The Premammillary Nucleus of the Hypothalamus Is Not Necessary for Photoperiodic Timekeeping in Female Turkeys (\u3cem\u3eMeleagris gallopavo\u3c/em\u3e) [PDF]

open access: yes, 2018
In birds, seasonal reproduction is regulated by day length, with long days in the spring activating the hypothalamic-pituitary-gonadal axis and reproductive behaviors.

Murine Models and Human Cell Line Models to Study Altered Dynamics of Ovarian Follicles in Polycystic Ovary Syndrome

open access: yesAdvanced Biology, EarlyView.
The manuscript examines preclinical murine and human models to study polycystic ovary syndrome (PCOS), delving into the cellular and molecular mechanisms underlying altered ovarian follicular dynamics. It explores the cellular interactions involved in normal and PCOS ovaries and outlines the current and novel strategies in the search for preclinical ...

Artesunate Inhibits Neointimal Hyperplasia by Promoting IRF4 Associated Macrophage Polarization

open access: yesAdvanced Science, EarlyView.
This study shows that macrophage interferon regulatory factor 4 (IRF4) improved arterial injury‐induced neointimal hyperplasia by promoting of M2 polarization via up‐regulating krüppel‐like factor 4 (KLF4) in rodent and nonhuman primate models. Notably, artesunate is identified as a potent inducer of IRF4 in macrophages, and proposed as a promising ...

Watching the hands of the Arabidopsis biological clock [PDF]

open access: yes, 2001
Oligonucleotide and cDNA microarrays have been used to analyse the mRNA levels of 8,000 genes in Arabidopsis thaliana throughout the day/night cycle. Genes involved in signal transduction and in various metabolic pathways were found to be coordinately ...

Hierarchical Regulatory Networks Reveal Conserved Drivers of Plant Drought Response at the Cell‐Type Level

open access: yesAdvanced Science, EarlyView.
This study presents a comprehensive multi‐omics framework to uncover cell‐type‐specific regulatory networks in plant drought responses. By integrating transcriptomic, proteomic, and epigenetic data from nearly 30 000 samples, key regulators such as CIPK23 and NLP7 are identified, revealing insights into conserved drought tolerance mechanisms and ...

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

open access: yesAdvanced 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

open access: yesBiological 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 ...

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

open access: yesAdvanced 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 ...

A Parade on Molecular Control of Flowering [PDF]

open access: yes, 2016
Flower is a reproductive part of plant which contains complex array of functionally specialized structures.Photoperiodism, or the ability of an organism to detect day length, makes it possible for an event to occur at a particular time of year, thus ...

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

open access: yesAdvanced 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.
