Morpho-anatomical characterization and DNA barcoding of Artemesia vulgaris L
This study aims to identify A. vulgaris both in terms of descriptive morpho-anatomy and DNA barcoding using BLAST and phylogenetic tree reconstruction. The morpho-anatomical character was observed on root, stem, and leaf. DNA barcoding analysis was carried out through amplification and alignment of the rbcL and matK genes. All studies were conducted on three samples from Taman Husada (Medicinal Plant Garden) Graha Famili Surabaya, Indonesia. The anatomical slide was prepared by the paraffin method. Morphological studies revealed that the leaves of A. vulgaris both on the lower-middle part and on the upper part of the stem ...

Inheritance of breeding traits in Karakul sheep under different selection approaches
Braz J Biol. 2024 Feb 26;84:e278810. doi: 10.1590/1519-6984.278810. eCollection 2024.ABSTRACTIn the previous century, each intrabreed type of the Karakul sheep breed was characterized by significant numbers, representing a super population with rich genetic diversity. However, over time, the genetic diversity within the breed's gene pool has undergone significant depletion. At present, the Karakul breed is predominantly composed of only two small populations, distinguished by their fur colors: black and gray. Consequently, under such circumstances, genetic advancements in breeding endeavors are likely to be relatively limi...

Correlative variation of economically valuable traits in South Kazakh Merino
The objective of our research was to investigate the correlative variability of key economically valuable traits that characterize the overall functional state of sheep organisms under varying environmental conditions. The study was conducted at the "Sharbulak" breeding farms and the "Samat" peasant farms in the Kazygurt district of the Turkestan region. Our findings reveal that one-year-old rams surpass ewes in terms of live weight by 32-37% and in terms of unwashed wool shearing by 21-23%. Two-year-old rams outperform ewes in live weight by 2.15-2.17 times and in unwashed wool shearing by 2.38-2.44 times. The highest phe...

Exploring of pyrazinamidase recombinant activity from PZA-sensitive and resistant Mycobacterium tuberculosis expressed in Escherichia coli BL21 (DE3)
Braz J Biol. 2024 Feb 26;84:e278911. doi: 10.1590/1519-6984.278911. eCollection 2024.ABSTRACTThe mutations of pncA gene encoding pyrazinamidase/PZase in Mycobacterium tuberculosis are often associated with pyrazinamide/PZA resistance. The H and R1 isolates showed significant phenotypic differences to PZA. The H isolate was PZA sensitive, but R1 was PZA resistant up to 100 ug/ml. The paper reports the pncA profile for both isolates and the activity of their protein expressed in Escherichia coli BL21(DE3). The 0.6 kb of each pncA genes have been subcloned successfully into the 5.4 kb pET30a vector and formed the pET30a-pncA ...

The relationship between the size of the otolith (length and weight) and the size of the fish (standard length and total weight) was determined using the linear regression model (y = a + bx). For the morphological description, the otoliths of three specimens were selected by standard length class (10mm). The morphological characters analyzed were chosen according to t...

Diversity of Anastrepha spp. (Diptera: Tephritidae) in the Chaco Biome
In this study, we surveyed the existing Anastrepha species in the Brazilian Chaco Biome. We evaluated possible influences of climate and vegetation on the occurrence of Anastrepha spp. For this, we used traps and hydrolyzed protein as bait. Collections were carried out in three distinct floristic compositions in the Chaco biome, from permanently dry areas to flooded sites. We identified Anastrepha fraterculus (Wiedemann, 1830), A. sororcula Zucchi 1979, A. undosa Stone 1942, and A. daciformis Bezzi 1909. The dry and flooded environment did not influence the occurrence of Anastrepha species. The presence of multiple hosts i...

Ecophenotypic Variation of Midas Cichlid, Amphilophus citrinellus (Gunther, 1864), in Lake Batur, Bali, Indonesia
This study aimed to identify the interaction between habitat, water quality, and Midas cichlid in Lake Batur, facilitating morphometric variances in the fish populations. The fish were captured at five locations in Lake Batur using fishing rods, community nets with mesh sizes of 2-3 inches, experimental gillnets with mesh sizes of 1 inch, and fish scoops in floating net cages during August and November 2022. There were 46 fish samples caught from the five stations, all photographed using a digital camera and later measured using the ZEN 2012 software. The fish measurement employed a truss morphometric method using 21 disti...
