    Role of Jasmonates in Plant Adaptation to Stress

    Jasmonic acid and methyl jasmonate are naturally growth regulators widely distributed in plants. They are involved in the regulation of a multitude of processes. The functional physiology underlying these phen...

    Role of Salicylic Acid in Alleviating Heavy Metal Stress

    Both plant breeders and crop producers have an interest in finding crops capable of tolerating environmental changes with damage as little as possible. In order to develop such crops, the knowledge of plant de...

    Carboxylating enzymes and carbonic anhydrase functions were suppressed by zinc deficiency in maize and chickpea plants

    Maize and chickpea plants were grown in a controlled environment with 0.5 M Zn or without Zn and various photosynthetic reactions were studied. The chlorophyll level, the rate of photosynthesis and photosystem...

    Fluridone- and Light- Affected Chloroplast Ultrastructure and ABA Accumulation in Drought-Stressed Barley

    Fluridone and nonflurazon are selective inhibitors of carotenoid synthesis in cells. They interfere with desaturation steps of carotenoid biogenesis and thus blocks the accumulation of carotenoids (1,2,3). Car...

    Involvement of abscisic acid in photosynthetic process in Hordeum vulgare L. during salinity stress

    In Hordeum vulgare L. plants, NaCl stress imposed through the root medium for a period of 8 days decreased the rate of CO2 assimilation, the chlorophyll and protein leaf content, and the activity of ribulose-1,5-...

    Effect of abscisic acid on the photosynthetic oxygen evolution in barley chloroplasts

    In vivo effect of abscisic acid (ABA) on photosynthetic oxygen evolution was investigated in barley chloroplasts. The most important kinetic parameters of O2-producing reactions were changed. The results show inh...
