Photosynthetic organisms adapt to changes in light quality by redistributing excitation energy between two photosystems through state transition. This reorganization of antenna systems leads an enhanced photosynthetic yield. Using a genetic approach Chlamydomonas reinhardtii dissect the signal transduction pathway transition, we identified chloroplast thylakoid-associated serine-threonine protein kinase, Stt7, that has homologs land plants. Stt7 is required for phosphorylation major...
The root knot nematode, Meloidogyne incognita, is an obligate parasite that causes significant damage to a broad range of host plants. Infection associated with secretion proteins surrounded by proliferating cells. Many parasites are known secrete effectors interfere plant innate immunity, enabling infection occur; they can also release pathogen-associated molecular patterns (PAMPs, e.g., flagellin) trigger basal immunity through the nematode stylet into cell. This leads suppression and...
The chloroplast Albino3 (Alb3) protein is a homolog of the mitochondrial Oxa1p and YidC proteins Escherichia coli, which are essential components for integrating membrane proteins. In vitro studies in vascular plants have revealed that Alb3 required integration light-harvesting complex into thylakoid membrane. Here, we show gene affected ac29 mutant Chlamydomonas reinhardtii Alb3.1. availability has allowed us to examine function Alb3.1 vivo. loss two major effects. First, amount from...
The root-knot nematode, Meloidogyne graminicola , can cause substantial rice yield losses. Understanding the mechanisms of resistance to this nematode species in known resistant genotypes may help improve genotypes, aiming at developing and implementing environment-friendly cost-effective management strategies. Using susceptible a comparative analysis histological response was made during two phases colonisation: i ) root penetration; ii subsequent establishment development by M....
Abstract Background Plant-parasitic nematodes developed strategies to invade and colonize their host plants, including expression of immune suppressors overcome defenses. Meloidogyne graminicola M. incognita are root-knot nematode (RKN) species reported damage rice ( Oryza sativa L.) cultivated in upland irrigated systems. Despite wide range, study the molecular plant - RKN interaction has been so far limited a few dicotyledonous model plants. The aim this was investigate if cv. Nipponbare...
Meloidogyne graminicola ( Mg ), commonly known as the rice root-knot nematode, is a highly destructive pest that inflicts significant damage on crops worldwide. thought to reproduce primarily by meiotic parthenogenesis, but its success across diverse habitats and hosts raises important questions about adaptation mechanisms, particularly those driving evolution of virulence. Documenting origin pathogen, reproductive strategies other evolutionary processes shaping genome are thus crucial...
We have compared the seed production of Arabidopsis wild‐type and mutant plants impaired in regulation photosynthetic light reactions grown under natural conditions field. Mutant ( npq4 ) lacking feedback de‐excitation were, as previously demonstrated, severely affected production. Seed sets deficient state transitions stn7 were 19% smaller than those plants, whereas missing STN8 kinase required for phosphorylation core photosystem II reaction centre polypeptides stn8 had a normal Plants...
Due to their sessile life style, plant survival is dependent on the ability build up fast and highly adapted responses environmental stresses by modulating defense response organ growth. The phytohormone jasmonate plays an essential role in regulating these stress. To assess variation of growth identify genetic determinants associated JA treatment, we conducted a genome-wide association study (GWAS) using original panel Vietnamese rice accessions. phenotyping results showed high natural...
Abstract Discovered in the 1960s, Meloidogyne graminicola is a root‐knot nematode species considered as major threat to rice production. Yet, its origin, genomic structure, and intraspecific diversity are poorly understood. So far, such studies have been limited by unavailability of sufficiently complete well‐assembled genome. In this study, using combination Oxford Nanopore Technologies Illumina sequencing data, we generated highly contiguous reference genome (283 scaffolds with an N50...
Meloidogyne graminicola is a major plant-parasitic nematode affecting rice cultivation in Asia. Resistance to this was found the African genotypes Oryza glaberrima and O. longistaminata; however, due interspecific hybrid sterility, introgression of resistance genes widely consumed sativa varieties remains challenging. Recently, and, here, we report for first time histological genetic characterization M. Zhonghua 11, an variety. Bright-light microscopy fluorescence observations root tissue...
Introduction Rice ( Oryza sativa ) is a staple food worldwide, but its production under constant pressure from both abiotic and biotic stresses, resulting in high use of agrochemicals. The plant microbiome harbours microorganisms that can benefit health provide alternatives to the composition microbiomes depends on many factors (soil composition, age, health) considered primary driver future health. To identify protect against disease, we hypothesised asymptomatic rice plants fields pathogen...
Meloidogyne graminicola is a facultative meiotic parthenogenetic root-knot nematode (RKN) that seriously threatens agriculture worldwide. We have little understanding of its origin, genomic structure, and intraspecific diversity. Such information would offer better knowledge how this successfully damages rice in many different environments. Previous studies on nuclear ribosomal DNA (nrDNA) suggested close phylogenetic relationship between M. oryzae, despite their modes reproduction...
Meloidogyne graminicola, also known as the rice root-knot nematode, is one of most damaging plant-parasitic especially on rice. This obligate soilborne parasite induces formation galls that disturb root morphology and physiology. Its impact microbiome still not well described. Here, we conducted a survey in Northern Vietnam where collected infected (with galls) non-infected tips from same plants three naturally infested fields. Using metabarcoding approach, discovered M. graminicola...
Abstract Rice production in Southeast Asia is significantly affected by root-parasitic nematodes (RPN). The Green Revolution has encouraged new agricultural practices (e.g. intensive monoculture, high yielding rice variety) to respond the demand; however, these methods have promoted spread of pests. recent banning chemical nematicides resulted a need for alternative sustainable control strategies. In present study, we assessed effects direct-seeding mulch-based cropping system (DMC) vs...
Meloidogyne graminicola is a widely spread nematode pest of rice that reduces crop yield up to 20% on average in Asia, with devastating consequences for local and global production. Due the ban many chemical nematicides recent changes water management practices agriculture, an even greater impact M. can be expected future, stressing demand development new sustainable solutions. Recently, source resistance was identified Oryza sativa japonica variety Zhonghua 11 (Zh11). In present study, we...
