The improvement of oil quality and resistance to broomrape in sunflower genotypes resistant to herbicides

Sunflower crop has an important place in the word agriculture, due to many advantages, as the capacity to release high seed yield and good oil content. For improving different characteristics, by breeding methods, we need sources as genes donors. Genetic resources in sunflower, which could to be used as base of creating new inbred lines or as donor sources for genes controlling different characteristics, in the inbred lines breeding, are made up of old or new varieties, hybrids and inbred lines, induced mutations, synthetic populations, as well as sunflower wild species. Herbicide resistant crops are becoming increasingly common in agricultural production. A wild population of annual Helianthus annuus was the source for developing cultivated sunflower genotypes resistant to imidazolinone and sulfonylurea herbicides. There have been created inbred lines as sources for the genes transferring in the elite lines. The quality of sunflower oil can be modified by means of induced and spontaneous mutations. The sunflower lines, sources for high oleic acid content, there have been obtained from a Russian variety, created by chemical mutation. Using these sources we transferred genes for improving the oil quality, in our elite lines, resistant to herbicides. Broomrape, caused by Orobanche cumana Wallr. is a parasitic weed which infests sunflower roots, causing severe crop losses. Since broomrape is a highly variable parasite, the breakdown of resistance is a frequent phenomenon and multiple sources of resistance are needed. Genetic resistance to broomrape it was introduced in the sunflower crop from the wild relatives (H. tuberosus, H. maximiliani, H. debilis). The inbred lines created by interspecific hybridization have been used for the improvement of resistance to this parasite, of the lines resistant to imidazolinone and sulfonylurea herbicides

ORAL THRUSH IN PREGNANT WOMEN: CAUSES, RISKS AND PREVENTION STRATEGIES

Canker sores are a common condition among pregnant women, having a significant impact on oral and overall health. This article explores the causes, risks, and prevention strategies associated with mouth sores during pregnancy. Hormonal changes, weakening of the immune system, and stress are relevant factors in their occurrence. Risks include physical and emotional discomfort, as well as possible pregnancy complications. Proper oral hygiene, balanced nutrition, and stress reduction are essential strategies for preventing oral thrush. Treatment during pregnancy requires a gentle approach, and treatment options must be safe for the mother and baby. In conclusion, proper management of mouth sores during pregnancy is essential for the oral and general health of pregnant women and the fetus. The use of transdermal systems for administering crucial oils to pregnant women is an innovative and effective method of treatment of canker sores in pregnant women, offering multiple benefits and ensuring increased safety for mother and baby
