(PDF) Effects of Low Substrate Oxygen on Plant Growth
Low oxygen -sensing in plants O 2 is a rate-limiting substrate for aerobic organisms, and so a balance between O 2 availability and consumption is necessary for efficient metabolism (Kosmacz and Weits, 2014).
Hypoxia stress
Oxygen (O2) is an inhibiting factor for plant growth and development in submerged and flooding environments. Plants experience different O2 concentrations, such as normoxia, hypoxia, and anoxia, which can change over space and time. Plants have evolved various morphological, physiological, and biochemical adaptations to withstand low O2 stress, many of which have been well investigated. This ...
This suggests that low oxygen conditions in these meristems acts as a favourable condition for plant development. To search for integrators of variable oxygen concentrations into developmental programmes, recent studies have been directed to oxygen -dependent substrates of the Arg/N-degron pathway (Varshavsky, 2019).
Oxygenation of Nutrient Reservoirs in Substrate
Research comparing water-based and substrate -based cultivation systems has demonstrated that substrate -grown plants can thrive even when oxygen supply through irrigation is potentially growth limiting, as long as the substrate maintains adequate air-filled porosity (1).
These tools, adapted from animal, yeast, and bacterial research, or newly designed for plants , allow precise control of oxygen -related processes. The authors identify potential challenges limiting adoption of synthetic biology approaches, such as hurdles to application in nonmodel species and the need for improved prototyping methods.
Plant Responses to Hypoxia
When plants are subjected to waterlogged conditions, they endure a stressful environment characterized by hypoxia ( oxygen deficiency) or anoxia (complete absence of oxygen ). This oxygen -limited environment forces a metabolic shift from aerobic respiration to anaerobic fermentation, drastically compromising plant growth , development, and survival.
Hypoxia as challenge and opportunity
Introduction Oxygen is essential for plant survival. It supports a wide array of metabolic processes, including respiration. Hence, limitations in oxygen availability can pose a serious threat to plant life. Hypoxia can occur due to various environmental factors, such as flooding or ice encasement, pathogen infection, and is also intrinsic to high altitude. Hypoxia triggers a complex cascade ...
