The aim of this study was to investigate the effects of ethanolic extract of Pueraria tuberosa (PT) on sexual behaviour and androgenic activity. Male albino rats were divided into four groups of six animals each: control group 1 (2% acacia solution), PT-treated group 2 (50 mg/Kg), PT-treated group 3 (100 mg/Kg), and PT-treated group 4 (150 mg/Kg). Sexual behavior of male rats in the presence of...

The change in the developmental pathway of microspores from gametophytic to sporophytic is induced by stress during pretreatment of spikes and anthers. In our experiments, anther culture of three barley cultivars was tested with regard to the effect of chilling at 4 degrees C for 28 days, starvation in 0.3 M mannitol solution for 4 days, and a combination of both methods. Chilling was shown to ...

Atrazine is currently one of the most widely used herbicides in the United States and elsewhere. Here we examined 24 h in vitro and in vivo effects of atrazine on androgen production and on expression and activity of steroidogenic enzymes and regulatory proteins involved in cyclic adenosine monophosphate (cAMP)-signaling pathway in peripubertal rat Leydig cells. When in vitro added, 1-50 μM atr...

Wheat crop has a major role in current food system and global security. Beyond doubt, wheat production increased substantially, however, there been increase world’s population also, thereby, leading to supply demand. To fulfil this demand, science today needs more efficient new technologies for breeding with faster pace. Conventional is time consuming as it requires the selfing from F1 generati...

We report the first detailed genetic linkage map of rainbow trout (Oncorhynchus mykiss). The segregation analysis was performed using 76 doubled haploid rainbow trout produced by androgenesis from a hybrid between the "OSU" and "Arlee" androgenetically derived homozygous lines. Four hundred and seventy-six markers segregated into 31 major linkage groups and 11 small groups (< 5 markers/group). ...

Through anther and microspore culture methods, complete homozygous plants can be produced within a year as compared to the long inbreeding method. Isolated microspore culture is one of the most important techniques for rapid development of haploid plants. The efficiency of this method is influenced by several factors such as cultural conditions, growth regulators, plant media, pretreatments, ph...

Abstract The Balkan pepper breeding program aims to use in vitro embryogenesis (anther culture) develop doubled haploid lines with valuable traits. We analyzed the effectiveness of microspore on 17 genotypes comprised varieties, lines, and F 1 hybrids different varietal types (conical, bell shape, kapia) characterized agronomic traits newly generated lines. highest androgenic potential was obse...
