SOMATIC EMBRYOGENESIS AND MORPHOANATOMY OF Ocotea porosa SOMATIC EMBRYOS [PDF]

, 2013
Ocotea porosa seeds have strong tegument dormancy, recalcitrant behavior, low and irregular germination and that makes its natural propagation difficult.

Organoids in pediatric cancer research

FEBS Letters, EarlyView.
Organoid technology has revolutionized cancer research, yet its application in pediatric oncology remains limited. Recent advances have enabled the development of pediatric tumor organoids, offering new insights into disease biology, treatment response, and interactions with the tumor microenvironment.

Hyperosmotic stress induces PARP1‐mediated HPF1‐dependent mono(ADP‐ribosyl)ation

FEBS Letters, EarlyView.
Sorbitol‐induced hyperosmotic stress rapidly induces reversible mono(ADP‐ribosyl)ation (MARylation) on PARP1 without the signs of genotoxic signaling. We show that PARP1 autoMARylation is HPF1 dependent and forms hydroxylamine‐resistant O‐glycosidic linkages.

Residual tail twisting in ascidian larvae is stabilized by asymmetric myofibrils that resist bilateral symmetry restoration

FEBS Letters, EarlyView.
Ascidian Ciona larvae initially show strong clockwise tail twisting, which is largely corrected during development. However, a small residual twist remains. This study shows that organized helical myofibrils in tail muscles mechanically stabilize this residual asymmetry, preventing complete restoration of bilateral symmetry and revealing how embryos ...

Cellular origin and development of secondary somatic embryos in Oncidium leaf cultures

, 2012
We report here for the first time that fully differentiated stomatal guard cells have the ability to form directly secondary somatic embryos. Histological and scanning electron microscopy studies reveal that the stomata are formed on primary embryos of ...

Somatic embryos from Phalaenopsis classic Spotted Pink (Orchidaceae) protocorms

Ciência Rural
: The aim of the present study was to induce the formation of somatic embryos in protocorms from Phalaenopsis Classic Spotted Pink hybrids at two physiological maturation stages, namely: 80 and 120 days after seed inoculation (DASI).
