Crosstalk between phytohormone pathways is essential in plant growth, development and stress responses. Brassinosteroids (BRs) ethylene are both pivotal growth regulators, the interaction these two phytohormones tomato response to salt still unclear. Here, we explored mechanism by which BRs affect biosynthesis signaling seedlings under stress. The activity of 1-aminocyclopropane-1-carboxylate synthase (ACS), an synthesis enzyme, pathway were activated plants pretreated with BRs. Scavenging...
Mitochondrial alternative oxidase (AOX) is involved in a large number of plant physiological processes, such as growth, development and stress responses; however, the exact role AOX response to drought remains unclear. In our study, we provide solid evidences that activated capacity positively ethylene-induced tolerance, tomato (Solanum lycopersicum), accompanied by changing level hydrogen peroxide (H2 O2 ) autophagy. AOX1a-RNAi plants, tolerance was aggravated associated with decreasing The...
Effects of brassinosteroids (BRs) on cucumber (Cucumis sativus L.) abiotic stresses resistance to salt, polyethylene glycol (PEG), cold and the potential mechanisms were investigated in this work. Previous reports have indicated that BRs can induce ethylene production enhance alternative oxidase (AOX) pathway. The whether is involved as a signal molecule which connected BR with AOX regulating stress tolerance are still unknown. Here, we found pretreatment 1 µM brassinolide (BL, most active...
Summary Brassinosteroids ( BR s) play essential roles in modulating plant growth, development and stress responses. Here, involvement of s systemic resistance to virus was studied. Treatment local leaves Nicotiana benthamiana with induced upper untreated leaves, accompanied by accumulations H 2 O NO . Scavenging or blocked ‐induced resistance. accumulation pharmacological inhibition NADPH oxidase silencing respiratory burst homolog gene Nb RBOHB , but not RBOHA silencing. Silencing the...
Abstract Plant steroid hormones, brassinosteroids (BRs), play essential roles in plant growth, development and stress responses. However, mechanisms by which BRs interfere with resistance to virus remain largely unclear. In this study, we used pharmacological genetic approaches combination infection experiments investigate the role of defense against Tobacco Mosaic Virus (TMV) Nicotiana benthamiana . Exogenous applied enhanced infection, while application Bikinin (inhibitor glycogen synthase...
Brassinosteroids (BRs), plant steroid hormones, play essential roles in modulating cell elongation, vascular differentiation, senescence, and stress responses. However, the mechanisms by which BRs regulate mitochondria resistance to abiotic remain largely unclear. Mitochondrial alternative oxidase (AOX) is involved response a variety of environmental stresses. In this report, role AOX BR-induced tolerance against cold, polyethylene glycol (PEG), high-light stresses was investigated....
The spindle assembly checkpoint (SAC) ensures faithful chromosome segregation during cell division by monitoring kinetochore-microtubule attachment. Plants produce both sequence-conserved and diverged SAC components, it has been largely unknown how activation leads to the of these proteins at unattached kinetochores prevent cells from entering anaphase. In Arabidopsis thaliana , noncanonical BUB3.3 protein was detected throughout mitosis, unlike MAD1 plant-specific BUB1/MAD3 family BMF3 that...
Abstract The α-Aurora kinase is a crucial regulator of spindle microtubule organization during mitosis in plants. Here, we report post-mitotic role for reorganizing the phragmoplast array. In Arabidopsis thaliana , relocated from poles to midzone, where it interacted with cross-linker MAP65-3. hypomorphic mutant, MAP65-3 was detected on microtubules, followed by diffuse association pattern across midzone. Simultaneously, microtubules remained belatedly solid disk array before transitioning...
The evolutionarily conserved MAP65 family proteins bundle anti-parallel microtubules (MTs). In Arabidopsis thaliana, mutations in the MAP65-3 gene lead to serious defects MT organization phragmoplast and cause failures cytokinesis. However, functions of other ArabidopsisMAP65 isoforms are largely unknown. were analyzed based on genetic interactions among different map65 mutations. Live-cell imaging immunolocalization experiments revealed dynamic activities two closely related dividing cells....
The kinetochore scaffold 1 (KNL1) protein recruits spindle assembly checkpoint (SAC) proteins to ensure accurate chromosome segregation during mitosis. Despite such a conserved function among eukaryotic organisms, its molecular architectures have rapidly evolved so that the functional mode of plant KNL1 is largely unknown. To understand how SAC signaling regulated at kinetochores, we characterized gene in Arabidopsis thaliana . was detected kinetochores throughout mitotic cell cycle, and...
Recent studies reported that brassinosteroids (BRs) can induce plant tolerance to different environmental stresses via the nitric oxide (NO) signaling pathway. Previous reports have indicated alternative oxidase (AOX) plays an important role in plants under various stresses. The mechanisms governing how NO is involved as a signal molecule which connects BR with AOX regulating stress are still unknown. Recently, we found Nicotiana benthamiana seedlings were pretreated more salt stress,...
Brassinosteroids (BRs) are growth-promoting plant hormones that play a crucial role in biotic stress responses. Here, we found BR treatment increased nitric oxide (NO) accumulation, and significant reduction of virus accumulation Arabidopsis thaliana. However, the plants pre-treated with NO scavenger [2-(4-carboxyphenyl)-4,4,5,5-tetramethyl-imidazoline-1-1-oxyl-3-oxide (PTIO)] or nitrate reductase (NR) inhibitor (tungstate) hardly had any generation appeared to have highest viral replication...
Proper chromosome segregation during cell division is essential for genomic integrity and organismal development. This process monitored by the spindle assembly checkpoint (SAC), which delays anaphase onset until all chromosomes are properly attached to mitotic spindle. The kinetochore protein KNL1 plays a critical role in recruiting SAC proteins. Here, we reveal that Arabidopsis regulates silencing through direct recruitment of type one phosphatase (TOPP) kinetochores. We show interacts...
Abstract Spindle assembly in vertebrates requires the Aurora kinase, which is targeted to microtubules and activated by TPX2 (Targeting Protein of XKLP2). In Arabidopsis (Arabidopsis thaliana), TPX2-LIKE 3 (TPXL3), but not highly conserved TPX2, essential. To test hypothesis that TPXL3 regulates function α kinase spindle assembly, we generated transgenic lines expressing an artificial microRNA targeting mRNA (amiR-TPXL3). The resulting mutants exhibited growth retardation, was linked...
Chilli veinal mottle virus (ChiVMV), a potyvirus, is widespread over the world. In China, it was first reported in chili pepper (Capsicum annuum) Hainan Province (south China) 2006 (2). Subsequently, tobacco (Nicotiana tabacum) Yunnan (southwest 2011 (1). Sichuan one of largest vegetable producing areas China. May 2012, tomatoes with leaves displaying virus-infected symptoms like mottling, mosaic, narrowing, or curling were observed several fields Chengdu, eastern Province, southwest Of 20...
Arabidopsis thaliana homeodomain-leucine zipper protein 1 (HAT1) belongs to the (HD-Zip) family class II that plays important roles in plant growth and development as a transcription factor. To elucidate further role of HD-Zip factors defense, A. hat1, hat1hat3 hat1hat2hat3 mutants HAT1 overexpression plants (HAT1OX) were challenged with Cucumber mosaic virus (CMV). HAT1OX displayed more susceptibility, while loss-of-function exhibited less susceptibility CMV infection. its close homologs...
