The Production of Haploids: A Review of Its Current Status and Future Prospects.

The genus comprises 52 species and 19 subspecies, with the cultivated sunflower ( L.) representing one of the most important oilseed crops in the world, which is also of value for fodder and technical purposes. Currently, the leading direction in sunflower breeding is to produce highly effective heterosis F hybrids with increased resistance to biotic and abiotic stresses.

Effects of Different β-Lactam Antibiotics on Indirect Tomato ( L.) Shoot Organogenesis and Growth Inhibition In Vitro.

A β-lactams that act by inhibiting the bacterial cell wall biosynthesis are one of the most common classes of antibiotics applied to suppress the growth of latent bacterial infection associated with the plant tissue culture, as well as in the -mediated transformation techniques. Plant sensitivity to antibiotics usually is species-, genotype-, or even tissue-specific and mainly depends on concentrations, growth conditions, and culture system. In the presented article, we estimated a comparative effect of four β-lactam antibiotics (Claforan, timentin, amoxicillin, and Amoxiclav) at different concentrations in an agar-solidified Murashige and Skoog (MS) culture medium supplemented with 5 mg L 6-benzylaminopurine (6-BA) and 0.
