The roles of cell wall invertase inhibitor in regulating chilling tolerance in tomato

BMC Plant Biology, 2017
Background Hexoses are important metabolic signals that respond to abiotic and biotic stresses. Cold stress adversely affects plant growth and development, limiting productivity. The mechanism by which sugars regulate plant cold tolerance remains elusive.

CRISPR/Cas9-mediated mutation in auxin efflux carrier OsPIN9 confers chilling tolerance by modulating reactive oxygen species homeostasis in rice

Frontiers in Plant Science, 2022
Phytohormone auxin plays a vital role in plant development and responses to environmental stresses. The spatial and temporal distribution of auxin mainly relies on the polar distribution of the PIN-FORMED (PIN) auxin efflux carriers.

Deep-sequencing transcriptome analysis of chilling tolerance mechanisms of a subnival alpine plant, Chorispora bungeana

BMC Plant Biology, 2012
Background The plant tolerance mechanisms to low temperature have been studied extensively in the model plant Arabidopsis at the transcriptional level. However, few studies were carried out in plants with strong inherited cold tolerance.

Is an Apple an Orange? A Large Language Model Benchmark for Candidate Term Extraction and Subclass Decisions Against Upper Ontologies in Engineering and Materials Science

Advanced Engineering Materials, EarlyView.
Building machine‐readable vocabularies for materials science is slow, expert‐driven work. This study benchmarks 13 large language models on two of its first steps: finding candidate terms in engineering articles and deciding where they belong in a class hierarchy.

Chilling Tolerance Improving of Watermelon Seedling by Salicylic Acid Seed and Foliar Application

Notulae Scientia Biologicae, 2013
Chilling temperatures lead to numerous physiological disturbances in the cells of chilling-sensitive plants and result in chilling injury and death of tropical and subtropical plants such as watermelon.

Gating of aquaporins by low temperature in roots of chilling-sensitive cucumber and chilling-tolerant figleaf gourd [PDF]

Journal of Experimental Botany, 2005
Effects of low temperature (8 degrees C) on the hydraulic conductivity of young roots of a chilling-sensitive (cucumber, Cucumis sativus L.) and a chilling-resistant (figleaf gourd, Cucurbita ficifolia Bouche) crop have been measured at the levels of whole root systems (root hydraulic conductivity, Lp(r)) and of individual cortical cells (cell ...

Inverse Identification of Energy‐Dependent Laser Absorptivity in NiTi Laser Powder‐Bed Fusion via Calibrated Melt Pool Simulation

Advanced Engineering Materials, EarlyView.
A combined experimental–computational framework identifies energy‐dependent laser absorptivity for NiTi in laser powder‐bed fusion, applicable to conduction and transition modes. Single‐track experiments and thermofluid smoothed particle hydrodynamics simulations are coupled through inverse analysis of melt pool geometry.

Abscisic acid participates in melatonin-induced chilling tolerance of cucumber via regulating photosynthesis and the antioxidant system

Vegetable Research
Melatonin (MT) and abscisic acid (ABA) are crucial in regulating abiotic stress tolerance in cucumber. However, their roles as signaling molecules in regulating chilling tolerance remain ambiguous.

Seedling Growth and Chilling Stress Effects on Photosynthesis in Chilling-Sensitive and Chilling-Tolerant Cultivars of Zea mays

Journal of Plant Physiology, 1991
Summary Distinct differences were observed between chilling-sensitive (CS) and chilling-tolerant (CT) maize cultivars with respect to early seedling growth strategies and response to chilling at 5 °C. The CT cultivar exhibited more rapid emergence and growth rates and an earlier depletion of seed reserves.

Boron Nutrition and Chilling Tolerance of Warm Climate Crop Species [PDF]

Annals of Botany, 2005
Field observations and glasshouse studies have suggested links between boron (B)-deficiency and leaf damage induced by low temperature in crop plants, but causal relationships between these two stresses at physiological, biochemical and molecular levels have yet to be explored.
