Environmental Factors Regulate Plant Secondary Metabolites.

Abiotic environmental stresses can alter plant metabolism, leading to inhibition or promotion of secondary metabolites. Although the crucial roles of these compounds in plant acclimation and defense are well known, their response to climate change is poorly understood. As the effects of climate change have been increasing, their regulatory aspects on plant secondary metabolism becomes increasingly important.

Individual and interactive effects of temperature and light intensity on canola growth, physiological characteristics and methane emissions.

Earlier studies have shown that plants produce methane (CH) under aerobic conditions, and that this emission is not microbial in nature. However, the precursors of aerobic CH remain under debate, and the combined effects of environmental factors on plant-derived CH requires further attention. The objective of this study was to determine the interactive effects of temperature and light intensity on CH and other relevant plant parameters in canola (Brassica napus L.

Environmental Factors Influence Plant Vascular System and Water Regulation.

Developmental initiation of plant vascular tissue, including xylem and phloem, from the vascular cambium depends on environmental factors, such as temperature and precipitation. Proper formation of vascular tissue is critical for the transpiration stream, along with photosynthesis as a whole. While effects of individual environmental factors on the transpiration stream are well studied, interactive effects of multiple stress factors are underrepresented.

Unravelling the effects of blue light on aerobic methane emissions from canola.

It is now well documented that plants produce methane (CH) under aerobic conditions. However, the nature of methane production in plants and all the potential precursors and environmental factors that can be involved in the process are not fully understood. Earlier studies have suggested several chemical compounds, including the amino acid methionine, as precursors of aerobic methane in plants, but none have explored other amino acids as potential precursors or blue light as a driving force of methane emission.

Light quality and quantity regulate aerobic methane emissions from plants.

Studies have been mounting in support of the finding that plants release aerobic methane (CH ), and that these emissions are increased by both short-term and long-term environmental stress. It remains unknown whether or not they are affected by variation in light quantity and quality, whether emissions change over time, and whether they are influenced by physiological parameters. Light is the primary energy source of plants, and therefore an important regulator of plant growth and development.
