In vitro assay for ABA 8'-hydroxylase: implications for improved assays for cytochrome P450 enzymes.
Joan E Krochko et al.
Methods in molecular biology (Clifton, N.J.), 773, 113-134 (2011-09-08)
In vitro assays for cytochrome P450 enzymes developed from plant-derived microsomal extracts have not been used extensively for the characterization and quantification of enzyme activities in plant tissues. We describe here an in vitro assay for abscisic acid (ABA) 8'-hydroxylase

Autophagy, 15(3), 407-422 (2018-09-14)
Glucose produced from photosynthesis is a key nutrient signal regulating root meristem activity in plants; however, the underlying mechanisms remain poorly understood. Here, we show that, by modulating reactive oxygen species (ROS) levels, the conserved macroautophagy/autophagy degradation pathway contributes to

Three vitrification-based methods for the cryopreservation of Grammatophyllum speciosum protocorms were invesigated: droplet-vitrification, encapsulation-dehydration and encapsulation-vitrification. Protocorms, 0.1 cm in diameter, developed from 2-month-old germinating seeds were used. For droplet-vitrification, protocorms were precultured on filter paper soaked in half strength

HKT1;5 loci/alleles are important determinants of crop salinity tolerance. HKT1;5s encode plasmalemma-localized Na+ transporters, which move xylem Na+ into xylem parenchyma cells, reducing shoot Na+ accumulation. Allelic variation in rice OsHKT1;5 sequence in specific landraces (Nona Bokra OsHKT1;5-NB/Nipponbare OsHKT1;5-Ni) correlates

Calmodulin (CaM) regulates plant disease responses through its downstream calmodulin-binding proteins (CaMBPs) often by affecting the biosynthesis or signaling of phytohormones, such as jasmonic acid (JA) and salicylic acid. However, how these CaMBPs mediate plant hormones and other stress resistance-related

Arabidopsis LONG-CHAIN BASE KINASE 1 (LCBK1) interacts with MEDEA, a component of PCR2 complex that negatively regulates immunity. LCBK1 phosphorylates phytosphingosine and thereby promotes stomatal immunity against bacterial pathogens. Arabidopsis polycomb-group repressor complex2 (PRC2) protein MEDEA (MEA) suppresses both pattern-triggered
