TGFβ signaling related genes are involved in hormonal mediation during termite soldier differentiation. [PDF]

PLoS Genetics, 2018
A working knowledge of the proximate factors intrinsic to sterile caste differentiation is necessary to understand the evolution of eusocial insects. Genomic and transcriptomic analyses in social hymenopteran insects have resulted in the hypothesis that ...

Pluralization Challenges to Religion as a Social Imaginary: Anti-Caste Contestations of the Muslim Quota in India

Religions, 2023
Postcolonial democratic deepening brings new challenges to religion as a social imaginary in India. Increasing cultural differentiation and pluralization are countered by fundamentalization, but also challenge existing minority/multicultural imaginations.

Caste-specific phenotypic plasticity of Asian weaver ants: Revealing the allometric and non-allometric component of female caste system of Oecophylla smaragdina (Hymenoptera: Formicidae) by using geometric morphometrics

Sociobiology, 2021
In eusocial insects, particularly in ants, caste differentiation is extremely complicated when we rely on traditional taxonomy. In most species, the worker caste does not display any distinct morphological characters neither the caste’s central division ...

Regulatory Mechanisms Underlying the Differentiation of Neotenic Reproductives in Termites: Partial Release From Arrested Development

Frontiers in Ecology and Evolution, 2021
Eusocial insects exhibit reproductive division of labor, in which only a part of colony members differentiates into reproductives. In termite colonies, the division of labors is performed among multiple types of individuals (i.e., castes), such as ...

mRNA expression and DNA methylation in three key genes involved in caste differentiation in female honeybees (Apis mellifera). [PDF]

Dongwuxue Yanjiu, 2014
In honeybee ( Apis mellifera ) colonies, queens and workers are alternative forms of the adult female honeybee that develop from genetically identical zygotes but that depend on differential nourishment. Queens and workers display distinct morphologies,

Linking Genes and Brain Development of Honeybee Workers: A Whole-Transcriptome Approach. [PDF]

PLoS ONE, 2016
Honeybees live in complex societies whose capabilities far exceed those of the sum of their single members. This social synergism is achieved mainly by the worker bees, which form a female caste.

Soldier Caste-Specific Protein 1 Is Involved in Soldier Differentiation in Termite Reticulitermes aculabialis

Insects, 2022
Termite soldiers are a unique caste among social insects, and their differentiation can be induced by Juvenile hormone (JH) from workers through two molts (worker–presoldier–soldier).

Genome-Wide Differential DNA Methylation in Reproductive, Morphological, and Visual System Differences Between Queen Bee and Worker Bee (Apis mellifera)

Frontiers in Genetics, 2020
There are many differences in external morphology and internal physiology between the Apis mellifera queen bee and worker bee, some of which are relevant to beekeeping production.

Transcriptomics on Social Interactions in Termites: Effects of Soldier Presence

Frontiers in Ecology and Evolution, 2022
The organization of social insect colonies requires sophisticated mechanisms to regulate caste composition according to colony demands. In termites, the soldier caste is responsible for the inhibition of soldier differentiation, but the mechanism ...

Ultraspiracle and caste differentiation in Apis mellifera [PDF]

, 2023
O hormônio juvenil (HJ) e os ecdisteróides, especialmente 20-hidroxiecdisona (20E), controlam muitos aspectos no desenvolvimento de insetos. Em insetos eusociais, estes hormônios estão diretamente envolvidos na diferenciação de castas alternativas. O HJ,
