Arabidopsis CYP94B3 encodes jasmonyl-L-isoleucine 12-hydroxylase, a key enzyme in the oxidative catabolism of jasmonate.
The kinetics of wound-induced accumulation of 12-hydroxyJA-Ile in plants were examined, and its involvement in the plant wound response is described, demonstrating that CYP94B3 plays a major regulatory role in controlling the level of JA-Iel in plants. Expand
The Arabidopsis gene CAD1 controls programmed cell death in the plant immune system and encodes a protein containing a MACPF domain.
It is concluded that the CAD1 protein negatively controls the SA-mediated pathway of programmed cell death in plant immunity. Expand
OsJAR1 and OsJAR2 are jasmonyl-L-isoleucine synthases involved in wound- and pathogen-induced jasmonic acid signalling.
The data suggest that these two JA-Ile synthases are differentially involved in the activation of JA signalling in response to wounding and pathogen challenge in rice. Expand
Isolation of pseudoprototimosaponin AIII from rhizomes of Anemarrhena asphodeloides and its hypoglycemic activity in streptozotocin-induced diabetic mice.
A hot-H2O extract of rhizomes of Anemarrhena asphodeloides, the Japanese sino-medicine "chimo," lowered the blood glucose level in alloxan-diabetic mice, suggesting that the hypoglycemic mechanism may be due to inhibition of hepatic gluconeogenesis and/or glycogenolysis. Expand
Temporal trends of perfluoroalkyl acids in plasma samples of pregnant women in Hokkaido, Japan, 2003-2011.
Levels of prenatal exposure to PFAA between 2003 and 2011 in Hokkaido, Japan, are characterized by measuring PFAA concentrations in plasma samples from pregnant women using simultaneous analysis by ultra-performance liquid chromatography coupled to triple quadrupole tandem mass spectrometry. Expand

In vitro antifungal antitumor cytotoxicity and blood coagulability effects of steroid saponins from garlic and related Allium species are provided and animal studies on the cholesterol-lowering effects of the saponin fractions from garlic are summarized. Expand
Genome-wide analyses of early translational responses to elevated temperature and high salinity in Arabidopsis thaliana.
The results highlight the importance of dynamic changes in mRNA translation, which include selective translation and extensive repression of a subset of transcripts, in plant abiotic stress responses. Expand
Antifungal activity of ajoene derived from garlic
The antifungal activity of six fractions derived from garlic was investigated in an in vitro system. Ajoene had the strongest activity in these fractions. The growth of both Aspergillus niger andExpand
Endoplasmic Reticulum-associated Inactivation of the Hormone Jasmonoyl-l-Isoleucine by Multiple Members of the Cytochrome P450 94 Family in Arabidopsis*
The results provide an integrated view of how multiple ER-localized CYP94 and JA amidohydrolase enzymes attenuate JA signaling during stress responses and report that a third member (CYP94B1) of the CYP 94 family also participates in oxidative turnover of JA-Ile in Arabidopsis. Expand
Resistant and susceptible responses in tomato to cyst nematode are differentially regulated by salicylic acid.
It is found that PR-1(P4) was a hallmark for the cultivar resistance conferred by Hero A against PCN and that nematode parasitism resulted in the inhibition of the SA signaling pathway in the susceptible cultivars. Expand
