Key message
- The antisense expression of OsNPR1 (as-npr1), which reduced the expression of the gene by 50%, increased elicited levels of JA and ethylene (ET) as well as of expression of a lipoxygenase gene OsHI-LOX and an ACC synthase gene OsACS2
- Antisense expression of OsPLDalpha4 and -alpha5 (as-pld), which resulted in a 50% reduction of the expression of the two genes, reduced elicited levels of linolenic acid, JA, green leaf volatiles, and ethylene and attenuated the SSB-induced expression of a mitogen-activated protein kinase (OsMPK3), a lipoxygenase (OsHI-LOX), a hydroperoxide lyase (OsHPL3), as well as a 1-aminocyclopropane-1-carboxylic acid synthase (OsACS2)
- These findings suggest the importance of ET biosynthesis and, consequently, the coproduct, cyanide, for HR-accompanied resistance to blast fungus in young rice plants and the contribution of induced OsACS2 and OsACO7 gene expression to it
Connection
- OsACO2, OsACS2, EAR motif mutation of rice OsERF3 alters the regulation of ethylene biosynthesis and drought tolerance, Consistent with our previous research, the expression of ethylene synthesis genes, including ACO2, ACS2, and ACS6 was down-regulated in OE lines
- AP37~OsERF3, OsACS2, EAR motif mutation of rice OsERF3 alters the regulation of ethylene biosynthesis and drought tolerance, Specifically, ACS2 was up-regulated in mEAR lines compared with that in OE lines and WT plants, suggesting that the Leu/Ala substitution within the EAR motif resulted in loss of repression of OsERF3
- OsACS2, OsACS6~SSG6, EAR motif mutation of rice OsERF3 alters the regulation of ethylene biosynthesis and drought tolerance, Consistent with our previous research, the expression of ethylene synthesis genes, including ACO2, ACS2, and ACS6 was down-regulated in OE lines
- OsACS1~OsASC1, OsACS2, Expression characteristics of OS-ACS1 and OS-ACS2, two members of the 1-aminocyclopropane-1-carboxylate synthase gene family in rice Oryza sativa L. cv. Habiganj Aman II during partial submergence, Herein we have studied the expression characteristics of two members of the five-member multigene family encoding ACC synthase in rice OS-ACS1 and OS-ACS2 and show that partial submergence induces expression of OS-ACS1 and suppresses expression of OS-ACS2

Habiganj Aman II during partial submergence, Expression characteristics of OS-ACS1 and OS-ACS2, two members of the 1-aminocyclopropane-1-carboxylate synthase gene family in rice (Oryza sativa L. cv. Habiganj Aman II) during partial submergence
- OsACS2, OsHI-LOX~OsLOX9, The chloroplast-localized phospholipases D alpha4 and alpha5 regulate herbivore-induced direct and indirect defenses in rice, Antisense expression of OsPLDalpha4 and -alpha5 (as-pld), which resulted in a 50% reduction of the expression of the two genes, reduced elicited levels of linolenic acid, JA, green leaf volatiles, and ethylene and attenuated the SSB-induced expression of a mitogen-activated protein kinase (OsMPK3), a lipoxygenase (OsHI-LOX), a hydroperoxide lyase (OsHPL3), as well as a 1-aminocyclopropane-1-carboxylic acid synthase (OsACS2)

- OsACO7, OsACS2, Contribution of ethylene biosynthesis for resistance to blast fungus infection in young rice plants, Among six ACC synthase (ACS) and seven ACO genes found in the rice genome, OsACS2 was transiently expressed at 48 hpi in IL7 and at 96 hpi in wild type, and OsACO7 was expressed at 48 hpi in IL7
- OsACO7, OsACS2, Contribution of ethylene biosynthesis for resistance to blast fungus infection in young rice plants, These findings suggest the importance of ET biosynthesis and, consequently, the coproduct, cyanide, for HR-accompanied resistance to blast fungus in young rice plants and the contribution of induced OsACS2 and OsACO7 gene expression to it
- OsACS2, OsHI-LOX~OsLOX9, OsNPR1 negatively regulates herbivore-induced JA and ethylene signaling and plant resistance to a chewing herbivore in rice, The antisense expression of OsNPR1 (as-npr1), which reduced the expression of the gene by 50%, increased elicited levels of JA and ethylene (ET) as well as of expression of a lipoxygenase gene OsHI-LOX and an ACC synthase gene OsACS2
- OsACS2, OsNPR1~NH1, OsNPR1 negatively regulates herbivore-induced JA and ethylene signaling and plant resistance to a chewing herbivore in rice, The antisense expression of OsNPR1 (as-npr1), which reduced the expression of the gene by 50%, increased elicited levels of JA and ethylene (ET) as well as of expression of a lipoxygenase gene OsHI-LOX and an ACC synthase gene OsACS2
- OsACS2, OsETOL1, A homolog of ETHYLENE OVERPRODUCER, OsETOL1, differentially modulates drought and submergence tolerance in rice, OsETOL1 was found to interact with OsACS2, a homolog of 1-amino-cyclopropane-1-carboxylate (ACC) synthase (ACS), which acts as a rate-limiting enzyme for ethylene biosynthesis.
