Assessment of the carcass traits of lambs with ¾ of the Texel breed genotype

Thirty six ¾ Texel (T) and 32 Ideal lambs were grown in feedlot for two months postweaning to evaluate final liveweight (FLW), relative average daily gain (ADGr) and various carcass characteristics, including: cold carcass weight (CCW), total lean weight (TLW), loin weight (LW), and total fat weight (TFW). Differences were found between males of the two genotypes in FW (P<.01) and TLW (P<.05); and between the females in TFW (P<.05). There were no differences between genotypes in ADGr. A multiple regression analysis relating FLW, as dependent variable, and the carcass variables as independent, showed that 73% of the variation in liveweight of the¾T animals was associated withLW and TLW. At conclusion of the confinement feeding, blood plasma samples from three lambs of each genotype/sex were analyzed for relative proportions of the mayor fatty acids and concentrations of total cholesterol and triglycerides. A negative relationship was found between the proportion of oleic acid and degree of fatness, expressed as (TFW/CCW) (100), whereas for linoleic acid the relationship was positive

Stress response and detoxification mechanisms involved in non‐target‐site herbicide resistance in sunflower

The nature of non-target-site herbicide resistance (NTSR) to imidazolinone (IMI) in HA425 sunflower (Helianthus annuus L.) has not yet been fully characterized but could be related to xenobiotic metabolism. The objective of this study was to evaluate the role of cytochrome P450 monooxygenases (P450s) and other detoxification-related proteins in NTSR in sunflower. Two sunflower inbred lines were used: HA 425, which is IMI resistant (Imisun), and HA 89, which is IMI susceptible. The growth response to the IMI herbicide imazethapyr in combination with the P450 inhibitors 1-aminobenzotriazole (ABT) or piperonyl butoxide (PBO) was evaluated in 15-d-old sunflower plantlets. Roots were collected, and label-free quantitation (LFQ) proteomic analysis was carried out to characterize the NTSR mechanisms involved in the IMI resistance trait in sunflower. The increased phytotoxicity of imazethapyr observed in the resistant line when ABT or PBO were present agrees with the hypothesis that NTSR mechanisms may contribute to herbicide resistance in sunflower. The herbicide treatment also led to changes in the levels of biotic and abiotic stress-related proteins, glutathione S-transferases, and cytochrome P450s, among others. Plant growth and root protein expression response to IMI herbicides in sunflower would be a combination of stress-related and detoxification mechanisms. Understanding the basis of NTSR becomes helpful to exploit this trait in sunflower crop and to develop xenobiotic-resistant, soil-remediating cultivars.EEA FamailláFil: Vega, Tatiana.
