Pea Plants Show Risk Sensitivity
Sensitivity to variability in resources has been documented in humans, primates, birds, and social insects, but the fit between empirical results and the predictions of risk sensitivity theory (RST), which aims to explain this sensitivity in adaptive terms, is weak [1]. RST predicts that agents should switch between risk proneness and risk aversion depending on state and circumstances, especial...
متن کاملDifferential temperature sensitivity of pea superoxide dismutases.
The activity of pea (Pisum sativum L.) Cu/Zn and Mn superoxide dismutase isoforms was evaluated across a range of temperatures from 10 to 45 degrees C. Maximal activity of the Cu/Zn and Mn superoxide dismutase isoforms was observed at 10 degrees C. Both cytoplasmic and chloroplast Cu/Zn superoxide dismutases exhibit a reduction in staining intensity with increasing temperatures. Mn superoxide d...
متن کاملAppearance of Three Chloroplast Isoenzymes in Dark-grown Pea Plants and Pea Seeds.
Activity peaks characteristic of the chloroplastic Calvin cycle enzymes triose-phosphate isomerase, ribose 5-phosphate isomerase, and fructose 1,6-diphosphate aldolase are found in isoelectric focusing patterns of dark-grown pea (Pisum sativum) seedlings and seeds. Apparently, in this higher plant these three chloroplastic isoenzymes can be formed in the absence of light and of chloroplast form...
متن کاملEffect of Artificial dsRNA on Infection of Pea Plants by Pea seed-borne mosaic virus
Šafářová D., Brázda P., Navrátil M. (2014): Effect of artificial dsRNA on infection of pea plants by Pea seedborne mosaic virus. Czech J. Genet. Plant Breed., 50: 105–108. The effect of direct application of artificial dsRNA molecules derived from the viral coat protein gene and the possibility of RNA interference induction leading to protection against Pea seed borne mosaic virus (PSbMV) have ...
متن کاملSalicylic Acid Protects Photosynthesis against Cadmium Toxicity in Pea Plants
In the present study we have investigated the possible mediatory role of salicylic acid (SA) in protecting photosynthesis against cadmium (Cd) toxicity. The exposure of pea plants to increasing Cd concentrations (0.5, 1.0, 2.0 and 5.0 µM) during early stages of their establishment caused a gradual decrease in shoot and root fresh weight accumulation, the rate of CO 2 fixation and the activity o...
