Multiple forms of invertase in developing oat internodes.
Three different invertases are found in the developing internodes of oat (Avena sativa cv. Victory). Two soluble invertases (I and II) are separable on diethylaminoethylcellulose and Sephadex columns. They are further distinguished by their kinetic constants, heat stability, and differences in stability and apparent activity optima in response to pH treatments. Relative activities of the two so...
متن کاملPromotion of growth and invertase activity by gibberellic Acid in developing Avena internodes.
Gibberellic acid (GA(3)) induces invertase activity within 6 hours in Avena stem segments that are incubated in the dark at 23 degrees . The maximum amount of promotion is about 5 times that of invertase activity in untreated segments. GA(3) causes significant promotion of invertase activity at concentrations as low as 3 x 10(-5) mum GA(3). The increase in invertase activity elicited by GA(3) b...
متن کاملMultiple myeloma and oat cell carcinoma.
An association linking multiple myeloma with a higher incidence of carcinomatous tumours has been reported. The following case report describes a man diagnosed as having bronchogenic carcinoma found also to have myelomatosis. Aspects of this association are discussed.
متن کاملGrowth, in vivo extensibility, and tissue tension in developing pea internodes.
The relationship between growth, in vivo extensibility, and tissue tension in the first 3 internodes of 5, 6, and 7 day-old pea plants (Pisum sativum L. cv Alaska), grown under continuous red light was investigated. The upper 15 millimeters of each internode was marked with ink and its elongation growth measured over the next subsequent 8 hours. In vivo extensibility was measured by stretching ...
متن کاملSilicification of developing internodes in the perennial scouring rush (Equisetum hyemale var. affine).
An electron microprobe (EMP) analysis of silica (SiO,) deposition in the epidermis of developing internodes of the perennial scouring rush (Equisetum hyemale var. affine) indicates that SiO, is first detected in the stomata1 apparatus beginning with internode 3, then the epidermal papillae (internode 8), and finally in radial cell walls of the long epidermal cells (internode 10). This process i...
