Photoperiod-dependent changes in the phase of core clock transcripts and global transcriptional outputs at dawn and dusk in Arabidopsis.

Plant, Cell and Environment, 2016
Plants use the circadian clock to sense photoperiod length. Seasonal responses like flowering are triggered at a critical photoperiod when a light-sensitive clock output coincides with light or darkness.

An Insect Salivary Sheath Protein Triggers Plant Resistance to Insects and Pathogens as a Conserved HAMP

Advanced Science, EarlyView.
The salivary sheath protein myosin from SBPH is critical for the formation of the salivary sheath and feeding. However, myosin functions as a HAMP and triggered plant BAK1‐mediated PTI responses, which include the activation of calcium signaling pathways, MAPK phosphorylation, ROS bursts, and cell death, thereby triggering JA pathway.

The molecular basis of photoperiodism

Biological Rhythm Research, 2006
The rotation of our planet results in regular changes in environmental cues such as daylength and temperature, and organisms have evolved a molecular oscillator that allows them to anticipate these changes and adapt their development accordingly. In many plants, the transition from vegetative to reproductive growth is controlled by photoperiod, which ...

Autumn photosynthetic decline and growth cessation in seedlings of white spruce are decoupled under warming and photoperiod manipulations.

Plant, Cell and Environment, 2017
Climate warming is expected to increase the seasonal duration of photosynthetic carbon fixation and tree growth in high-latitude forests. However, photoperiod, a crucial cue for seasonality, will remain constant, which may constrain tree responses to ...

Discovery, Herbicidal Activity and Biosynthesis of a Novel Natural Tetramic Acid from Alternaria Species

Advanced Science, EarlyView.
The biosynthetic mechanism of novel natural tetramic acid S‐TeA in Alternaria alternata is elucidated. Threonine acts as a precursor for 2‐amino‐3‐methylhexanoic acid (AMHA) synthesis via eight key enzymes from the branched‐chain amino acid biosynthetic pathway in the mitochondrion, wherein three unique enzymes (IPMS, IPMDH, and ISMD) play critical ...

Photoperiod Extension Enhances Sexual Megaspore Formation and Triggers Metabolic Reprogramming in Facultative Apomictic Ranunculus auricomus

Frontiers in Plant Science, 2016
Meiosis, the key step of sexual reproduction, persists in facultative apomictic plants functional to some extent. However, it still remains unclear how and why proportions of reproductive pathways vary under different environmental stress conditions.

Nanoparticle Delivery of Antisense miR162 Inhibits Invasive Habitat Adaption of Alternanthera Philoxeroides

Advanced Science, EarlyView.
This study demonstrates that the miRNA pathway plays a key role in the invasive growth of Alternanthera philoxeroides in aquatic habitats. Specifically, miR162 is critical for its invasive success, facilitating stem elongation and enhancing survival during submergence.

Effects of simulated winter short photoperiods on the microbiome and intestinal metabolism in Huanghe carp (Cyprinus carpio haematopterus)

Frontiers in Endocrinology
ObjectiveAs one of the most important environmental signals, photoperiod plays a crucial role in regulating the growth, metabolism, and survival of organisms. The photoperiod shifts with the transition of the seasons.

Gut microbiota is associated with the effect of photoperiod on seasonal breeding in male Brandt’s voles (Lasiopodomys brandtii)

Microbiome, 2022
Background Seasonal breeding in mammals has been widely recognized to be regulated by photoperiod, but the association of gut microbiota with photoperiodic regulation of seasonal breeding has never been investigated.
