Isoprene is the most important nonmethane hydrocarbon emitted by plants. The role of isoprene in the plant is not entirely understood but there is evidence that it might have a protective role against different oxidative stresses originating from heat shock and/or exposure to ozone (O(3)). Thus, plants under stress conditions might benefit by constitutively high or by higher stress-induced isop...

Karrikins are a group of chemicals found in plant-derived smoke from burning plant material. Till now, scientists concentrated on their effect seed germination plants sensitive to smoke. However, there reports the karrikins physiology and morphology which do not occur fire areas naturally treated by These positively affect biometric parameters vitro cultured plants. Recently, rate pollen severa...

in this work, the effects of silicon (si) supplementation were studied in pistachio (pistacia veral. cv ahmadaghaii) plants exposed to high salinity stress. plants were grown in pots undercontrol and salt (ec=15 ds m-1) conditions without or with si treatment (0.35 g na2sio3 kg-1soil) under field conditions. salt stress reduced the plants’ growth significantly in both –si and+si plants; however...

A gene encoding a temperature-sensitive mutant (MPP154A) of the 30-kilodalton movement protein (MP) of tobacco mosaic virus (TMV) was transformed into Nicotiana tabacum cv Xanthi. Transgenic plants expressing the MPP154A gene complemented local and systemic movement of an MP-defective mutant of TMV (U3/12MPfs) at the permissive temperature of 24 degrees C but not at 32 degrees C, the nonpermiss...

S u m m a r y : The response of 11 grapevine rootstock varieties to increasing salt concentrations (0, 50, 85, 120, 155 mMNaCI) was studied under in vitro and growth chamber conditions . The effect of salinity on the mortality of explants was compared with that of plantlets grown under growth chamber conditions and with data in literature on rootstock resistance under field conditions . In addi...

in order to study of the effect of priming and salinity on physiological and chemical characteristics of wheat(triticum aestivum l.), an experiment was carried out at the experimental farm of shiraz university. results showedthat primed plants significantly reduced its gas exchanges by accelerating senescence under a series of salt stress,which became more serious along with the increasing of s...

Climate change-related events, such as marine heatwaves, are increasing seawater temperatures, thereby putting pressure on biota. The cosmopolitan distribution and significant contribution to primary production by the genus Ruppia makes them interesting organisms study thermal tolerance local adaptation. In this study, we investigated photosynthetic responses in predicted future warming two con...

As a dehydrin belonging to group II late embryogenesis abundant protein (LEA) family, Arabidopsis Low Temperature-Induced 30 (LTI30)/XERO2 has been shown to be involved in plant freezing stress resistance. However, the other roles of AtLTI30 remain unknown. In this study, we found that the expression of AtLTI30 was largely induced by drought stress and abscisic acid (ABA) treatments. Thereafter...
