  callus cells
Light and Nitrate Utilization by Soybean Callus Cells
      
We studied the role of light during exogenous assimilation of nitrate (the only source of nitrogen) by the callus cells of soybean (Glycine max).
      
The experimental results obtained were used to determine the possible causes of the heterogeneity of callus cells as regards their anoxia resistance.
      
In the SA-treated infected calli, the formation of necrotic lesions was observed in the zones of contact of the fungal mycelium with callus cells that limited pathogen growth.
      
Light and electron microscopic examinations revealed a large number of intracellular prismatic-shaped Ca oxalate crystals in both leaf and callus cells.

  callus cell
The concentration of cytochrome P450 and ecdysone 20-monooxygenase activity in plants and callus cell culture of carpet bugleweed Ajuga reptans L.
      
It was demonstrated that the content of ecdysteroids in callus cell culture is higher than in the intact plant, with concurrent retention of a high ecdysone-20-monooxygenase activity.
      
All other cell lines contain a ribosome inhibitor, although only two callus cell lines show detectable amounts of immunoreactive proteins at the same Mr as dodecandrin.
      
Therefore, it appears that the ability of callus cell to differentiate into somatic embryos increases in the following order: octoploid >amp;lt; diploid >amp;lt; tetraploid.
      
The observed site of somatic embryo origin (SSEO) could originate from a superficial callus cell, possibly indicating a unicellular origin, or from epidermal and subepidermal callus cells, representing a multicellular origin.

Botrytis cinerea Persoon isolated from Fraguria ananassa was grown well in Peberdy's liquid medium(pH3-4) at 25℃ and produced toxin which inhibits the cell activity of the callus of Fraguria ananassa. The highest toxicity of culture filtrates occurred on the twentieth day after incubation. The crude toxin was obtained from condensed culture filtrates by extraction with chloroform. The toxin exhibited absorption maximum at 269nm.

草莓灰霉病菌(Botrytis cinerea Persoon)在25℃、pH3~4的Peberdy培养基中生长良好,并可产生引起草莓愈伤组织细胞死亡的毒素。产生毒素的高峰期为静置培养20天。灰霉菌发酵液中的毒素可用氯仿进行提取,经提取后的毒素液在269nm处有吸收峰。本研究建立了利用草莓愈伤组织细胞的荧光活性测定毒力的方法。

Longitudinal and transverse sections of graft unions of 1 or 2 year'Red Fuji'apple trees'T'budded on M7,M26 and Mains micromalus seedlings were obtained for a photomicroscopic observation. In summary,the abundant callus from rootstock and scion bud differentiated with different directions and varied degrees.The connective cambium in callus differentiated along that already existent in the scion and rootstock.In the abnormal tissues near the graft union and in the transitional area, vascular,fiber and cells of ray with great proportion extended to a lesser extent in length,wider in diameter and crooked. In the graft union of dwarfing rootstock M26, callus had the most cell layers,and vessel was in the least coaxial;in graft union of standard rootstockM.micromallus seedling,callus had the least cell layers,vessel was in the most coaxial;simidwarfing rootstock M7 was intermediate.
