Adaptation to ionizing radiation of higher plants: From …
Plant irradiation increases the level of the most ROS. As previously mentioned, one of the products of radiolysis of H 2 O is • OH. • OH has a very short duration but is extremely reactive and responsible for numerous types of cell damage resulting in apoptosis (Fig. 1).Another ROS, including H 2 O 2, is generated by secondary …
Adaptation and coordinated evolution of plant hydraulic traits
To fill this gap, we compiled a global dataset of hydraulic traits describing xylem conductivity (K s), xylem resistance to embolism (P50), sapwood allocation relative to leaf area (Hv) and drought exposure (ψ min), and matched it with global seed plant phylogenies. Individually, these traits present medium to high levels of phylogenetic ...
Cytokinins: metabolism and function in plant adaptation to
Cytokinins (CKs) regulate plant adaptation to stress. Members of the CK family of plant hormones are considered to be master regulators, strongly influencing plant growth and development. In the past 10 years, CK metabolism and signaling pathways have become a major focus in plant biology research 1, 2, 3.

Plant Adaptations: Introduction and Ecological Classification of Plants
Amphibious plants grow either in shallow water or on the muddy substratum^ Amphibious plants which grow in saline marshy places are termed as 'halophytes. Roots and some parts of stems and leaves in these plants may be submerged in water or buried m mud but some foliage, branches and flowering shoots spring well above the surface of water or ...

What Is decapitation in Plants?
Q. Decapitation i.e. removal of shoot tips in a plant usually results in. Q. In decapitated plants, axillary buds are activated because. Q. Assertion (A): Decapitation of shoot tip in plants induces the growth of their lateral buds. Reason (R): Accumulation of auxins in lateral buds causes inhibition of their growth. Q.
Adaptation to ionizing radiation of higher plants: From …
Plants DSBs repair mechanisms mainly involve homologous and non-homologous dependent systems, the latter especially causing a loss of genetic information. Repeated ionizing radiation (acute or chronic) ensures that plants adapt, demonstrating radioresistance. An adaptive response has been suggested for this phenomenon.

Comparative Genomics of NAC Transcriptional Factors in
NAC proteins constitute one of the largest groups of plant-specific transcription factors and are known to play essential roles in various developmental processes. They are also important in plant responses to stresses such as drought, soil salinity, cold, and heat, which adversely affect growth. The current knowledge regarding …

Plants are the primary producers in most terrestrial ecosystems and form the basis of the food web in those ecosystems. [82] Plants form about 80% of the world biomass at about 450 gigatonnes (4.4 × 10 11 long tons; 5.0 × 10 11 short tons) of carbon. [83]

Plant responses and adaptations to a changing climate
Indeed, the physiological responses of plants to elevated CO2 in the 21st century are not likely to offset the negative consequences of surface drying (Dai et al., 2018). A meta-analysis of multiple published simulations of crop yields predicts aggregate production losses for wheat, rice (Oryza sativa), and maize in both temperate and tropical ...

Plant Safety
Before you go hiking, learn about the poisonous plants on your favorite hiking spots. A popular maxim for avoiding poison ivy and poison oak is, "leaves of three, let it be," meaning the plant has three leaves on a single stem. Their poisonous oil, called Urushiol, gives these plants a waxy appearance. If you know an area you enjoy hiking ...
Plant adaptations: types and examples
Some examples of plants that adapt to this type of soil are chestnut and cork oak. We also have halophilic plants, which grow in soils with high salinity, which makes it difficult to capture water. In addition, there are also gypsiculous plants, which live in soils with a high gypsum content. The nitrophilous plants grow in soils with excess ...

Which adaptation in a berry plant is for reproduction?
Did you know that the flowers on a berry plant are its adaptation for reproduction? While thorns on the stem provide defense, sugar in the berries serves as a delicious treat, and chlorophyll in the leaves enables photosynthesis, it is the flowers that play a crucial role in the plant's ability to reproduce. Through the process of pollination ...
