chlorophyll content, disruption of photochemical capacity in photosystem II (PSII), and subsequent inhibition of the linear electron transport rate of photosynthesis in response to Al 3+ have been found in some plant species ( Chen et al., 2005 ; Peixoto et

increased linearly at low PPFD, where it was limited by electron transport rate, and gradually reached a plateau where A would be limited by Rubisco capacity ( Ogren, 1993 ). Detectable decrease in assimilation at high PPFD, an indication of photoinhibition

Pelargonium × hortorum ( Lee et al., 1996 ) and chile peppers ( Anchondo et al., 2001 ). Fe deficiency is accompanied by a decrease in all membrane components, including the electron carriers in the photosynthetic electron transport chain ( Spiller and Terry

( Groot et al., 1997 ). Total pheophytins content was less in ‘Butterfly’ than ‘Beach’ ( Table 3 ), indicating fewer electron carriers in the photosynthetic electron transport chain in the bleaching-susceptible cultivar Butterfly. A heat-induced block of

in mitochondrial electron transport under Fe deficiency. Although the function of the alternative oxidase (AOX) is not well understood, it has been shown to increase under nutrient stress, and when the rate of the tricarboxylic acid (TCA) cycle

limitations of RuBP synthesis (or electron transport rate) on photosynthesis in salvia compared with petunia. In support of this, Φ PSII (a measure of electron transport rate; Maxwell and Johnson, 2000 ) at ambient CO 2 concentration ( Fig. 5A ) was lower
