The role of Pro-P5C Cycle in chs mutants of Arabidopsis under cold stress
Abstract Proline metabolism is implicated in plant responses to abiotic stresses, including the chilling stress. During proline catabolism, the two-step oxidation of proline is performed by the continuous actions of proline dehydrogenase (ProDH), which produces $ Δ^{1} $-pyrroline-5-carboxylate (P5C...

520 | |a Abstract Proline metabolism is implicated in plant responses to abiotic stresses, including the chilling stress. During proline catabolism, the two-step oxidation of proline is performed by the continuous actions of proline dehydrogenase (ProDH), which produces $ Δ^{1} $-pyrroline-5-carboxylate (P5C), and P5C dehydrogenase (P5CDH), which oxidizes P5C to glutamate. The Arabidopsis thaliana chilling mutants chs1 and chs2 are sensitive to chilling temperatures of 13–18°C. For a better understanding of Arabidopsis responses to chilling stress, 4-week-old wild-type (WT) and chs1 and chs2 lines, with three plants in each group, were subjected to chilling stress (13°C), cold stress (4°C), or remained under normal conditions (23°C); and several factors including the expression of ProDH2 and P5CDH genes, POX (peroxidase) and SOD (superoxide dismutase) activities, as well as MDA and proline contents were examined. Our results showed an increase in the proline content in all lines under chilling conditions. In addition, a greater expression of ProDH2 and a lower expression of P5CDH were observed, leading us to speculate a greater breakdown of proline into P5C and a consequent overproduction of ROS in the ETC cycle. The higher POX and SOD activities and a higher MDA content in chs mutants at 13°C are in line with this speculation. Finally, cold-treated plants (4°C) only showed an increase in proline levels. | ||

A. verfasserin aut The role of Pro-P5C Cycle in chs mutants of Arabidopsis under cold stress 2013 Text txt rdacontent Computermedien c rdamedia Online-Ressource cr rdacarrier Abstract Proline metabolism is implicated in plant responses to abiotic stresses, including the chilling stress. During proline catabolism, the two-step oxidation of proline is performed by the continuous actions of proline dehydrogenase (ProDH), which produces $ Δ^{1} $-pyrroline-5-carboxylate (P5C), and P5C dehydrogenase (P5CDH), which oxidizes P5C to glutamate. The Arabidopsis thaliana chilling mutants chs1 and chs2 are sensitive to chilling temperatures of 13–18°C. For a better understanding of Arabidopsis responses to chilling stress, 4-week-old wild-type (WT) and chs1 and chs2 lines, with three plants in each group, were subjected to chilling stress (13°C), cold stress (4°C), or remained under normal conditions (23°C); and several factors including the expression of ProDH2 and P5CDH genes, POX (peroxidase) and SOD (superoxide dismutase) activities, as well as MDA and proline contents were examined. Our results showed an increase in the proline content in all lines under chilling conditions. In addition, a greater expression of ProDH2 and a lower expression of P5CDH were observed, leading us to speculate a greater breakdown of proline into P5C and a consequent overproduction of ROS in the ETC cycle. The higher POX and SOD activities and a higher MDA content in chs mutants at 13°C are in line with this speculation.

During proline catabolism, the two-step oxidation of proline is performed by the continuous actions of proline dehydrogenase (ProDH), which produces $ Δ^{1} $-pyrroline-5-carboxylate (P5C), and P5C dehydrogenase (P5CDH), which oxidizes P5C to glutamate. The Arabidopsis thaliana chilling mutants chs1 and chs2 are sensitive to chilling temperatures of 13–18°C. For a better understanding of Arabidopsis responses to chilling stress, 4-week-old wild-type (WT) and chs1 and chs2 lines, with three plants in each group, were subjected to chilling stress (13°C), cold stress (4°C), or remained under normal conditions (23°C); and several factors including the expression of ProDH2 and P5CDH genes, POX (peroxidase) and SOD (superoxide dismutase) activities, as well as MDA and proline contents were examined. Our results showed an increase in the proline content in all lines under chilling conditions. In addition, a greater expression of ProDH2 and a lower expression of P5CDH were observed, leading us to speculate a greater breakdown of proline into P5C and a consequent overproduction of ROS in the ETC cycle. The higher POX and SOD activities and a higher MDA content in chs mutants at 13°C are in line with this speculation. Finally, cold-treated plants (4°C) only showed an increase in proline levels.</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">chilling-sensitive mutants</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">chilling stress</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">cold stress</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Pro-P5C cycle</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Shekaste Band, R.</subfield><subfield code="e">verfasserin</subfield><subfield code="4">aut</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Najafi, F.</subfield><subfield code="e">verfasserin</subfield><subfield code="4">aut</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Nabiuni, M.</subfield><subfield code="e">verfasserin</subfield><subfield code="4">aut</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Gharari, Z.</subfield><subfield code="e">verfasserin</subfield><subfield code="4">aut</subfield></datafield><datafield tag="773" ind1="0" ind2="8"><subfield code="i">Enthalten in</subfield><subfield code="t">Russian journal of plant physiology</subfield><subfield code="d">Moscow : MAIK Nauka/Interperiodica Publ., 1996</subfield><subfield code="g">60(2013), 3 vom: 22.

The role of Pro-P5C Cycle in chs mutants of Arabidopsis under cold stress |
abstract |
Abstract Proline metabolism is implicated in plant responses to abiotic stresses, including the chilling stress. During proline catabolism, the two-step oxidation of proline is performed by the continuous actions of proline dehydrogenase (ProDH), which produces $ Δ^{1} $-pyrroline-5-carboxylate (P5C), and P5C dehydrogenase (P5CDH), which oxidizes P5C to glutamate. The Arabidopsis thaliana chilling mutants chs1 and chs2 are sensitive to chilling temperatures of 13–18°C. For a better understanding of Arabidopsis responses to chilling stress, 4-week-old wild-type (WT) and chs1 and chs2 lines, with three plants in each group, were subjected to chilling stress (13°C), cold stress (4°C), or remained under normal conditions (23°C); and several factors including the expression of ProDH2 and P5CDH genes, POX (peroxidase) and SOD (superoxide dismutase) activities, as well as MDA and proline contents were examined. Our results showed an increase in the proline content in all lines under chilling conditions. In addition, a greater expression of ProDH2 and a lower expression of P5CDH were observed, leading us to speculate a greater breakdown of proline into P5C and a consequent overproduction of ROS in the ETC cycle. The higher POX and SOD activities and a higher MDA content in chs mutants at 13°C are in line with this speculation. Finally, cold-treated plants (4°C) only showed an increase in proline levels. |
