Apomixis is a form of asexual reproduction in plants where embryos and clone seeds are formed directly without meiosis and fertilization. The progenies generated through apomixis are genetically identical to the maternal plants, and the genotypes does not change across generations, and the phenotypes do not undergo segregation. Successful introduction of apomixis into major crops and permanent, can achieve the permanent fixation of crop heterosis, will resulting in significant economic benefits. Parthenogenesis constitutes a pivotal component in artificial apomixis, facilitating the transition from sexual reproduction to unisexual reproduction. In this review, we summarize the recent studies on plant parthenogenesis genes, and provide an overview of the application in haploid breeding and apomixis system. This contributes to a deeper and comprehensive understanding of parthenogenesis, offering important references for its application in apomixis.

The egg parasitoids, Trichogramma spp. are important biological control agents targeting various lepidopteran pests in agriculture. However, laboratory rearing often reduces genetic diversity, and potentially decreased fitness of Trichogramma wasps.

A typical seed of rice ( L.) gives rise to a single seedling. In contrast, seeds from multiple embryos may develop into two or more seedlings, one of which is generated via sexual reproduction, while the others are likely to originate through apomictic pathways.

Apomixis is a form of asexual reproduction that produces offspring with the same genetic material as the female parent. Introducing apomixis into major food crops would revolutionize agricultural breeding by allowing the self-propagation of superior hybrids. We found that the MADS-box transcription factor D-class member AGAMOUS-like 11 (AGL11) plays a key role in the apomictic species Zanthoxylum bungeanum during somatic embryogenesis.

Candidatus Cardinium hertigii (Cardinium) are maternally transmitted obligate intracellular bacteria found in a wide range of invertebrate hosts, including arthropods and nematodes. Infection with Cardinium has substantial consequences for host biology, with many strains manipulating host reproduction to favor symbiont transmission by (i) feminizing male hosts, (ii) altering host sex allocation, (iii) inducing parthenogenesis, or (iv) causing cytoplasmic incompatibility. Other Cardinium strains can confer benefits to their host or alter host behavior.

Background: Sex differentiation is a crucial process that determines the sex ratio of a population, impacting reproductive success and ecological dynamics. In parasitoid wasps and other insects, the sex ratios significantly influence ecological adaptability and biological control potential. Particularly in parasitoid wasps, the regulation of sex ratio is closely linked to the shift between gamogenesis and parthenogenesis.
