Mohd Razi Ismail, . and Mohamed Hamad Awad, . and Marziah M., . and Mahmud T. M. Mohamed, . (2000) The involvement of cell wall associated peroxidase activity in limiting Capsicum annuum L. Pepper leaf expansion during water deficit. [Proceedings Paper]
Abstract
The effect of drying soil upon spatial distribution of leaf expansion and cell wall associated peroxidase activity in currently expanding leaves of Capsicum annuum L. was investigated. Soil water deficit reduced leaf expansion dramatically compared to plants which were well watered. Assayed cell wall associated peroxidase activity increased in the leaves of plants growing in drying soil to 10 fold those found in well-watered plants of well-watered treatment. In the leaves of droughted plants highest cell wall associated peroxidase activities were observed in the regions of the leaf where expansion was occurring most rapidly in the well-watered plants. This increase in cell wall associated peroxidase activity and its spatial variation provides preliminary evidence that cell wall associated peroxidase activity may restrict cell expansion and subsequently leaf expansion in dicotlydenous species Capsicum annuum L during periods of water deficit.
