Climate Negotiations Under Scrutiny: Are UNFCCC COPs Up To the Challenge?

Global Policy, EarlyView.
ABSTRACT The 1992 United Nations Framework Convention on Climate Change (UNFCCC) plays a crucial role in global efforts to tackle the climate crisis. At annual Conferences of the Parties (COPs) and intersessional meetings, the international community gathers to advance climate policy and action.

Prediction of photoperiodic regulators from quantitative gene circuit models [PDF]

, 2004
Photoperiod sensors allow physiological adaptation to the changing seasons. The external coincidence hypothesis postulates that a light-responsive regulator is modulated by a circadian rhythm.

LsMAPK6 Phosphorylates the LsCO Protein to Enhance Its Stability and Transcriptional Activity, Promoting Floral Transition Upon High Temperatures in Lettuce

Plant Biotechnology Journal, EarlyView.
ABSTRACT High temperatures significantly accelerate the timing of floral transition, namely, bolting and flowering, in lettuce, which results in severe loss of marketable yield. Thus, understanding the genetic regulation of floral transition is of great interest to plant biologists and lettuce breeders.

The ZmCOP1s–ZmCOL3 Module Enhances Late Flowering, Grain Yield and Grain Quality in Maize

Plant Biotechnology Journal, EarlyView.
ABSTRACT Flowering time is a key determinant of yield and regional adaptation in crops and is largely controlled by light signalling. In this study, we identified two maize orthologs of Arabidopsis CONSTITUTIVE PHOTOMORPHOGENIC 1 (COP1), designated ZmCOP1a and ZmCOP1b, which activate light signalling and reduce plant height. Loss‐of‐function mutants of

Hormonal networks involved in apical hook development in darkness and their response to light [PDF]

, 2014
In darkness, the dicot seedlings produce an apical hook as result of differential cell division and extension at opposite sides of the hypocotyl. This hook protects the apical meristem from mechanical damage during seedling emergence from the soil.

COP1 controls light-dependent chromatin remodeling

Proceedings of the National Academy of Sciences
Light is a crucial environmental factor that impacts various aspects of plant development. Phytochromes, as light sensors, regulate myriads of downstream genes to mediate developmental reprogramming in response to changes in environmental conditions. CONSTITUTIVELY PHOTOMORPHOGENIC 1 (COP1) is an E3 ligase for a number of substrates in light signaling,

Light Regulation of LoCOP1 and Its Role in Floral Scent Biosynthesis in Lilium ‘Siberia’

Plants, 2023
Light is an important environmental signal that governs plant growth, development, and metabolism. Constitutive photomorphogenic 1 (COP1) is a light signaling component that plays a vital role in plant light responses.

Enhancing Tolerance to Combined Heat and Drought Stress in Cool‐Season Grain Legumes: Mechanisms, Genetic Insights, and Future Directions

Plant, Cell &Environment, EarlyView.
ABSTRACT The increasing frequency of concurrent heat and drought stress poses a significant challenge to agricultural productivity, particularly for cool‐season grain legumes, including broad bean (Vicia Faba L.), lupin (Lupinus spp.), lentil (Lens culinaris Medik), chickpea (Cicer arietinum L.), grasspea (Lathyrus sativus L.), pea (Pisum sativum L ...

Shade delays flowering in Medicago sativa [PDF]

, 2019
Shade intolerant plants respond to the decrease in the red (R) to far-red light (FR) ratio (R:FR) occurring under shade by elongating stems and petioles and re-positioning leaves, in a race to out-compete neighbors for the sunlight resource.

Beyond Light: Insights Into the Role of Constitutively Photomorphogenic1 in Plant Hormonal Signaling

Frontiers in Plant Science, 2019
Light is an important environmental factor with profound effects in plant growth and development. Constitutively photomorphogenic1 (COP1) is a vital component of the light signaling pathway as a negative regulator of photomorphogenesis. Although the role
