Phytohormone-like acting compounds previously have been suggested to be involved in the phytostimulatory action exerted by plant-beneficial rhizobacterium Bacillus amyloliquefaciens FZB42. Analyses high-performance liquid chromatography and gas chromatography-mass spectrometry performed with culture filtrates of FZB42 demonstrated presence indole-3-acetic acid (IAA), corroborating it as one pivotal plant-growth-promoting substances produced this bacterium. In 5 mM tryptophan, a fivefold...
Citrus is the main fruit tree crop in world and therefore has a tremendous economical, social cultural impact our society. In recent years, knowledge on plant reproductive biology increased considerably mostly because of work developed model plants. However, information generated these species cannot always be applied to citrus, predominantly citrus perennial that exhibits very peculiar unusual biology. Regulation growth development an intricate phenomenon depending upon many internal...
In citrus, the occurrence of a sink effect on photosynthesis (A) is controversial. Leaf carbohydrates and photosynthetic rates in field‐grown trees Satsuma mandarin ( Citrus unshiu [Mak.] Marc.) cv. Okitsu, were measured to elucidate whether or not demand for photoassimilates regulates A. The data indicated that source‐sink imbalances induced by different treatments altered both soluble (sucrose, glucose fructose) insoluble leaves, as well rates. general, girdling defruiting increased starch...
Summary Chloride (Cl − ) is an essential nutrient and one of the most abundant inorganic anions in plant tissues. We have cloned Arabidopsis thaliana cDNA encoding for a member cation–Cl cotransporter (CCC) family. Deduced CCC proteins are highly conserved, phylogenetic analyses revealed their relationships to sub‐family animal K + :Cl cotransporters. In Xenopus laevis oocytes, A. protein (At CCC) catalysed co‐ordinated symport , Na Cl this transport activity was inhibited by ‘loop’ diuretic...
GH3 genes are main components of the hormonal mechanism regulating growth and development and, hence, deeply involved in a broad range physiological processes. They implicated homeostasis through conjugation to amino acids free form essential plant regulators such as indoleacetic jasmonic acids. In this work, we showed that OsGH3.1 overexpression rice caused dwarfism significantly reduced both auxin content cell elongation. Functional classification transcriptomic profiling revealed most...
Whole-genome duplication, or polyploidy, is common in many plant species and often leads to better adaptation adverse environmental condition. However, little known about the physiological molecular determinants underlying adaptation. We examined drought tolerance diploid (2x) autotetraploid (4x) clones of Rangpur lime (Citrus limonia) rootstocks grafted with 2x Valencia Delta sweet orange sinensis) scions, named V/2xRL V/4xRL, respectively. Physiological experiments study root-shoot...
The presence of fruit has been widely reported to act as an inhibitor flowering in trees. This study is investigation into the effect load on 'Moncada' mandarin and expression putative orthologues genes involved pathways provide insight molecular mechanisms underlying alternate bearing citrus.
During ripening, citrus fruit-peel undergoes 'colour break', a process characterized by the conversion of chloroplast to chromoplast. The involves progressive loss chlorophylls and gain carotenoids, changing peel colour from green orange. In present work, in vivo vitro effects supplemented nutrients (sucrose nitrogen) phytohormones (gibberellins [GA] ethylene) on change fruit epicarp Satsuma mandarin (Citrus unshiu (Mak.) Marc., cv. Okitsu), were studied. rate break was correlated positively...
We generated source–sink imbalances by defoliation and sucrose supplementation stem injection, to investigate effects of carbohydrate availability on fruitlet growth abscission in cv. Okitsu Satsuma mandarins (Citrus unshiu (Mak.) Marc.). Partial promoted abscission, whereas increased citrus fruit set more than 10%. Moreover, when applied together, counteracted the effect partial set. When was supplied continuously from flowering until harvest, it concentrations soluble insoluble sugars...
Carrizo citrange (Citrus sinensis×Poncirus trifoliata) is a citrus hybrid widely used as rootstock, whose genetic manipulation to improve different growth characteristics of high agronomic interest. In this work, transgenic plants have been produced overexpressing sense and antisense CcGA20ox1 (a key enzyme GA biosynthesis) under control the 35S promoter modify plant architecture. As expected, taller (sense) shorter (antisense) phenotypes correlated with higher lower levels, respectively,...
The characterization of the metabolome is a critical aspect in basic research and plant breeding. In this work, putative application metabolomics for phenotyping closely related genotypes has been tested. Crude extracts were profiled by LC-MS GC-MS, mass data extraction was performed with XCMS software. Result validation achieved principal component analysis (PCA). ability profiling methodologies to discriminate assessed after hierarchical clustering (HCA). Cluster robustness multiscale...
Abstract Background Improvement of Citrus , the most economically important fruit crop in world, is extremely slow and inherently costly because long-term nature tree breeding an unusual combination reproductive characteristics. Aside from disease resistance, major commercial traits are improved quality, higher yield tolerance to environmental stresses, especially salinity. Results A normalized full length 9 standard cDNA libraries were generated, representing particular treatments tissues...
Abstract A Citrus sinensis spontaneous mutant, navel negra (nan), produces fruit with an abnormal brown-colored flavedo during ripening. Analysis of pigment composition in the wild-type and nan suggested that typical ripening-related chlorophyll (Chl) degradation, but not carotenoid biosynthesis, was impaired identifying as a type C stay-green mutant. exhibited normal expression Chl biosynthetic catabolic genes chlorophyllase activity no accumulation dephytylated compounds ripening,...
Summary In many perennial plants, seasonal flowering is primarily controlled by environmental conditions, but in certain polycarpic signals are locally gated the presence of developing fruits initiated previous season through an unknown mechanism. Polycarpy defined as ability plants to undergo several rounds reproduction during their lifetime, alternating vegetative and reproductive meristems same individual. To understand how regulate we focused on alternate bearing Citrus trees that had...
The effects of ozone exposure on lettuce leaves were investigated by means gas exchange, modulated chlorophyll a fluorescence and antioxidants systems. High concentration decreased the rate photosynthesis at light saturation level changes in stomatal conductance transpiration rate. However, an increase intercellular CO 2 indicated decrease carboxylation efficiency. These data agreed with reduction non‐cyclic electron flow lower capacity to reduce quinone pool. Ozone affected ascorbate pool...
