, Eastern, and Southern Africa. It is grown in a variety of environments with mean air temperatures of between 14°C and 35°C and is more sensitive to ...

Water Use, Leaf Cooling and Carbon Assimilation Efficiency of Heat Resistant Common Beans Evaluated in Western Amazonia [PDF]

Frontiers in Plant Science, 2021
In our study, we analyzed 30years of climatological data revealing the bean production risks for Western Amazonia. Climatological profiling showed high daytime and nighttime temperatures combined with high relative humidity and low vapor pressure deficit.

Transpirational Leaf Cooling Effect Did Not Contribute Equally to Biomass Retention in Wheat Genotypes under High Temperature [PDF]

Plants, 2022
High temperature and water deficit are the most critical yield-limiting environmental factors for wheat in rainfed environments. It is important to understand the heat avoidance mechanisms and their associations with leaf morpho-physiological traits that

Insect herbivory antagonizes leaf cooling responses to elevated temperature in tomato. [PDF]

Proc Natl Acad Sci U S A, 2020
Significance Crop damage by insect pests is predicted to increase as rising surface temperatures accelerate insect metabolism, population size, and range expansion. The plant defense hormone jasmonate promotes resistance to diverse herbivores, but how this wound signal impacts the plant’s ability to cope with a combination of herbivory and ...

Intensive leaf cooling promotes tree survival during a record heatwave. [PDF]

Proc Natl Acad Sci U S A
Increasing heatwaves are threatening forest ecosystems globally. Leaf thermal regulation and tolerance are important for plant survival during heatwaves, though the interaction between these processes and water availability is unclear.

Bionic optimization for cooling structure of GaN HEMTs inspired by leaf vein structure

Case Studies in Thermal Engineering, 2023
Inspired by the leaf vein structure, this article proposes cooling structures with tapered contracting manifold and leaf vein feature, to optimize the cold plate structure for high heat flux gallium nitride high electron mobility transistors (GaN HEMTs).

Absorption of Energy in Excess, Photoinhibition, Transpiration, and Foliar Heat Emission Feedback Loops During Global Warming [PDF]

Cells
Global warming is increasingly constraining plant productivity by altering the photosynthetic energy balance and leaf thermoregulation. Under high light and elevated temperatures, absorption of energy in excess (AEE) by photosystem II disrupts ...

Arboreal Urban Cooling Is Driven by Leaf Area Index, Leaf Boundary Layer Resistance, and Dry Leaf Mass per Leaf Area: Evidence from a System Dynamics Model

Atmosphere, 2023
Heat waves are becoming more frequent due to climate change. Summer heat waves can be particularly deadly in cities, where temperatures are already inflated by abundant impervious, dark surfaces (i.e., the heat island effect).

Adaptation of Interspecific Mesoamerican Common Bean Lines to Acid Soils and High Temperature in the Amazon Region of Colombia

Plants, 2021
Knowledge of the physiological basis for improved genetic adaptation of common bean (Phaseolus vulgaris L.) lines to acid soils and high temperature conditions in the Amazon region of Colombia is limited. In this study, we evaluated the differences among

Tree Traits and Microclimatic Conditions Determine Cooling Benefits of Urban Trees

Atmosphere, 2023
Trees play a key role in mitigating urban heat by cooling the local environment. This study evaluated the extent to which street trees can reduce sub-canopy air temperature relative to ambient conditions (ΔT), and how ΔT relates to tree traits and ...
