Transcriptome Analysis Reveals Key Genes Involved in Weevil Resistance in the Hexaploid Sweetpotato

open access: yesPlants, 2021
Because weevils are the most damaging pests of sweetpotato, the development of cultivars resistant to weevil species is considered the most important aspect in sweetpotato breeding.

Krüppel-homologue 1 regulates the development of Tuta absoluta and its cascade regulation pattern in the juvenile hormone signalling pathway

open access: yesOpen Biology, 2023
Tomato leaf miner, Tuta absoluta (Meyrick), is one of the most destructive quarantine pests globally. It has been confirmed that Krüppel-homologue 1 (kr-h1) plays a key role in the regulation of juvenile hormone (JH).

Inducible Expression of Several Drosophila melanogaster Genes Encoding Juvenile Hormone Binding Proteins by a Plant Diterpene Secondary Metabolite, Methyl Lucidone

open access: yesInsects, 2022
Juvenile hormones prevent molting and metamorphosis in the juvenile stages of insects. There are multiple genes encoding a conserved juvenile hormone binding protein (JHBP) domain in a single insect species.

Reproductive Toxicity and Recovery Associated With 4-Non-ylphenol Exposure in Juvenile African Catfish (Clarias garepinus)

open access: yesFrontiers in Physiology, 2022
Although, the effects of 4-non-ylphenol (4-NP) on fish’s reproductive hormones were assessed in several studies using adult models, however, the effect of this endocrine disruptor on immature fish’s reproductive hormones was not addressed commonly.

Aspergillus nidulans synthesize insect juvenile hormones upon expression of a heterologous regulatory protein and in response to grazing by Drosophila melanogaster larvae. [PDF]

open access: yesPLoS ONE, 2013
Secondary metabolites are known to serve a wide range of specialized functions including communication, developmental control and defense. Genome sequencing of several fungal model species revealed that the majority of predicted secondary metabolite ...

Reinvigoration/Rejuvenation Induced through Micrografting of Tree Species: Signaling through Graft Union

open access: yesPlants, 2021
Trees have a distinctive and generally long juvenile period during which vegetative growth rate is rapid and floral organs do not differentiate. Among trees, the juvenile period can range from 1 year to 15–20 years, although with some forest tree species,

Juvenile phase: an important phase of the life cycle in plants

open access: yesOrnamental Plant Research, 2023
The juvenile phase of plants refers to the period from seed germination to the period in which they gain flowering ability. The phase is vital for the breeding of new plant varieties, the study of plant stress and immune responses, and the utilization of

Structural basis for juvenile hormone biosynthesis by the juvenile hormone acid methyltransferase [PDF]

open access: yesJournal of Biological Chemistry, 2021
Juvenile hormone (JH) acid methyltransferase (JHAMT) is a rate-limiting enzyme that converts JH acids or inactive precursors of JHs to active JHs at the final step of JH biosynthesis in insects and thus presents an excellent target for the development of insect growth regulators or insecticides.

Hormones as adaptive control systems in juvenile fish

open access: yesBiology Open, 2020
Growth is an important theme in biology. Physiologists often relate growth rates to hormonal control of essential processes. Ecologists often study growth as a function of gradients or combinations of environmental factors.
