Arabinogalactan-proteins (AGPs) are a family of extracellular plant proteoglycans implicated in many aspects of plant growth and development including in vitro somatic embryogenesis (SE). We found that specific AGPs were produced by cotton (Gossypium hirsutum) calli undergoing SE and that when these AGPs were isolated and incorporated into tissue culture media, cotton SE was promoted. When the ...

Leaves from in vitro proliferating shoots of cvs. Chandler and Hartley of Persian walnut were cultured on MS and NN media supplemented with BA and NAA. Three light conditions including darkness, low light intensity and modified light intensity were used. Most of the calli were friable and non-embryonic in all three conditions. Rate of callogenesis depended on cultivar, culture medium, light con...

This study was carried out to determine the tolerance of grass pea genotypes salinity stress at callus and seedling stages under in vitro conditions. The calli seedlings six selected tolerant based on primary screening field were separately exposed treatments (0, 125 mM) vitro. Salinity imposed with NaCl during culture, it significantly affected all traits. Genotype Iran had lowest dry weight t...
