“…However, protein content in leaves and roots of Yekta was higher than that of Darab 14. Changes in proteins can results from a variety of environmental stresses such as water stress (Yordanova et al 2004). According to SDS-PAGE of protein in leaves the appearance of new and colorful protein bands under some of the stress levels suggests that these proteins may be the cause of resistance to drought in sesame.…”

The effects of drought on growth, protein content, lipid peroxidation, superoxide dismutase (SOD), peroxidase (POX), catalase (CAT) and polyphenol oxidase (PPO) were studied in leaves and roots of Sesamum indicum L. cvs. Darab 14 and Yekta. Four weeks after sowing, plants were grown under soil moisture corresponding to 100, 75, 50 and 25 % field capacity for next four weeks. Fresh and dry masses, and total protein content in leaves and roots decreased obviously under drought. However, several new proteins appeared and content of some proteins was affected. Measurement of malondialdehyde content in leaves and roots showed that lipid peroxidation was lower in Yekta than in Darab 14. Severe stress increased SOD, POX, CAT and PPO activities in leaves and roots, especially in Yekta. According to the present study Yekta is more resistant to drought than Darab 14.Additional key words: catalase, malondialdehyde, peroxidase, polyphenol oxidase, Sesamum indicum, superoxide dismutase.

“…Drought increased protein content in RGS003. Changes in proteins can result from a variety of environmental stresses such as water stress (Yordanova et al 2004). Soluble proteins accumulation is also used as a Protein content means to increase plant tolerance against abiotic stresses (Ma and Turner 2006).…”

The effects of penconazole (PEN) and calcium (Ca 2?) on physiological and biochemical parameters were investigated in two canola cultivars (RGS003 and Sarigol) under water stress. Drought increased protein content in RGS003, but PEN, Ca 2? and PEN-Ca 2? treatment induced protein content in Sarigol. PEN, Ca 2? and PEN-Ca 2? treatment enhanced soluble sugar content in RGS003. In contrast to Sarigol, drought and PEN treatment induced total phenol content in RGS003. Flavonoid content increased by drought, but Ca 2? and PEN-Ca 2? treatment decreased it in both cultivars. Ca 2? and PEN-Ca 2? treatment enhanced tocopherol content in both cultivars under drought stress. Drought stress increased Phenylalanine ammonia-lyase (PAL) activity in Sarigol. PEN-Ca 2? treatment increased relative expression of PAL and its activity in RGS003. Fatty acid composition was modified by drought, PEN and Ca 2?. Saturated fatty acid (stearic acid) content declined but unsaturated fatty acid (oleic acid) content enhanced in both cultivars under drought. The application of PEN and Ca 2? decreased unsaturated fatty acids (linoleic and linolenic acid) in RGS003 under drought. According to our results, PEN and Ca 2? changed physiological and biochemical parameters and therefore these compounds are suggested for reduction of the negative effects of drought stress in canola.
