Structure and functional genes associated with carbon, nitrogen, phosphorus, and sulfur cycling processes in periphyton: A comparison between natural and artificial rivers

River, EarlyView.
Network analysis of functional genes among prokaryotes, and eukaryotes in natural and artificial rivers. Abstract Periphyton in aquatic ecosystems plays vital roles in the elemental cycle process and is vulnerable to anthropogenic interference. However, few studies have explored the elemental cycles of carbon (C), nitrogen (N), phosphorus (P), and ...

Transcriptome Analysis Reveals Novel Insights into the Hyperaccumulator Phytolacca acinosa Roxb. Responses to Cadmium Stress

Plants
Cadmium (Cd) is a highly toxic heavy metal that causes serious damage to plant and human health. Phytolacca acinosa Roxb. has a large amount of aboveground biomass and a rapid growth rate, and it has been identified as a novel type of Cd hyperaccumulator

Complex multitrophic species interactions and fitness costs: Intricate consequences of jasmonate and salicylate induced plant defences

Journal of Animal Ecology, EarlyView.
This study reveals how long‐term activation of jasmonic and salicylic acid signalling reshapes arthropod communities and plant fitness across seasons. By showing that induced defences generate contrasting outcomes and cascading trade‐offs across trophic levels, it challenges the assumption that induced resistance is uniformly beneficial in natural ...

Synthetic Melatonin and/or Phytomelatonin Contents in Different Commercial Phytotherapeutic Supplements

Nutraceuticals
In these times and with the pace of life that we have developed, many people need help falling asleep due to poor sleep hygiene, among other reasons. Thus, in mild cases, it is recommended to use natural therapies, such as phytotherapy, avoiding in the ...

A rapid approach to investigate spatiotemporal distribution of phytohormones in rice

Plant Methods, 2016
Background Phytohormones play crucial roles in almost all stages of plant growth and development. Accurate and simultaneous determination of multiple phytohormones enabled us to better understand the physiological functions and the regulatory networks of

Russian wheat aphid: a model for genomic plasticity and a challenge to breeders

Insect Science, EarlyView.
Invasive foundress finds suitable habitat and reproduces through pathogenesis. Wingless females produce life offspring quickly, which leads to high population densities. High population densities result in competition, which may induce epigenetic changes and wing development for dispersal.

Evolutionary and expression analyses of Shaker K+ channels in Cucurbitaceae reveal potential roles of cucumber CsK1.1 and CsK2.1 in K+ transport

Plant Stress
Shaker potassium (K⁺) channels play essential roles in plant K⁺ uptake, transport, and stress responses. Although some studies have reported Shaker K⁺ channels in cucurbit species, a comprehensive genome-wide analysis across Cucurbitaceae is still ...

Effect of the microbiome on pathogen susceptibility across four Drosophilidae species

Insect Science, EarlyView.
Four Drosophilidae species were used to investigate how variation in the host microbiome influences susceptibility to infection. Microbial composition and abundance differed among species and treatments. The effects of microbiome manipulation on host survival were both species‐ and pathogen‐specific.

Trans-Kingdom sRNA Silencing in Sclerotinia sclerotiorum for Crop Fungal Disease Management

Pathogens
Sclerotinia sclerotiorum is a globally widespread and vast destructive plant pathogenic fungus that causes significant yield losses in crops. Due to the lack of effective resistant germplasm resources, the control of diseases caused by S.

Inducible tomato defences persist in detached leaves, despite differential plant variety and gene‐dependent expression

Ecological Entomology, EarlyView.
Short‐ and long‐term expression of PPO‐D, PI‐IIc and PR‐1a were assessed in intact plants and detached tomato leaves of two varieties infested with Tetranhycus urticae. Tomato defences were induced in both intact and detached leaves, but the induction levels varied with plant variety and gene assessed.
