Phenylpropanoids including diverse compounds, such as monolignols and hydroxycinnamic acids (HCAAs), are essential for land plants to protect them against abiotic stresses, and create physical and chemical barriers to pathogen infection. However, the production control of these compounds against to pathogens has been poorly understood. Previously we showed that a MAMP (microbe-associated molecular pattern) -responsive MAPK (mitogen-activated protein kinase) cascade (MKK4-MPK3/MPK6) comprehensively induced the expression of cinnamate/monolignol synthesis genes in rice cells...

Summary: The evolutionary histories of individual regions across a genomic alignment - called 'local genealogies' - can differ from each other, due to processes such as recombination. Elucidating and analyzing these local genealogies are important for a large number of inference tasks, including those pertaining to species phylogenies, evolutionary processes, and trait mapping. In this paper, we present a toolkit for automated local phylogenomic analyses, or ALPHA. The purpose of this toolkit is to provide a wide array of functionalities for automated inference of local genealogies as well as analyses based on these local genealogies...

Background: Abscisic acid (ABA) is a well-studied phytohormone demonstrated to be involved in sub-sets of stress responses in plants, such as iron (Fe) deficiency and phosphorus (P) deficiency in Arabidopsis. However, whether ABA is involved in P deficiency in rice has not been frequently studied. The present study was undertaken to investigate the mechanism underlying ABA-aggravated P deficiency in rice (Oryza sativa). Results: P deficiency decreased ABA accumulation rapidly (within 1 h) in the roots...

Reducing Cd accumulation in the rice grain is an important issue for human health. The aim of this study is to manipulate both expression and tissue localization of OsHMA3, a tonoplast-localized Cd transporter in the roots by expressing it under the control of OsHMA2 promoter, which shows high expression in different organs including roots, nodes and shoots. In two independent transgenic lines, the expression of OsHMA3 was significantly enhanced in all organs compared with the non-transgenic rice. Furthermore, OsHMA3 protein was detected in the root pericycle cells and phloem region of both the diffuse vascular bundle and the enlarged vascular bundle of the nodes...

In flowering plants, various RNA editing events occur in the mitochondria and chloroplasts as part of post-transcriptional processes. Although several PPRs and MORFs have been identified as RNA editing factors, the underlying mechanism of PPRs and the cooperation among these proteins are still obscure. Here, we identified a rice dual-localized PPR protein, OsPGL1. The loss of function of OsPGL1 resulted in defects in both chloroplast RNA editing of ndhD-878 and mitochondrial RNA editing of ccmFc-543, both of which could be restored via complementary validation...

The endogenous life cycle of Eimeria caliginosa was studied in experimentally-infected dusky rice rats, Melanomys caliginosus. All endogenous stages were located in the epithelial cells of villi in the small intestine. Both Giemsa-stained mucosal scrapings and histological sections were studied for the diagnosis of all the life cycle stages. Eimeria caliginosa has 3 generations of meronts (M) that differ by size, shape, and number of merozoites (m), which also differ in their size, shape, and location of their nuclei within the cytoplasm of the meronts...

Hydrogen sulfide (H2 S) plays a vital role in Al3+ stress resistance in plants, but the underlying mechanism is unclear. In the present study, pretreatment with 2 μM of the H2 S donor NaHS significantly alleviated the inhibition of root elongation caused by Al toxicity in rice roots, which was accompanied by a decrease in Al contents in root tips under 50 μM Al3+ treatment. NaHS pretreatment decreased the negative charge in cell walls by reducing the activity of pectin methylesterase and decreasing the pectin and hemicellulose contents in rice roots...

Mechanisms underlying plant non-host resistance to Xanthomonas oryzae pv. oryzicola ( Xoc ), the pathogen causing rice leaf streak disease, are largely unknown. Cyclic nucleotide-gated ion channels (CNGCs) are calcium-permeable channels that are involved in various biological processes including plant resistance. In this study, functions of two tomato CNGC genes SlCNGC1 and SlCNGC14 in non-host resistance to Xoc were analyzed. Silencing of SlCNGC1 and SlCNGC14 in tomato significantly enhanced Xoc -induced hypersensitive response (HR) and non-host resistance, demonstrating that both SlCNGC1 and SlCNGC14 negatively regulate non-host resistance related HR and non-host resistance to Xoc in tomato...

Although abscisic acid (ABA) is an important hormone that regulates seed dormancy, stomatal closure, plant development, as well as responses to environmental stimuli, the physiological mechanisms of ABA response to multiple stress in rice remain poorly understood. In the ABA biosynthetic pathway, 9- cis -epoxycarotenoid dioxygenase (NCED) is the key rate-limiting enzyme. Here, we report important functions of OsNCED3 in multi-abiotic stress tolerance in rice. The OsNCED3 is constitutively expressed in various tissues under normal condition, Its expression is highly induced by NaCl, PEG, and H2 O2 stress, suggesting the roles for OsNCED3 in response to the multi-abiotic stress tolerance in rice...

This study investigated the regulatory role of exogenous salicylic acid (SA) in rice and its effects on toxic reactive oxygen and nitrogen species during short-term salinity stress. SA application (0.5 and 1.0 mM) during salinity-induced stress (100 mM NaCl) resulted in significantly longer shoot length and higher chlorophyll and biomass accumulation than with salinity stress alone. NaCl-induced reactive oxygen species production led to increased levels of lipid peroxidation in rice plants, which were significantly reduced following SA application...

Plants have a non-energy conserving bypass of the classical mitochondrial cytochrome c pathway, known as the alternative respiratory pathway (AP). This involves type II NAD(P)H dehydrogenases (NDs) on both sides of the mitochondrial inner membrane, ubiquinone, and the alternative oxidase (AOX). The AP components have been widely characterised from Arabidopsis, but little is known for monocot species. We have identified all the genes encoding components of the AP in rice and barley and found the key genes which respond to oxidative stress conditions...
