“…By contrast, pigments that do not participate in assimilation of light energy (exemplified by secondary Car) are not so strictly controlled genetically and may vary over a much wider range e.g. during senescence and/or under stress (Green and Durnford, 1996;Young, 1993).…”

“…Although the concentration of chlorophyll a may decrease with decreasing temperature, carotenoid concentrations often remain high (Young, 1993) because low temperature induces photoinhibition (Falk et al, 1990 ;Davison, 1991 ;Krause, 1993). Carotenoids may act as a screening pigment that blocks excess light, as well as scavenging reactive oxygen species, thereby decreasing the damaging effects of intense illumination at low temperatures (Krause, 1993).…”

Although mat-forming cyanobacteria dominate many freshwater ecosystems in the Arctic and Antarctic, their optimal temperature for growth (T opt ) is usually much higher than the temperature range of their native habitat. The present study compared the temperature dependence of growth, pigment composition and absorbance, photosynthesis and photosynthate partitioning for two strains of cyanobacteria with contrasting T opt values ; Phormidium subfuscum, isolated from McMurdo Ice Shelf, Antarctica, and Phormidium tenue, collected from the Kuparuk River in the tundra region of northern Alaska. Phormidium subfuscum grew between 5 and 20mC with a T opt of 15mC whereas P. tenue showed detectable growth from 10 to 40mC and a T opt of 30mC. Light utilization efficiency, photosynthetic capacity and the irradiance at the onset of light saturation increased with increasing temperature up to T opt in both strains. The cellular concentrations of chlorophyll a (Chl a) and carotenoid (CAR) and the in vivo absorbance maxima for Chl a, CAR, C-phycocyanin and allophycocyanin changed little for P. subfuscum but all these variables increased across the temperature range up to T opt for P. tenue. Neither P. subfuscum nor P. tenue showed changes in relative carbon allocation with varying temperature, suggesting that gross biochemical alterations are not a characteristic of temperature acclimation in these cyanobacteria. We conclude that the eurythermal cyanobacterium P. tenue optimizes growth over a wide range of temperatures by adjusting its light-capturing as well as carbon fixation characteristics, whereas stenothermal P. subfuscum relies on changes in carbon fixation without concomitant shifts in pigment content.

“…Typically, leaves contain b-carotene (b-Car), lutein (L), violaxanthin (V) and neoxanthin (N) (Goodwin 1965;Young 1993). Part of V is converted to antheraxanthin (A) and zeaxanthin (Z) under excess light or other environmental stress conditions (Yamamoto et al 1962).…”

Abstract.A survey of photosynthetic pigments, including 86 species from 64 families, was conducted for leaves of neotropical vascular plants to study sun-shade patterns in carotenoid biosynthesis and occurrence of a-carotene (a-Car) and lutein epoxide (Lx). Under low light, leaves invested less in structural components and more in light harvesting, as manifested by low leaf dry mass per area (LMA) and enhanced mass-based accumulation of chlorophyll (Chl) and carotenoids, especially lutein and neoxanthin. Under high irradiance, LMA was greater and b-carotene (b-Car) and violaxanthin-cycle pool increased on a leaf area or Chl basis. The majority of plants contained a-Car in leaves, but the a-to b-Car ratio was always low in the sun, suggesting preference for b-Car in strong light. Shade and sun leaves had similar b,e-carotenoid contents per unit Chl, whereas sun leaves had more b,b-carotenoids than shade leaves. Accumulation of Lx in leaves was found to be widely distributed among taxa: >5 mmol mol Chl À1 in 20% of all species examined and >10 mmol mol Chl À1 in 10% of woody species. In Virola elongata (Benth.) Warb, having substantial Lx in both leaf types, the Lx cycle was operating on a daily basis although Lx restoration in the dark was delayed compared with violaxanthin restoration.
