RESUMO
Animal-derived products have an important role in treating many health conditions and have widely been used across cultures. In South Asia, ethnozoological research has been conducted only by a small number of researchers. Therefore, this area of research needs further exploration in order to preserve the eroding ethnozoological knowledge of medicinal animals severely affected by ongoing social change. This study was conducted in the region of Jammu and Kashmir from February 2019 to August 2021. The study was carried out among eight different ethnic groups living in the region. A total of 374 informants were selected and data were collected through semi-structured interviews and verified through group discussions. Data was analyzed using different statistical tools, including R 4.0.0. The cross-cultural data were compared through Bioinformatics and Evolutionary Genomics software and later subjected to further analysis, applying Pearson correlation and ordination techniques (Principal Component Analysis). We recorded a total of 79 animal species being used by the eight studied ethnic groups in the region. Wild animal species were mainly used for therapeutic purposes. Chest infections, sexual problems, and paralysis were frequently treated diseases. Flesh was the most commonly part used. The cross-cultural comparison showed a remarkable heterogeneity in the use of the animals among the different groups, which could be an effect to the historical sociocultural stratifications, as well as different religious affiliation of certain groups preventing them to forage or hunt certain animals. Some groups however showed prominent overlap of uses of some recorded species. For instance, Lerwalerwa and Bubalus bubalis were commonly used by both Gujjar and Pahari, which could be referred to the fact that they have gone through significant socio-cultural contact, and they are exogamous to each other. The Pearson correlation coefficient supported the strength and direction of an association between ethnic groups and regions. The study makes an important contribution to the field of ethnozoology in the Himalayas by providing insights to understand the historical human and nature relationships and supplying a baseline for developing future conservation efforts in the region to protect the wild fauna.
RESUMO
Phosphorus (P) is an essential macroelement supporting maize productivity and low-P stress is a limiting factor of maize growth and yield. Improving maize plant tolerance to low P through molecular breeding is an effective alternative to increase crop productivity. In this study, a total of 111 diverse maize inbred lines were used to identify the favorable alleles and nucleotide diversity of candidate ZmNAC9, which plays an important role in response to low P and regulation in root architecture. A significant difference was found under low- and sufficient-P conditions for each of the 22 seedling traits, and a total of 41 polymorphic sites including 32 single nucleotide polymorphisms (SNPs) and 9 insertion and deletions (InDels) were detected in ZmNAC9 among 111 inbred lines. Among the 41 polymorphic studied sites, a total of 39 polymorphic sites were associated with 20 traits except for the dry weight of shoots and forks, of which six sites were highly significantly associated with a diverse number of low-P tolerant root trait index values by using a mixed linear model (MLM) at -log10 P = 3.61. In addition, 29 polymorphic sites under P-sufficient and 32 polymorphic sites under P-deficient conditions were significantly associated with a diverse number of seedling traits, of which five polymorphic sites (position S327, S513, S514, S520, and S827) were strongly significantly associated with multiple seedling traits under low-P and normal-P conditions. Among highly significant sites, most of the sites were associated with root traits under low-P, normal-P, and low-P trait index values. Linkage disequilibrium (LD) was strong at (r2 > 1.0) in 111 inbred lines. Furthermore, the effect of five significant sites was verified for haplotypes in 111 lines and the favorable allele S520 showed a positive effect on the dry weight of roots under the low-P condition. Furthermore, the expression pattern confirmed that ZmNAC9 was highly induced by low P in the roots of the P-tolerant 178 inbred line. Moreover, the subcellular localization of ZmNAC9 encoded by protein was located in the cytoplasm and nucleus. Haplotypes carrying more favorable alleles exhibited superior effects on phenotypic variation and could be helpful in developing molecular markers in maize molecular breeding programs. Taken together, the finding of this study might lead to further functions of ZmNAC9 and genes that might be involved in responses to low-P stress in maize.
