Genome-wide identification and expression analysis of late embryogenesis abundant (LEA) genes reveal their potential roles in somatic embryogenesis in hybrid sweetgum (Liquidambar styraciflua × Liquidambar formosana)

Forestry Research, 2023
Late embryogenesis abundant (LEA) proteins are widely distributed in higher plants that play significant roles in embryonic development and abiotic stress response.

Somatic mutations in human ageing: New insights from DNA sequencing and inherited mutations [PDF]

arXiv, 2023
The accumulation of somatic mutations is a driver of cancer and has long been associated with ageing. Due to limitations in quantifying mutation burden with age in non-cancerous tissues, the impact of somatic mutations in other ageing phenotypes is unclear.

Brownian-like deviation of neighboring cells in the early embryogenesis of the zebrafish [PDF]

Physical Biology, Institute of Physics: Hybrid Open Access, 2019, 16 (2), pp.024001, 2019
We investigate cell trajectories during zebrafish early embryogenesis based on 3D+time photonic microscopy imaging data. To remove the collective flow motion and focus on fluctuations, we analyze the deviations of pairs of neighboring cells. These deviations resemble Brownian motion and reveal different behaviors between pairs containing daughter cells

Long-Term Maintainable Somatic Embryogenesis System in Alfalfa (Medicago sativa) Using Leaf Explants: Embryogenic Sustainability Approach

Plants, 2019
Alfalfa (Medicago sativa) is one of the most important forage legume crops because of its mass production and high feeding value. It originated in Asia and is one of the most ancient plants cultivated throughout the world as a fodder.

Improvement of callogenesis and somatic embryogenesis by selecting optimal hormonal balance in Sarnav and Desiree potato varieties

Agriculture, 2023
Callus formation and somatic embryogenesis in potato varieties are effective ways to obtain an entire plant from a single cell. The implementation of embryogenesis is widely used in improving plant materials and creating new biotechnological varieties ...

Oil Palm Phytochrome-Interacting Factor4 (PIF4) Gene is Conserved and Highly Expressed During Somatic Embryogenesis

Hayati Journal of Biosciences, 2019
Oil palm is used in food, fuel and cosmetic industries. Tissue culture is the best way to propagate oil palm; unfortunately the somatic embryogenesis during tissue culture takes long time.

Somatic Embryogenesis: Identified Factors that Lead to Embryogenic Repression. A Case of Species of the Same Genus.

PLoS ONE, 2015
Somatic embryogenesis is a powerful biotechnological tool for the mass production of economically important cultivars. Due to the cellular totipotency of plants, somatic cells under appropriate conditions are able to develop a complete functional embryo.

Molecular mechanism of somatic embryogenesis in paeonia ostii ‘Fengdan’ based on transcriptome analysis combined histomorphological observation and metabolite determination

BMC Genomics, 2023
Background Tree peony (Paeonia sect. Moutan DC.) is a famous flower native to China with high ornamental, medicinal, and oil value. However, the low regeneration rate of callus is one of the main constraints for the establishment of a genetic ...

Abnormalities in somatic embryogenesis caused by 2,4-D: an overview

Plant Cell Tissue and Organ Culture, 2019
Somatic embryogenesis is a morphogenetic event where somatic cells have the ability to produce embryos without gamete fusion. It is used as a technique for plant mass propagation.

Automation and Scale Up of Somatic Embryogenesis for Commercial Plant Production, With Emphasis on Conifers

Frontiers in Plant Science, 2019
For large scale production of clonal plants, somatic embryogenesis (SE) has many advantages over other clonal propagation methods such as the rooting of cuttings.
