The shade‐avoidance syndrome: multiple signals and ecological consequences

Plant Cell & Environment, Journal Year: 2017, Volume and Issue: 40(11), P. 2530 - 2543

Plants use photoreceptor proteins to detect the proximity of other plants and activate adaptive responses. Of these photoreceptors, phytochrome B (phyB), which is sensitive changes in red (R) far-red (FR) ratio sunlight, one that has been studied greatest detail. The molecular connections between signal (low R:FR) a model physiological response (increased elongation growth) have now mapped considerable detail Arabidopsis seedlings. We briefly review our current understanding discuss recent progress establishing roles photoreceptors regulating growth-related pathways competition cues. also consider processes than are controlled by contribute plant fitness under variable light conditions, including photoresponses optimize utilization soil resources. In examining advances field, we highlight emerging phyB as major modulator hormones related immunity, particular salicylic acid jasmonic (JA). Recent attempts manipulate signals defence suggest it might be possible improve crop health at high planting densities targeting links JA signalling.

Light-Quality Manipulation to Control Plant Growth and Photomorphogenesis in Greenhouse Horticulture: The State of the Art and the Opportunities of Modern LED Systems

Journal of Plant Growth Regulation, Journal Year: 2021, Volume and Issue: 41(2), P. 742 - 780

Abstract Light quantity (intensity and photoperiod) quality (spectral composition) affect plant growth physiology interact with other environmental parameters cultivation factors in determining the behaviour. More than providing energy for photosynthesis, light also dictates specific signals which regulate development, shaping metabolism, complex phenomenon of photomorphogenesis, driven by colours. These are perceived even at very low intensity five classes photoreceptors, have been characterized their biochemical features physiological roles. Knowledge about photomorphogenesis increased dramatically during last years, thanks diffusion light-emitting diodes (LEDs), offer several advantages compared to conventional sources, such as possibility tailor spectrum intensity, depending on requirements different crops development stages. This knowledge could be profitably applied greenhouse horticulture improve production schedules crop yield quality. article presents a brief overview effects artificial lighting vegetable ornamental crops, state art research LEDs horticulture. Particularly, we analysed these approaching, when possible, each single-light waveband, most review works available literature considers influence combined spectra.

Influence of Environmental Factors Light, CO2, Temperature, and Relative Humidity on Stomatal Opening and Development: A Review

Agronomy, Journal Year: 2020, Volume and Issue: 10(12), P. 1975 - 1975

Published: Dec. 15, 2020

Stomata, the microscopic pores surrounded by a pair of guard cells on surfaces leaves and stems, play an essential role in regulating gas exchange between plant surrounding atmosphere. Stomatal development opening are significantly influenced environmental conditions, both short long term. The rapid rate current climate change has been affecting stomatal responses, as new balance photosynthesis water-use efficiency to be found. Understanding mechanisms involved regulation adjustment provides us with insights into ability stomata process information evolve over time. In this review, we summarize recent advances research underlying interaction factors opening. Specific emphasis is placed including light, CO2 concentration, ambient temperature, relative humidity, these significant understanding impact global development.
