Epicuticular wax in plants limits non-stomatal water loss, inhibits postgenital organ fusion, protects plants against damage from UV radiation and imposes a physical barrier against pathogen infection. Here, we give a detailed description of the genetic, physiological and morphological consequences of a mutation in the rice gene WSL2, based on a comparison(More)

Rice MONOCULM 1 (MOC1) and its orthologues LS/LAS (lateral suppressor in tomato and Arabidopsis) are key promoting factors of shoot branching and tillering in higher plants. However, the molecular mechanisms regulating MOC1/LS/LAS have remained elusive. Here we show that the rice tiller enhancer (te) mutant displays a drastically increased tiller number. We(More)
Heading date is a key determinant of regional and seasonal adaptation in rice (Oryza sativa L.). A minor-effect quantitative trait locus (QTL), QTL for D ays t o h eading 12a (qDTH-12a), with unknown genetic action was previously coarsely detected in a recombinant inbred line population. The study reported here was designed to better define the qDTH-12a(More)
In this study, the pharmacological kinetics of Buthus martensi Karsch (BmK) AS, a specific modulator of voltage-gated sodium channel site 4, was investigated on Nav1.3 expressed in Xenopus oocytes. Two-electrode voltage clamp was used to record the whole-cell sodium current. The peak currents of Nav1.3 were depressed by BmK AS over a wide range of(More)
Bupivacaine ranks as the most potent and efficient drug among class I local anesthetics, but its high potential for toxic reactions severely limits its clinical use. Although bupivacaine-induced toxicity is mainly caused by substantial blockade of voltage-gated sodium channels (VGSCs), how these hydrophobic molecules interact with the receptor sites to(More)
Land plants have evolved increasingly complex regulatory modes of their flowering time (or heading date in crops). Rice (Oryza sativa L.) is a short-day plant that flowers more rapidly in short-day but delays under long-day conditions. Previous studies have shown that the CO-FT module initially identified in long-day plants (Arabidopsis) is evolutionary(More)
Chlorophyll (Chl) and lutein are the two most abundant and essential components in photosynthetic apparatus, and play critical roles in plant development. In this study, we characterized a rice mutant named young leaf chlorosis 1 (ylc1) from a 60Co-irradiated population. Young leaves of the ylc1 mutant showed decreased levels of Chl and lutein compared to(More)
MicroRNAs (miRNAs) modulate gene expression in different tissues and at diverse developmental stages, including grain development in japonica rice. To identify novel miRNAs in indica rice and to study their expression patterns during the entire grain filling process, small RNAs from all stages of grain development were sequenced and their expression(More)
An insert mutation of YELLOW - GREEN LEAF2 , encoding Heme Oxygenase 1 , results in significant reduction of its transcript levels, and therefore impairs chlorophyll biosynthesis in rice. Heme oxygenase (HO) in higher plants catalyzes the degradation of heme to synthesize phytochrome precursor and its roles conferring the photoperiodic control of flowering(More)
