Molecular recording of mammalian embryogenesis. [PDF]
bioRxiv, 2019 Ontogeny describes the emergence of complex multicellular organisms from single totipotent cells. This field is particularly challenging in mammals, owing to the indeterminate relationship between self-renewal and differentiation, variation in progenitor

Autophagy is activated and involved in cell death with participation of cathepsins during stress-induced microspore embryogenesis in barley [PDF]
Journal of Experimental Botany, 2018 Microspores are reprogrammed towards embryogenesis by stress. Many microspores die after this stress, limiting the efficiency of microspore embryogenesis. Autophagy is a degradation pathway that plays critical roles in stress response and cell death.

Plant Regeneration via Direct Somatic Embryogenesis in Three Strawberry (Fragaria ananassa Duch.) Cultivars [PDF]
Agrotechniques in Industrial Crops, 2021 Cultivated strawberry (Fragaria×ananassa Duch.) is one of the most important fruit plants for both fresh consumption and food processing. The aim of this study was plant regeneration via direct somatic embryogenesis in three strawberry cultivars of ...

Systematic reconstruction of cellular trajectories across mouse embryogenesis
Nature Genetics, 2022 Mammalian embryogenesis is characterized by rapid cellular proliferation and diversification. Within a few weeks, a single-cell zygote gives rise to millions of cells expressing a panoply of molecular programs.

Epigenetic clocks reveal a rejuvenation event during embryogenesis followed by aging
Science Advances, 2021 Epigenetic clocks reveal a rejuvenation event during embryogenesis followed by aging. The notion that the germ line does not age goes back to the 19th-century ideas of August Weismann. However, being metabolically active, the germ line accumulates damage

The effects of sugars and growth regulators on embryo- and callusogenesis in isolated ovules culture of beetroot, Beta vulgaris L. [PDF]
Caspian Journal of Environmental Sciences, 2021 Haploid techniques have risen interest among researchers and breeders as they significantly reduce the time of creating pure lines in breeding programs, especially for biennial vegetable crops.

Genetic and Molecular Control of Somatic Embryogenesis
Plants, 2021 Somatic embryogenesis is a method of asexual reproduction that can occur naturally in various plant species and is widely used for clonal propagation, transformation and regeneration of different crops. Somatic embryogenesis shares some developmental and

Plant Physiology, 2021 Somatic embryogenesis is a type of plant cell totipotency where embryos develop from nonreproductive (vegetative) cells without fertilization. Somatic embryogenesis can be induced in vitro by auxins, and by ectopic expression of embryo-expressed ...
