Clear Differentiation

The aim of this paper was to analyze the segregation of some polymorphisms in three genes (CAPN1, CAST and DGAT1) related to meat quality in the Lidia cattle breed and some of its main lineages. To that effect, 119 individuals from the Lidia breed were analyzed. Although the association between the polymorphisms and the phenotype has never been demonstrated in this breed, the absence of fixed genotypes for these polymorphisms in the studied population makes the Lidia cattle a good candidate to develop selection objectives. The clear differentiation among lineages for most of the genes studied reinforces the high reproductive isolation presented in the Lidia cattle as revealed by previous studies on the structure of the population within the Lidia breed using microsatellite markers. Considering both issues in the design of breeding schemes will be necessary to save the lineages and not to lose this valuable genetic resource. Finally, it would be necessary to carry out an in depth search for new polymorphisms in genes associated with meat quality and to perform needed association analyses between the SNPs segregating in Lidia cattle and traits of economic interest.

Abstract. Saptadi D, Heliyanto B, Sudarsono. 2020. Short Communication: Cross-species amplification of microsatellite markers developed for Jatropha curcas within five species of Jatropha. Biodiversitas 21: 5072-5076. The transferability of SSR markers can be used to access the genetic diversity of related species. There are four close relatives of Jatropha curcas L in Indonesia, which can be utilized as a new diversity source through the interspecific crossing. This research was conducted to determine the ability of cross-species amplification of SSR markers developed from J. curcas to other Jatropha species (J. integerrima, J. multifida, J. gossypifolia, J. podagrica). It also investigated the relationship between these species. Out of 28 primers checked,11 primers showed cross-species amplification in all the species tested. Primer pairs EU099519, EU099528, and EU099525 have no transferability to other species. The overall percentage of polymorphism (PP) among all species tested was 95%, with the mean genetic similarity (GS) was 0.34. Least PP (17.35%) and highest GS (0.60) was found between pairs of J. podagrica and J. multifida. The correlation between the PP with GS was relatively high (0.75). The farthest and closest genetic distance was found between J. curcas/J. gossypifolia and J. podagrica/J. multifida, respectively. Further, selected primers from this study can be utilized in species differentiation, molecular identification of interspecific hybrids, and exploiting the genetic resource.

The Difference

Abstract The amount of intramuscular fat directly influences the meat quality. However, significant differences in the ability to accumulate intramuscular fat are present among different beef cattle breeds. While Wagyu, a cattle breed that originated from Japan, is renowned for abundant intramuscular fat, Brahman cattle generally have very little intramuscular fat accumulation and produce tougher meat. We identified that bovine intramuscular fat is derived from a group of bipotent progenitor cells named fibro/adipogenic progenitors (FAPs) which also give rise to fibroblasts. Thus, the variation in intramuscular fat development between Wagyu and Brahman is likely attributed to the difference in FAPs between these two breeds. In order to understand the gene expression difference between FAPs of the two breeds, single-cell RNA-seq was performed using total single-nucleated cells isolated from the longissimus muscle of young purebred Wagyu, purebred Brahman, and Wagyu-Brahman cross cattle. FAPs constitute the largest single-nucleated cell population in both Wagyu and Brahman skeletal muscle. Multiple subpopulations of FAPs with different gene expression profiles were identified, suggesting that FAP is a heterogeneous population. A unique FAP cluster expressing lower levels of fibrillar collagen and extracellular remodeling enzyme genes but higher levels of select proadipogenic genes was identified exclusively in Wagyu skeletal muscle, which likely contributes to the robust intramuscular adipogenic efficiency of Wagyu FAPs. In conclusion, the difference in the cellular composition and gene expression of FAPs between Wagyu and Brahman cattle likely contribute to their distinct meat quality.

Abstract Acer platanoides L. (Norway maple) is the most widespread native maple species in Europe, with a distribution from south and central Europe to northern Europe and Scandinavia. Acer platanoides is widespread throughout the territory of Latvia, and is mainly found in mixed broadleaf and conifer stands. The genetic diversity and differentiation of Latvian A. platanoides populations was analysed. Sampled populations were located throughout the territory of Latvia, and were selected to represent a range of ecological conditions, with differing levels of anthropogenic impact. A total of 496 individuals from 21 populations were analysed with eight microsatellite markers, which were developed from related Acer species. The obtained molecular data revealed a moderate level of polymorphism, and the analysed Latvian A. platanoides populations were moderately differentiated. This study provides an initial assessment of the genetic diversity and differentiation of Latvian A. platanoides populations, and is also one of the first reports of the analysis of A. platanoides populations using microsatellite markers. The results can be utilised to define A. platanoides genetic resource stands to ensure conservation of a wide range of germplasm.

ABSTRACTFor the Mpwapwa cattle breed in Tanzania, the efficiency of various breeding schemes including an open nucleus was investigated by model calculations. Artificial insemination and intensive recording of production are assumed to be applied in a nucleus which is the main breeding unit. As a pre-nucleus, associated herds with less intense data recording serve as the basis to screen superior cows for nucleus replacements, provide the capacity for progeny testing, and operate as bull multipliers for commercial herds.The criteria of efficiency were genetic gain and profit from selection for a dual purpose breeding objective (milk and beef) in a total population of 10 000 cows. Introducing a two breeding tier scheme through separating all recorded cows into a nucleus and pre-nucleus leads to an increase of the genetic gain rather than the profit. Further improvement is obtained by introduction of artificial insemination in pre-nucleus herds. The nucleus size should not exceed about 5% of the cow population and an optimum size of the pre-nucleus is about 15%. Opening the nucleus to replacement cows coming from the pre-nucleus affects the aggregate genetic gain very little although it can be recommended if milk yield is to be mainly improved or if the total profit is taken into account. Furthermore, the nucleus should be opened if there is little difference between the heritabilities in the nucleus and pre-nucleus and also in order to avoid detrimental effects of inbreeding and genotype × environment interaction.

He, J., Lu, L., Tian, Y., Tao, Z., Wang, D., Li, J., Li, G., Shen, J., Fu, Y. and Niu, D. 2011. Short Communication: Analysis of intramuscular fat and fatty acids of different duck breeds and their association with SNPs of duck A-FABP gene. Can. J. Anim. Sci. 91: 593–596. Intramuscular fat (IMF) is related to organoleptic characteristics of meat. Adipocyte fatty acid-binding protein (A-FABP) is one of the intracellular lipid-binding proteins involved in the transportation of fatty acids. The IMF contents of six duck breeds were measured, and the complete sequence and part of the 5' flanking region of duck A-FABP gene were obtained in this study. The IMF contents of different breeds were significantly different (P<0.05). Two SNPs were detected in the exon 3, one (HQ640428: g.2018A>G) was significantly associated with the contents of three fatty acids, total IMF and pectoral muscle weight. This work provides useful data for duck breeding.
