Acacia auriculiformis, one of the short rotation and fast growing tree species is known for its pharmacological properties notably anti-helminthic, antifilarial, microbicidal, spermicidal activity etc. Conservation of Acacia auriculiformis is essential via ex situ plantation as the seed germination rate of this plant species has been reported very poor around 20-28%. Clonal multiplication forms...

Plants are known for their capacity to regenerate the whole body through de novo formation of apical meristems from a mass of proliferating cells named callus. Exogenous cytokinin and auxin determine cell fate for the establishment of the stem cell niche, which is the vital step of shoot regeneration, but the underlying mechanisms remain unclear. Here, we show that type-B ARABIDOPSIS RESPONSE R...

The present study was carried out to investigate micropropagation possibility and determine the optimal medium composition and plant growth regulators (PGRs) combinations under in vitro conditions. The cotyledon and epicotyl explants obtained from 1 month old in vitro grown seedlings were used in MS medium containing BA (0.1, 0.2, 0.5, 1, 2 and 3 mg-1) and TDZ (0.1, 0.2, 0.5, 1, 2 and 3 mg-1) e...

To obtain a suitable explant and efficient culture medium for plant regeneration in spinach, two cultivars of Melody and Karaj local seedlings were chosen. A hypocotyl and cotyledon segments as well as shoot tip explants were dissected from seedlings. The explants were then cultured on MS medium supplemented with IAA, GA3, NAA, and BAP and their response to this media was studied. A completely ...

the first successful and an efficient regeneration system on in vitro direct plant regeneration of agastache foeniculum was reported. the experiment were done in factorial design with three replications and explants were cultured in ms media fortified with different concentrations of bap and tdz (0, 2.2, 4.4, 8.8 μm) in combination with 3 levels of iaa (0, 1.1 and 2.2 μm). anova analysis showed...

Objective: Here, we established the protocol for plant regeneration of Psoralea corylifolia via In-vitro micro propagation. Methods: The Apical meristems was used as the explants cultured on Murashige and Skoog (1962) medium (MS) supplemented different concentrations and combinations of plant growth regulators, 6-Benzylaminopurine (BAP), Kinetin (Kn), 1-Naphthaleneacetic acid (NAA) and B5 vitam...

We developed a new procedure for Agrobacterium-mediated transformation of plants in the genus Beta using shoot base as the material for Agrobacterium infection. The frequency of regeneration from shoot bases was analyzed in seven accessions of sugarbeet (Beta vulgaris) and two accessions of B. maritima to select materials suitable for obtaining transformed plants. The frequency of transformatio...
