Strigolactones are a recently identified class of hormone that regulate multiple aspects of plant development. The DWARF14 (D14) α/β fold protein has been identified as a strigolactone receptor, which can act through the SCFMAX2 ubiquitin ligase, but the universality of this mechanism is not clear. Multiple proteins have been suggested as targets for strigolactone signalling, including both dir...

This paper presents a Z-source inverter which has been proposed as an alternative power conversion concept for adjustable speed AC drives. It is having both voltages buck and boost capabilities as they allow inverters to be operated in the shoot through state. It utilizes an exclusive Z-source network (LC component) to DC-link in between main inverter circuit and the DC source (rectifier). By c...

Abstract This paper presents a comparison between PV system using Z source inverters and Quazi Z source inverters. The Z-source inverter employs a unique LC network to couple the inverter power circuit to the diode front end and can be shoot through to boost the DC link voltage. By controlling the shoot-through duty cycle, the PV array output voltage is controlled and the maximum power point tr...

Successful sexual reproduction of a plant with prolific seed production requires appropriate timing of flowering and concomitant change of architecture (e.g. internode elongation and branching) to facilitate production of the optimal number of flowers while enabling continued resource production through photosynthesis. Florigen is the prime candidate for a signal linking the two processes. Grow...

Rapid clonal propagation through in vitro techniques using cotyledonary node as an explant has been attempted in the high yielding, tikka-susceptible (ICG 11337, AK 1224, ICGS 44, JL 24) and tikka-immune (ICG 6284) varieties of Arachis hypogaea L. Cotyledonary nodes were excised from the 12–15 days-old axenic seedlings and cultured in the presence of various concentrations of N6 –benzylaminopur...

Background and objectives: Haplophyllum canaliculatum is an endemic and endangered Iranian plant from Rutaceae family. The object of this work was to study the volatile production in established shoot and callus cultures of Haplophyllum canaliculatum as well as isolation, identification and sequencing of 18S rRNA gene from callus culture. Methods: Shoot and callus cultures of H. canaliculatum w...

abstract in order to study the effects of variety, water regime, zinc and cadmium levels on concentration, content and translocation of p, cu, fe and mn on rice, a factorial experiment was conducted consisting of four factors including: two varieties of rice (vandana and hashemi), two water regimes (flooded and nonflooded), three levels of zinc, and three of cadmium (0, 5 and 10 mg kg-1). the e...

conventional methods of pear breeding, largely based on intra- and inter-specific hybridization, are difficult because pear is highly heterozygous, polygenic and has a long juvenile period. genetic improvements of pear cultivars are possible through induction of mutations and gene transfer by genetic engineering. a general prerequisite for these approaches is to establish an efficient plant reg...

Punicagranatum cv. Malassaveh is one of the most desirable commercial cultivars in Iran. In thisstudy some experiments were conducted to introduce the best hormonal treatments for directadventitious shoot regeneration from mentioned cultivar via cotyledonary explants. For thispurpose, both liquid and agarMurashige and Skoog (1962) (MS) medium supplemented with BAat 2, 4.5, 9, 13 μM alone and in...
