Nfu-type proteins are essential in the biogenesis of iron–sulfur (Fe-S) clusters numerous organisms. A number phenotypes including low levels Fe-S cluster incorporation associated with deletion gene encoding a chloroplast-specific protein, Nfu2 from Arabidopsis thaliana (AtNfu2). Here, we report that recombinant AtNfu2 is able to assemble both [2Fe-2S] and [4Fe-4S] clusters. Analytical data gel filtration studies support cluster/protein stoichiometries one cluster/homotetramer...
We investigated heat shock (HS)-triggered Ca(2+) signalling transduced by a sensor, calmodulin (CaM), linked to early transcriptome changes of HS-responsive genes in rice. observed biphasic [Ca(2+) ](cyt) signature root cells that was distinct from epicotyl and leaf cells, which showed monophasic response after HS. Treatment with A23187 generated an intense sustained increase Conversely, treatment chelator, L-type channel blocker CaM antagonist, but not intracellular release inhibitor,...
Pectin, a major component of the primary cell wall, is synthesized in Golgi apparatus and exported to wall highly methylesterified form, then partially demethylesterified by pectin methylesterases (PMEs; EC 3.1.1.11). PME activity on status methylesterification profoundly affects properties and, thereby, critical for plant development defense response, although roles PMEs under heat stress (HS) are poorly understood. Functional genome annotation predicts that at least 66 potential genes...
The adaptation of Rice yellow mottle virus (RYMV) to recessive resistance mediated by the rymv1-2 allele has been reported as a model study emergence and evolution virulent variants. virulence factors have identified eukaryotic translation initiation factor eIF(iso)4G1 viral genome-linked protein (VPg), respectively, but molecular mechanisms involved in their interaction are still unknown. In this study, we demonstrated direct between RYMV VPg central domain rice both vitro, using...
Apoplastic Ca(2+) concentration controls membrane permeability, cell wall stabilization, and integrity; however, little is known about its role in thermotolerance plants. Here, we report that the acquired of etiolated rice seedlings (Oryza sativa) was abolished by an exogenously supplied chelator, EGTA, related to increased cellular content leakage during heat shock (HS) treatment. Thermotolerance restored addition EGTA incubation. Pectin methylesterase (EC 3.1.1.11), a cell-wall remodeling...
Synthesis of heat shock proteins (HSPs) in response to (HS) is essential for thermotolerance. The effect a Ca2+ chelator, EGTA, was investigated before lethal HS treatment soybean (Glycine max) seedlings with acquired thermotolerance induced by preheating. Such became non-thermotolerant EGTA treatment. addition Ca2+, Sr2+ or Ba2+ the EGTA-treated samples rescued from death preventing increased cellular leakage electrolytes, amino acids, and sugars caused EGTA. It confirmed that did not...
Numerous proteins require a metallic co-factor for their function. In plastids, the maturation of iron-sulfur (Fe-S) necessitates complex assembly machinery. this study, we focused on Arabidopsis thaliana NFU1, NFU2, and NFU3, which participate in final steps process. According to strong photosynthetic defects observed high chlorophyll fluorescence 101 (hcf101), nfu2, nfu3 plants, determined that NFU2 but not act immediately upstream HCF101 [Fe4S4]-containing photosystem I subunits. An...
Pectin is a major component of the plant cell wall, forming network that contributes to wall integrity and flexibility. methylesterase (PME) catalyzes removal methylester groups from homogalacturonan backbone, most abundant pectic polymer, intercellular adhesion during development different environmental stimuli stress. In this study, we identified characterized an Arabidopsis type-II PME, PME53, which encodes deposited protein may be involved in stomatal lineage pathway functions. We...
The Ca2+/calmodulin (CaM) signaling pathway mediates the heat stress (HS) response and acquisition of thermotolerance in plants. We showed that rice CaM1-1 isoform can interpret a Ca2+ signature difference amplitude, frequency, temporal–spatial properties regulating transcription nucleoplasmic small heat-shock protein gene (sHSPC/N) during HS. A23187 treatments under HS generated an intense sustained increase [Ca2+]cyt accelerated expression sHSPC/N genes, which suggests HS-induced...
Abstract Alternaria cosmosa and patula are seed‐borne pathogens of Cosmos sulfurous Cav. (yellow cosmos) Tagetes L. (French marigold), respectively. Bacterial strains were isolated from the two hosts to compare their potential control species with provided by fungicides, prochloraz pyrifenox. Eight 73 (11%) C. four 128 (3%) T. found be effective antagonists in vitro screening. The efficacy these active as was evaluated laboratory, glasshouse field experiments. most strains, Cb 6 strain TpE 1...
Alternaria patula , the cause of French marigold leaf black spot and flower blight, was first isolated from seeds cv. Queen Sophia. It is described as a new species has considerable morphological variation with preferential pathogenicity to Asteraceae, Solanaceae Cucurbitaceae plants. produces an array pectin depolymerases that can break 1,4‐α‐glycosidic bonds either by hydrolysis polygalacturonases ( PG E.C. 3.2.1.15) or via trans ‐elimination pectate lyases PL 4.2.2.2) PNL 4.2.2.10).
