Oak somatic and gametic embryos maturation is affected by charcoal and specific aminoacids mixture

Developmentally and stress-induced small heat shock proteins in cork oak somatic embryos.

The timing and tissue localization of small heat shock proteins (sHSPs) during cork oak somatic embryo development was investigated under normal growing culture conditions and in response to stress. Western blot analyses using polyclonal antibodies raised against cork oak recombinant HSP17 showed a transient accumulation of class I sHSPs during somatic embryo maturation and germination. Moreove...

Is sperm motility maturation affected by static magnetic fields?

Kinematic parameters were evaluated in mouse epididymal extracts to monitor maturation of sperm movement in animals exposed to static magnetic fields using the Sperm-Class Analyzer computerized image analysis system. For this purpose, animals were exposed to a field of 0.7 T generated by a permanent magnet over 10 or 35 days for either 1 or 24 hr/day. The values of the motion endpoints were sim...

Modification of maturation condition improves oocyte maturation and in vitro development of somatic cell nuclear transfer pig embryos

This study examined effects on the developmental competence of pig oocytes after somatic cell nuclear transfer (SCNT) or parthenogenetic activation (PA) of : 1) co-culturing of oocytes with follicular shell pieces (FSP) during in vitro maturation (IVM); 2) different durations of maturation; and 3) defined maturation medium supplemented with polyvinyl alcohol (PVA; control), pig follicular fluid...

Root Regeneration in Pistachio Rootstock is Affected by Auxin and Polyamines

Pistacia vera cv Badami-e-riz and P.vera cv Ghazvini are the most important and popular rootstocks in Iran, which tolerate salinity and phytophthora fungi. This study was conducted to evaluate the effects of various concentrations of polyamines and IBA on root regeneration of transplanted bare- rooted ‘Badami-e-riz’ and ‘Ghazvini’ pistachio rootstocks. The mean comparison between IBA and polyam...
