Cereal aleurone responses to gibberellic acid (GA3) include activation of synthesis of hydrolytic enzymes and acidification of the external medium. We have studied the effect of the pH of the incubation medium on the response of wheat (Triticum aestivum) aleurone cells to GA3. De-embryonated half grains show the capacity for GA3-activated medium acidification when incubation is carried out at p...

An experimental trial was carried out during the season from March 2018 – June at Horticulture farm of Lovely Professional University, Phagwara (Punjab). utilising a randomised block design, consists three replications. The current study included eleven treatments, including control with different PGR dosages Maleic hydrazide (200, 250, and 300 ppm, MH), Naphthalene acetic acid (50, 100, 150ppm...

the effect of plant growth regulator short time treatments ( ga3 and tdz) on the increase of vase life and qualitative traits of alstroemeria cultivars ‘odessa’ and ‘sacramento’ were investigated. cut flowers were treated with 24h pulse treatments which included different concentrations of ga3 and tdz. cut flowers were later held in preservative solution (sucrose 2% +nanosid 2ppm) and then thei...

Artemisia is one of the plants that can be used as an alternative medicine for malaria. The plant contains secondary metabolites in form artemisinin compounds function antimalarials. One efforts done to increase growth annua. by using a regulator gibberellins (GA3). Using Randomized Block Factorial Designs (RBFD) with first factor being concentration 50 mg.L-1 (K1), mg.L-1(K2), 150 (K3), 200 (K...

The roles of gibberellic acid (GA3) and abscisic acid (ABA) in the regulation of vacuolar pH (pH,) in aleurone cells of barley were investigated using the pH-sensitive fluorescent dye 2',7'-bis(2-carboxyethyl)-5(6)-carboxyfluorescein (BCECF). BCECF accumulated in vacuoles of aleurone cells, but sequestration of the dye did not affect its sensitivity to pH. BCECFloaded aleurone cells retained th...

BACKGROUND Arbutus unedo is a valuable Mediterranean shrub as an ornamental plant as well as fruit tree. Fresh fruits of A. unedo are a good source of antioxidants, of vitamins C, E and carotenoids and also are characterized by the high content of mineral elements. MATERIALS AND METHODS The effects of gibberellic acid (GA3) and cold stratification (CS) on seed germination performance were inv...

Phonetic segments are coarticulated in speech. Accordingly, the articulatory and acoustic properties of the speech signal during the time frame traditionally identified with a given phoneme are highly context-sensitive. For example, due to carryover coarticulation, the front tongue-tip position for /1/ results in more fronted tongue-body contact for a /g/ preceded by /1/ than for a /g/ preceded...

Toxicity of heavy-metals in soil is a major constraint for the production carrots (Daucus carota L.). Different plant growth regulators are being used to overcome this problem. It has been found that induce stress tolerance plants. In study, role exogenously applied regulator, gibberellic acid (GA3) was examined grown two carrot cultivars under four different levels lead (0, 50, 100, and 150 mg...

Buds from the branches cut during dormancy (end of January) were used as the initial explants and set to develop under laboratory conditions at room temperature. Aseptic culture was established on Murashige and Skoog (MS) medium with BA 2.0, IBA 0.5 and GA3 0.1 mg 1-1. MS media with BA and IBA or NAA and GA3 were used for multiplication phase, whereas medium MS with mineral salts reduced to 1/2...

Although gut microbiome composition is well defined, the mechanisms underlying community assembly remain poorly understood. Bacteroidales possess three genetic architectures (GA1-3) of the type VI secretion system (T6SS), an effector delivery pathway that mediates interbacterial competition. Here we define the distribution and role of GA1-3 in the human gut using metagenomic analysis. We find t...
