Genotypic Differences in Reproductive Thermotolerance are Associated With Elevated Pre-Stress Antioxidant Enzyme Protection in the Cotton Pistil
نویسندگان
چکیده
Extreme year-to-year variability in yield is a major concern for Arkansas cotton farmers. This variability has been partially explained by year-to-year variation in average maximum temperature during flowering. For example, heat stress (average maximum temperatures near 95 °C) during flowering experienced by cotton plants during a typical growing season in the U.S. is a major cause of disappointingly low yields, with a correlation existing between low yields and high temperature (Oosterhuis, 2002).

Genotypic Differences in Thermotolerance are Dependent Upon Pre-Stress Capacity for Antioxidant Protection of the Photosynthetic Apparatus in Cotton
Cotton is exceptionally sensitive to high temperature during reproductive development, with a negative correlation existing between high temperatures during flowering and yield (Oosterhuis, 2002). Furthermore, reproductive thermosensitivity in cotton is closely associated with the photosynthetic thermosensitivity of the subtending leaf (Snider et al., 2009). For example, high temperature is kno...
متن کاملPollen Germination of Diverse Cotton Cultivars
High temperatures during cotton flowering and early boll development can detrimentally affect cotton yield. Current commercial cultivars do not have pronounced tolerance to elevated temperatures, and improved methods of screening for thermo-tolerance are needed. The effect of heat stress on cotton has been measured with several different methods including membrane leakage, chlorophyll fluoresce...
متن کاملProtecting cotton photosynthesis during moderate chilling at high light intensity by increasing chloroplastic antioxidant enzyme activity.
This study examined the effect of increasing chloroplastic superoxide dismutase (SOD), ascorbate peroxidase (APX), or glutathione reductase (GR) activity via plant transformation of cotton on the initial recovery of photosynthesis following exposures to 10 degrees C and high photon flux density (PFD). Growing wild-type or non-expressing segregate plants (controls) and transformants at two PFDs ...
متن کاملEvaluation of Oxidative Stress in Blood During Hemodialysis
The number of patients with end-stage renal disease is growing rapidly in Asia. Patients with end stage renal disease failure (ESRD) undergoing long term hemodialysis (HD) are at risk for high oxidative stress. There is paucity of information with regard to oxidative stress during HD. Therefore, the aim of the present study was to evaluate catalase enzyme activity in erythrocytes and the total ...
متن کاملEffect of Drought Stress on Lipid Peroxidation and Proline Content in Cotton Root
Oxidative damage and antioxidant responses were compared in two cotton cultivars: drought-resistant (CCRI-60) and drought-sensitive (CCRI-27). Cotton seedlings were subjected to PEG-6000 solutions with two different osmotic potentials, and changes in the antioxidant enzyme activities were investigated. Increasing PEG concentration reduced root length and vigor, increased H2O2, malondialdehyde (...
