Diversity, pathogenicity, and biocontrol efficacy of Pseudomonas syringae strains isolated from a wide range of habitats in Jordan were investigated. Thirty-five infected plant samples (vegetable leaves and woody plant twig) were randomly collected. King's B agar medium was implemented and 124 colonies of P. syringae candidates were selected. Pheno...

Macrophomina phaseolina is the causative agent of a wide group of plant diseases exhibiting various symptoms via secreting an array of degrading enzymes including pectinases, and cellulases that mainly affect plant cell walls. This research was conducted during 2018 to 2019 to investigate the fungal biochemical and genetic variations of 25 M. Phase...

Micronutrient enhancement via biofortification is the only tool to reduce malnutrition of rice. The nutritional value of rice, especially iron, zinc, and selenium are usually low in many consuming communities. The aromatic rice cultivars have consistently higher concentration of iron and zinc in grain than the non-aromatic types. Zinc has multiple...

The present investigation was aimed at enhancing the quality and productivity of barley by the fertilizer and chito-san application. The field experiments were conducted in the northern region of Jordan, under the rain fed conditions in the main growing seasons of 2014/2015 and 2015/2016. The experiment was conducted in a well-designed split-plot h...

Actinomycetes is being involved in plant defense response and, plant-microbe interactions, flavonoid production by plants may be increased when the plant recognizes certain molecules or structures that characterize pathogen. Actinomycetes produce a wide variety of antibiotics and of extracellular enzymes. The objective of the present study was to d...

Aldehyde oxidase (AO) was proposed to convert indole-3-acetaldehyde (IAAld) to indole-3-acetic acid (IAA) primarily through the identification of endogenous IAAld and the efficient conversion of IAAld to IAA via AO. Involvement of AO in the production of IAA has been investigated in developing rice grains (OsAO). Analysis of phylogenetic tree, RT-P...

The major goal of this study was to evaluate the anti-hyperglycemic effect and the activity of hepatic enzymes after treating the streptozotocin-induced diabetic rats with the essential oil of Varthemia iphionoides . 24 wistar albino rats weighing between 180-200g were randomly grouped into four categories of six rats. Group A, normal control was r...

Forty wild individuals of wild Peganum harmala (P. harmala) were collected from four sites in Ma’an Governorate and were assessed for genetic variability by the method of random amplified polymorphic DNA (RAPD) PCR. Four primers produced 43 amplified bands and 23 of them were polymorphic. Miniature degree of genetic diversity was detected among stu...

Plant growth and productivity are adversely affected by drought. The sound of shortage of water on growth, yield and yield quality has been well deliberated in plants. In most cases growth, yield and yield quality are diminished under drought environments. There are four major strategic categories that represent the plant adaptation to desert, whic...

Antagonistic Bacillus sp. strain HMB8 and its concomitant Micrococcus sp. strain HMB7 were isolated from a healthy oral cavity of a volunteer. Phenotypic characteristics and 16S rRNA gene sequencing similarity confirmed that strain HMB8 belongs to Bacillus genus, whereas strain HMB7 belongs to Micrococcus genus. Isolated Bacillus sp. HMB8 exhibited...

Twenty four fungal species were screened for their ability to produce alkaline L-methioninase on methionine-glucose liquid medium. Aspergillus ustus AUMC 10151 displayed the highest yield of enzyme (10.8 U/mg protein), followed by A. ochraceus and Fusarium proliferatum. Upon optimization of the submerged fermentation (SmF)conditions, the maximum en...

Indole-3-acetamide (IAM) pathway was proposed to produce indole-3-acetic acid (IAA). This pathway was proven to be functional in many species of bacteria and expected to operate in plants based on the identification of IAM and IAM-hydrolase (AMI) activity in certain plant species. Available putative AMI sequences from a wide array of monocot and di...

doi:10.3390/plants3010095 plants ISSN 2223-7747 www.mdpi.com/journal/plants Article Abstract: Indole-3-acetic acid (IAA) synthesis is required for grain-fill in maize and appears to be regulated by cell-wall invertase (CWIN) activity. OsYUC12 is one of three IAA biosynthesis genes we previously reported as expressed during early rice grain developm...

Plant proteome databases were mined for a flavin monooxygenase (YUCCA), tryptophan decarboxylase (TDC), nitrilase (NIT), and aldehyde oxidase (AO) enzymes that could be involved in the tryptophan-dependent pathway of auxin biosynthesis. Phylogenetic trees for enzyme sequences obtained were constructed. The YUCCA and TDC trees showed that these enzy...

The indole-3-acetic acid (IAA) content of developing grains of Oryza sativa subsp. japonica was measured by combined liquid chromatography, tandem mass spectrometry in multiple-reaction-monitoring mode. The increase from 50 ng g(-1) fresh weight to 2.9 µg g(-1) fresh weight from 1 to 14 days after pollination was much larger than that previously re...

The rates of nitrogen fixation by symbiotic rhizobia are often two to three times higher than the ones exhibited by free-living nitrogen-fixing bacteria in soil. In this study, Rhizobium leguminosarum, Rhizobium meliloti, Rhizobium loti and Rhizobium ciceri were isolated and identified from leguminous plants grown at the north of Jordan. The aim of...

Question
I am doing a research using transcriptome co-expression analysis of enzymes involved in indole synthesis. who is interested in that topic so that can help doing some planned experiments in Arabidopsis?
Question
When I used ATTED-II to find genes co-expressd with indole synthase in Arabidopsis at different times, lists were completely different. Why?

Rock varnish is the skinny outer layer of rock surfaces in arid and semiarid regions, it is composed of clay minerals cemented together by oxides and hydroxides of manganese and iron. Al-Jafer basin is located in the south Jordan in a region that classified as a arid and semi-arid region with mean annual rainfall of about 50 mm . The basin has a total area of 13500 km2, scattered with a plenty of rock varnishes. It is well known that microbial communities associated with desert environments play pivotal roles in various biogeochemical cycles. This project aims to conduct, for the first in Jordan, a phylogenetic and functional analysis of the microbial communities associated with rock varnish in the arid region of Al-Jafer basin, using Next-generation DNA sequencing methods for the 16S rRNA gene analyses
