Phosphate (Pi) limitation is a constraint for plant growth and development in many natural and agricultural ecosystems. In this study, a gene encoding Zea mays L. protein phosphatase 2A regulatory subunit A, designated ZmPP2AA1, was induced in roots by low Pi availability. The function of the ZmPP2AA1 gene in maize was analyzed using overexpression and RNA interference. ZmPP2AA1 modulated root ...

Abstract Background This study aimed to assess the effects of different concentrations silicon (Si) nutrient sources, including bulk dioxide (bSiO 2 ) and two types silica nanoparticles, nSiO (I) (II) at 1, 5, 10, 25, 50, 100 ppm in germination process stevia. The priming experiment was conducted using a completely randomized design with three replicates ensure reliability results. Results All ...

Lawns achieve environmental, functional, and aesthetical roles in urban environments. The objectives of this research were to assess the effect different salinity levels on Trichoderma isolates study spp. perennial ryegrass under salinity. T. harzianum (ThLem2017-01) atroviride (TaDP2019-01) had a higher mycelium growth rate than (TaDP2019-02) when low. In contrast, isolate at high superior res...

In order to investigating the effect of different tobacco cultivars residue on germination and seeding growth of soybean an experiment was conducted at laboratory and glasshouse in college of Sari Agricultural Sciences and Natural Resources University during 2007 as a factorial based on completely randomized design with four replications. Extracts of root and shoot from two different types of t...

BACKGROUND AND AIMS The objective of this study was to test whether the mean values of several root morphological variables were related to the ability to develop root-borne shoots and/or shoot-borne roots in a wide range of vascular plants. METHODS A comparative study was carried out on the 123 most common plant species from eroded lands in north-east Spain. After careful excavations in the ...

Alfalfa (Medicago sativa L.) production is dramatically reduced in acidic, Al-rich soil. Transgenic plants of several species overexpressing organic acid synthesis and/or organic acid transporter genes have shown enhanced tolerance to Al. The objective of this research was to evaluate the effect of the citrate synthase (CS) and the Daucus carota L. plasma membrane H+-transporting adenosine trip...

● Background and aims. The objective of this study was to test whether the mean values of several root morphological variables were related to the ability to develop root-borne shoots and/or shoot-borne roots in a wide range of vascular plants. ● Methods. A comparative study was carried out on the 123 most common plant species from eroded lands in NE Spain. After careful excavations in the fiel...

Functional screening of an Arabidopsis cDNA library enabled the identification of a novel cDNA, ESR1 (for Enhancer of Shoot Regeneration), that can confer cytokinin-independent shoot formation when overexpressed in Arabidopsis root explants. Neither callus induction nor root formation was affected by ESR1 overexpression. ESR1 encodes a putative transcription factor with an AP2/EREBP domain. Sur...

Cadmium (Cd) is one of the highly toxic, non-essential heavy metals that inhibit plant growth and development by prompting chlorophyll loss affecting photosynthetic activities. This study investigated efficacy Spirulina platensis Sargassum polycystum extracts in alleviating Cd stress Pak Choi at morpho-biochemical, anatomical, molecular levels. Different concentrations (0, 25, 50, 100 mL/L) S. ...
