Thermal imprinting modifies adult stress and innate immune responsiveness in the teleost sea bream [PDF]

open access: yes, 2017
The impact of thermal imprinting on the plasticity of the hypothalamic-pituitary-interrenal (HPI) axis and stress response in an adult ectotherm, the gilthead sea bream (Sparus aurata, L.), during its development was assessed.

Identification and Functions of JHE 6 Specifically Expressed in Bombyx mori Silk Gland

open access: yesInsects, 2023
Juvenile hormone esterase (JHE) is the specific enzyme that degrades juvenile hormone (JH) and regulates the JH titer in insects. JH also regulates the development of the silk gland and the synthesis and secretion of silk proteins in Bombyx mori.

Where did the pupa come from? The timing of juvenile hormone signalling supports homology between stages of hemimetabolous and holometabolous insects

open access: yesPhilosophical Transactions of the Royal Society of London. Biological Sciences, 2019
Insect metamorphosis boasts spectacular cases of postembryonic development when juveniles undergo massive morphogenesis before attaining the adult form and function; in moths or flies the larvae do not even remotely resemble their adult parents.

pax1-1 partially suppresses gain-of-function mutations in Arabidopsis AXR3/IAA17 [PDF]

open access: yes, 2007
Background: The plant hormone auxin exerts many of its effects on growth and development by controlling transcription of downstream genes. The Arabidopsis gene AXR3/IAA17 encodes a member of the Aux/IAA family of auxin responsive transcriptional ...
