A Pentaradial and Bilateral Combined Photoreception System in the Sea Cucumber is Mediated by a Blue Light‐Sensitive R‐Opsin

Advanced Science, EarlyView.
The sea cucumber Holothuria leucospilota detects blue and adjacent wavelengths of light via an r‐opsin with a maximum absorption at 459 nm. In the oral tentacles, papillae, and tube feet, distinct light‐sensing structures with specialized morphologies are formed, constituting a unique pentaradial and bilateral combined photoreception system.

Effects of Photoperiod and Temperature on Energy Budgets and Endocrine Hormones Concentrations in Tupaia belangeri [PDF]

Journal of Stress Physiology & Biochemistry, 2014
Environmental cues play important roles in the regulation of an animal’s physiology and behavior. In the present study, we performed a factorial experiment (temperature/photoperiod) in which Tupaia belangeri was acclimated to different photoperiods (long

Auto‐Downregulation of the Florigen FT Production Prevents Precocious Flowering in Plants

Advanced Science, EarlyView.
This study shows that the leaf vein‐expressed FD complexes with the florigen FT to bind DNA motifs in FT promoter, which antagonizes CONSTANS‐mediated FT activation to feedback down‐regulate FT expression. This prevents an excessive induction of FT expression by inductive photoperiods, thereby precluding precocious transition to flowering in ...

Plants Distinguish Different Photoperiods to Independently Regulate Post-Flowering Vegetative Growth and Reproductive Growth

Plants
The post-flowering stage is critical for plant yield and seed quality. This can be influenced by the photoperiod; however, the underlying mechanisms are not clear.

RNAi in the Rhizarian Phytopathogen Plasmodiophora brassicae: The Causal Agent of Clubroot Disease in Cruciferous Crops

Advanced Science, EarlyView.
This study uncovers an unusual RNAi pathway in the rhizarian pathogen Plasmodiophora brassicae. In the absence of Dicer, a Drosha‐like RNase III protein supports the biogenesis of predominant 21‐nt small RNAs, and two Argonaute proteins mediate small RNA‐guided silencing.

Photoperiod and metabolic health: evidence, mechanism, and implications [PDF]

Circadian rhythms are evolutionarily programmed biological rhythms that are primarily entrained by the light cycle. Disruption of circadian rhythms is an important risk factor for several metabolic disorders.

Molecular Editing Reveals a Bilobalide Chemotype that Attenuates Prolyl Endopeptidase (PREP)‐Linked Neuroinflammation

Advanced Science, EarlyView.
Molecular editing of bilobalide uncovers BB56, a PREP‐engaging chemotype with enhanced anti‐inflammatory activity in microglia. Integrated CETSA‐MS, SAR, and pathway analyses link BB56 to attenuation of p38 MAPK/NF‐κB and NLRP3‐associated inflammatory signaling, highlighting bilobalide editing as a strategy for developing neuroinflammation‐modulating ...

Migratory restlessness in an equatorial nonmigratory bird [PDF]

, 2006
The urge of captive birds to migrate manifests itself in seasonally occurring restlessness, termed "Zugunruhe." Key insights into migration and an endogenous basis of behavior are based on Zugunruhe of migrants but have scarcely been tested in ...
