TLDR
A rapid and easy technique for the simultaneous demonstration of lipids and starch in the same histological section is described and starch is shown as white grains contrasting with the blue-grey embedding resin.
The ratio of campesterol to sitosterol that modulates growth in Arabidopsis is controlled by STEROL METHYLTRANSFERASE 2;1.
TLDR
SMT2;1 has a crucial role in balancing the ratio of campesterol to sitosterol in order to fit both growth requirements and membrane integrity, indicating specific sterol requirements to promote normal development.
Early events in microprojectile bombardment: cell viability and particle location
Summary Tungsten and gold particles, coated with plasmid DNA harboring the β-glucuronidase (GUS) and neomycin phosphotransferase II (npt-II) genes, were delivered into tobacco primary leaves and…
Agrobacterium-mediated transformation of sunflower (Helianthus annuus L.) shoot apices: transformation patterns
TLDR
Apical segments of embryonic axes of sunflower embryos submitted to co-culture experiments with a disarmed strain of Agrobacterium tumefaciens, harbouring a plasmid coding for the marker enzyme β-glucuronidase are consistent with the hypothesis that transformed shoots originate from transformation events that have occurred within the existing meristems.
Somatic embryogenesis and organogenesis induced on the immature zygotic embryo of sunflower (Helianthus annum L.) cultivated in vitro: role of the sugar
TLDR
Experiments indicate that a minimal threshold level of both, sugar supply and osmotic pressure, are required for somatic embryogenesis, but not organogenesis, to occur.
Formation of epiphyllous buds in sunflower (Helianthus annuus L.) : induction in vitro and cellular origin
Immuno-cytochemical localization of indole-3-acetic acid during induction of somatic embryogenesis in cultured sunflower embryos
TLDR
Direct evidence presented here indicates that an endogenous auxin pulse is indeed among the first signals leading to the induction of somatic embryogenesis.
Changes in leaves of susceptible and resistant Solanum dulcamara infested by the gall mite Eriophyes cladophthirus (Acarina, Eriophyoidea)
TLDR
Mites feeding on resistant plants rapidly initiate a hypersensitive response detectable after 10 min on injured epidermal cells which then leads to severe necrosis of surrounding tissues after 1 h, and no typical feeding punctures or callose deposits appear on injured cell walls.
Transient gene expression in sunflower (Helianthus annuus L.) following microprojectile bombardment
Early cellular events during organogenesis and somatic embryogenesis induced on immature zygotic embryos of sunflower (Helianthus annuus)
TLDR
This system provides a model that can be used to study early biochemical and molecular events taking place in explants at the onset of organogenesis and somatic embryogenesis, as these two processes occur in a predictable manner and ...
