    Despite the pervasiveness of media, the amount of philanthropic dollars in support of public interest media remains minuscule and, therefore largely ineffective. The report, based on a survey of the the funding sector, calls on philanthropists to embrace a practice of transparency and information sharing via technology, to determine how existing funds are being used and how they can best be leveraged to increase philanthropic impact within the media field

    Regulation of Growth in Avena Stem Segments by Gibberellic Acid and Kinetin

    Full text link
    Kinetin at physiological concentrations causes significant reduction of GA 3 -promoted growth in excised Avena stem segments. Kinetin is therefore considered to be a gibberellin-antagonist in this system. A Lineweaver-Burke plot reveals that kinetin acts non-competitively with GA 3 . The kinetin inhibition of GA 3 -promoted growth can be seen within 6 hours. It was found that soluble protein is markedly increased by kinetin in the tissue during the first 3 hours, thus preceding the inhibition of GA 3 -promoted growth by several hours. At the cellular level, kinetin negated the blocking effect of GA 3 on cell division in the intercalary meristem portions of these segments. In fact, kinetin promotes both lateral and longitudinal cell divisions in intercalary meristem cells.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/73968/1/j.1399-3054.1971.tb03524.x.pd

    Structural Development of the Oat Plant

    Get PDF
    The anatomical structure and morphology of the oat plant (Avena sativa L.) have been reviewed previously by Hector (1936), Bonnett (1961a,b) and Coffman (1977). In addition, Bonnett published detailed accounts of oat panicle development (1937, 1961a,b). This work has been summarized by Esau in her book, Anatomy of Seed Plants, in 1977. It is not the purpose of the present authors to simply go over all this same material again in a repetitive fashion, but rather, to emphasize some of the more recent and previously overlooked work on structural development of the oat plant, with emphasis on the major cultivated species, A. sativa (see Stanton, 1955; Coffman, 1977 for descriptions of this species). The material presented here should be of use to oat breeders, agronomists, and plant physiologists
