Abstract

The FGB gene is a gene that plays a role in synthesizing b-fibrinogen proteins and is often used as a molecular marker because it is useful for studying bird phylogenetics. The purpose of this study was to describe the character sequences of the FGB gene in Maleo birds (Macrocephalon maleo S. Muller 1864). This study uses laboratory exploratory methods. Alignment is done using the MEGA6 program (Clustal W). Phylogeny trees are constructed based on the Neighbor-Joining algorithm and the Juke-Cantor evolution model of the MEGA6 program. The sample in this study was 0.3 ml of blood from Maleo birds and members of the Megapodiidae group species used as a comparison. The results of this study indicate the length of the FGB 576 bp sequence and was identified with a base composition of 32.2% A, 30.4% T, 17.0% C and 20.3% G. Nucleotide composition of the sequence of Adenine-rich FGB genes. Analysis of the FGB gene sequence phylogeny tree produced a tree topology that was quite good and had the power to split at the interspecies level and place the maleo bird in its own line compared to other Megapoda genera.

Abstract

Plant Growth Promoting Rhizobacteria (PGPR) made from the roots of bamboo, mung bean, and putri embarrassment has not yet been applied to mung bean plants, specifically to determine its effect on the number, diameter, and quality of mung bean root nodules. Therefore, this study aims to explain the effect of PGPR fertilizer from the roots of bamboo, mung bean, and putri embarrassment on the number, diameter, and quality of nodules on mung bean (Vigna radiata L.) root nodules. The study was carried out by experiment, using a completely randomized design (CRD), which consisted of 4 treatments, namely: P0 (control) = without PGPR fertilizer; P1 = bamboo root PGPR fertilizer; P2 = green bean root PGPR fertilizer; and P3 = PGPR root shame daughter fertilizer. Each treatment was repeated 6 times. The data obtained was analyzed using the Analysis of Variance (ANOVA) which was processed using the XLSTAT 2020 program. The results showed that the PGPR fertilizer treatment from bamboo roots, mung bean roots, and embarrassed daughter roots was significantly different from the control or without PGPR. Among the three types of PGPR tested, it turned out that the PGPR from the roots of putri embarrassment had the most significant effect on the number of nodules (60.67); nodule diameter (1.91 mm); and absorbance (1.88). From these results, it is recommended that PGPR from the root of the embarrassed daughter be able to significantly increase the quantity and quality of mung bean root nodules.
