    Description: Concretions of iron and manganese oxides and hydrous oxidesóobjects commonly called manganese nodulesóare widely distributed not only on the deep-sea floor but also in shallow marine environments1. Such concretions were not known to occur north of Cape Mendocino in the shallow water zones bordering the North-East Pacific Ocean until the summer of 1966 when they were recovered by one of us (J. W. M.) in dredge samples from Jervis Inlet, a fjord approximately 50 miles north-west of Vancouver, British Columbia.

    Notes: Modern terrigenous sediments cemented by low-magnesian calcite are found in distributary channels and adjacent shallow-water marine localities at the front of the Fraser River delta. These permanently submerged areas are usually covered by sea water, including sea water intruded upstream along bottoms of river channels. The cemented sediments occur as irregular to platy nodular masses at or near to sediment-water interface, where they are frequently encountered during dredging. The cement consists of small crystals arranged in fibrous rims and other aggregates around and between sand grains. Processes leading to cementation are not yet known, but may include dissolution of calcareous shells by pore waters in buried sediments, followed by precipitation of calcite at higher levels from these fluids as they are expelled upward during compaction.

    Description / Table of Contents: Zusammenfassung Die Anthocyanbildung war im langfristig gegebenen Dunkelrot bis zu etwa 60% reduziert, wenn die ersten 6 Std durch hellrote oder blaue Bestrahlung ersetzt wurden; Hellrot oder Dunkelrot in gleicher Weise im Dauerblaulicht substituiert waren praktisch wirkungslos. Daraus wird geschlossen, daß der Effekt einer Dauerbestrahlung mit Blau und Dunkelrot zum Teil jedenfalls, auf verschiedene Photorezeptoren zurückzuführen ist. Der Effekt einer Vorbehandlung mit hellrotem oder blauem Licht trat auch dann auf, wenn nur kurzfristige Bestrahlungen gegeben wurden und konnte durch unmittelbar nachfolgende kurze Dunkelrot-Belichtung wieder aufgehoben werden. Die Hemmung durch kurzfristige Vorbestrahlung konnte weitgehend verhindert werden, wenn die Keimlinge während der Dunkelperiode, vor der Übertragung in Dauerdunkelrot, bei tiefer Temperatur oder unter Stickstoff gehalten wurden. Der Vorbelichtungseffekt wird auf die enzymatische Destruktion von Phytochrom, nach der Umwandlung in die P FR -Form, zurückgeführt und es wird vermutet, daß die Anthocyansynthese im Dauerdunkelrot weitgehend phytochromabhängig ist, wahrscheinlich durch die Aufrechterhaltung eines niedrigen P FR Niveaus im Gewebe infolge der schwachen Absorption von P R im Dunkelrot. Eine Vorbelichtung mit Hellrot verringerte ebenfalls die hemmende Wirkung von Dunkelrot auf das Hypokotylwachstum, war jedoch ohne Einfluß im Blaulicht.
    Notes: Summary The substitution of red or blue light for the first six hours of prolonged irradiation with far-red light reduced anthocyanin formation by about 60%; red or far-red light similarly substituted for blue light had little effect. It is concluded that the effects of prolonged irradiation with blue and far-red depend, in part at least, on different photoreceptors. The effects of pre-treatment with red or blue light also occurred when only short exposures to light were given, and were reversed by immediate brief exposures to far-red. The depressing effect of a short pre-irradiation treatment was largely prevented if seedlings were kept at low temperature or in an atmosphere of nitrogen in the dark period before transfer to the prolonged far-red treatment. The effect of the pre-irradiation treatment is attributed to enzymatic destruction of phytochrome following conversion to the P FR form, and it is suggested that anthocyanin synthesis in far-red light largely depends on phytochrome, possibly due to the maintenance of a low level of P FR in the tissue by the absorption tail of P R in the far-red. A pre-irradiation treatment with red also decreased the inhibitory effect of far-red on hypocotyl elongation but did not change the response to blue light.

    Notes: Summary Kinetic studies of anthocyanin formation in far-red and red light given in various combinations have shown that the responses to the two wave-lengths are different and depend on the sequence of irradiation. Red light reduced the effectiveness of subsequent prolonged far-red regardless of whether red began the irradiation or was interposed after several hours of far-red. However, far-red eventually regained some activity to a degree which depended on seedling age and the duration of the initial exposure to red light. It is suggested that red light may act by destroying the labile form of phytochrome (presumed to be required for far-red action) and that the resumption of far-red activity may indicate new synthesis of such phytochrome. When given after several hours of far-red, the yield in prolonged red light was markedly increased and, in intact hypocotyls, anthocyanin synthesis then proceeded as rapidly in red as in far-red. Far-red also increased the yield in subsequent red light when given after an initial irradiation with read and, under these conditions, anthocyanin yield in hypocotyls was even greater if seedlings were transferred to red light than if the far-red was continued. Red light appeared to favour formation of anthocyanin in the hypocotyl and it is possible that the action of red is to block synthesis in the cotyledons thus leading to an increased translocation of substrate to the hypocotyl. A number of treatments increased the yield of cotyledons in red light but, unlike the hypocotyls, they never reached that obtained with far-red. Several observations indicated that the increased effectiveness of red, when given after far-red, might be due to the accumulation of substrate in far-red, which is then converted to anthocyanin by the action of the stable form of phytochrome.

    Description / Table of Contents: Zusammenfassung Die Beteiligung des reversiblen Hellrot-Dunkelrot-Pigmentsystems Phytochrom wurde bei der Kontrolle der Anthocyansynthese in Keimlingen von Brassica rapa nachgewiesen. Durch kurze Hellrotbestrahlung wird der Anthocyangehalt gegenüber dem der vorausgehenden Bestrahlung mit Blaulicht erhöht. Dieser Effekt wird durch eine nachfolgende kurze Bestrahlung mit Dunkelrot wieder mehr oder weniger aufgehoben. Die Empfindlichkeit gegen Rotlicht ist weitgehend auf 24 Std alte, in Wasser gewachsene Keimlinge beschränkt. Die Empfindlichkeit konnte in älteren Keimlingen wieder hergestellt werden, wenn diese in Phenylalanin aufgezogen und mehrere Stunden vor der Bestrahlung bei hoher Temperatur (35°C) gehalten wurden. Unter diesen Bedingungen war der Phytochrom-Effekt in 48 Std alten Keimlingen größer als in 24 Std alten Keimlingen. In den jüngsten Keimpflanzen wurde die größte Zunahme durch Hellrot erzielt, wenn wenigstens 12 Std mit Blaulicht vorbestrahlt worden war. In älteren Keimlingen wurde die maximale Hellrotwirkung schon nach etwa vierstündiger Vorbelichtung erreicht. Das Hypokotylwachstum war durch das Phytochromsystem kaum beeinflußbar. Mögliche Gründe für die Veränderungen in der Phytochrom-Empfindlichkeit werden diskutiert.
    Notes: Summary The participation of the red/far-red reversible reaction of phytochrome in the control of anthocyanin formation in turnip seedlings has been demonstrated. A brief exposure to red light following a preliminary irradiation period in blue, increased anthocyanin content compared with blue alone; this effect was reversed by a subsequent short exposure to far-red. The sensitivity to red light was largely restricted to 24 hours old seedlings when grown in water at 25°C. Sensitivity was restored in older seedlings when they were grown in phenylalanine and kept in high temperature (35°C) for several hours before light was given; under these conditions, the phytochrome effect was greater in 48 hours old than in 24 hours old seedlings. In the youngest seedlings the largest increase occurred when red followed a preliminary blue exposure of at least 12 hours; in older seedlings the maximum response to red was almost attained after only 4 hours of blue light. Hypocotyl elongation was shown to be hardly affected by the reversible reaction of phytochrome. Possible reasons for these changes in sensitivity to phytochrome are discussed.
