Bioinformatic Analysis of Perfect Microsatellites SSR Sequences on Chromosome 1A of Triticum aestivum L.
Bioinformatic Annotation of Triticum aestivum 1A chromosome from assembled whole genome is not yet complete and lacks participatory contributions to provide more details on its physical map and analyze SSRs (mono-,.. hexanucleotide) statistical distributions. We present, in our work, a script in python language to pre-process the assembled chromosomal sequences and the Krait program for the structural annotation of chromosome 1A to show the possible distributions of all the SSR types as well as the primers likely to be used for PCR sequence amplification. Our results show that the python script is a good tool for genomic data pre-processing. Moreover, the dimeric motifs AG, AT and AC are the most abundant in 1A chromosome and are followed by mononucleotide and trinucleotide SSRs C and AAG respectively. The occurrence of tetra repeats on 1A chromosome is 4219 sequences (72716 bp) corresponding to 8.43% of the total 1A chromosome. The relative abundance and density are respectively 7.15 loci/Mb and 123.16bp/Mb. The highest distribution was observed for the trinucleotide motifs (n = 14,903), characterized by Ra = 25.24 and Rd = 514.94 bp/Mb. Within this category (Trinucleotide), the motifs AAG and AGG were the most dominant with values of 2,987 and 2,431, respectively. The Triticum aestivum 1A chromosome shows all of the SSR types. We observed a polymorphic and unevenly SSRs distribution along the 1A chromosome.
Soybean (Glycine max. (L.) Merrill) Vegetative Growth and Yield Performance under Organic Manures Nutrient Management System in South-Eastern Rajasthan
A field experiment was conducted at Research Farm of Agricultural Research Station (Organic Block, field No. 14), Ummedganj, Kota during kharif season 2020 and 2021 on clay loam soil to study the “Soybean (Glycine max. (L.) Merrill) vegetative growth and yield performance under organic manures nutrient management system in South-Eastern Rajasthan” which was laid out in randomized block design with three replications. The experiment comprised of tenth treatments viz. T1 (Control), T2 (100 % OM + 10% CU), T3 (100 % OM + 5% Panchgavya), T4 (75 % OM + 25 % VC + 10% VW), T5 (50 % OM + 50 % VC + 10% VW), T6 (75 % OM + JA 500 L/ha), T7 (75 % OM + GJA 500 kg/ha), T8 (100 % OM + LCB 1250 ml/ha), T9 (75 % OM + LCB 1250 ml/ha), T10 (75 % OM + LCB 1250 ml/ha + 10% SG). In this experiment application of different organic sources were applied to the soybean variety “JS 20-34”. A critical examination of data revealed that significantly higher plant height 45, 60 DAS and at harvest (41.0, 52.6 and 56.1 cm), number of branches/plant 45, 60 DAS and at harvest (5.0, 5.4 and 6.2), total number of nodules/plant at 45 and 55 DAS (46.3 and 44.0), effective nodules/plant at 45 and 55 DAS (41.2 and 34.5), chlorophyll content at 45 and 60 DAS (3.39 and 3.87 mg/g), plant dry weight 45, 60 DAS and at physiological maturity (108.7, 193.0 and 369.7 g/mrl) and crop growth rate 30-45, 45-60 DAS and 60-at physiological maturity (13.90, 16.87 and 17.67 g/m2/day) were observed in application of 50 % OM + 50 % VC + 10% VW over control. Application of 50% OM + 50 %VC + 10% VW was recorded significantly higher number of pods/plant (46.0) number of seeds/pod (2.77), pod length (4.79 cm) and seed index (11.05), seed yield (2160 kg/ha), straw yield (3124 kg/ha) and biological yield (5284 kg/ha) as compared to over rest of treatments. It can be inferred from the economic assessment of data that all the different organic manures treatments recorded significantly higher gross return ( 128172), net return ( 93584), B: C ratio (2.71) and production efficiency (24.55 kg/ha/day) were recorded in application of 50% OM + 50% VC + 10% VW as compared to over rest of treatments.
Ononis angustissima as a Traditional Remedy in four Provinces of South-West Algeria (Ethnobotanical survey)
The South-West of Algeria exhibits rich floristic diversity, with many medicinal plants deeply rooted into the healthcare practices of the local population. While ethnobotanical knowledge is important, there are still gaps in the data regarding the use of certain species, such as Ononis angustissima. This study presents the first ethnobotanical survey focused on Ononis angustissima conducted in the provinces of Saida, Namaa, El Bayadh, and Bechar. The primary objective was to document and preserve indigenous knowledge regarding the folk usage of this plant. In this study, semi-structured questionnaires were administered to 172 inhabitants and the collected data were analyzed statistically. Quantitative analysis revealed that the majority of respondents were a married herbalist man (87.2%), mostly older and with limited education including middle school (49.07%). The high frequently treated condition was metabolic disorders, particularly hypercholesterolemia (31.1%), using the dried (62.13%) aerial parts (57.73%), typically prepared as a decoction (75.6%) and administered orally (93.26%). These findings serve as a valuable resource for scientific research and could enrich both national and global pharmacopoeias.
Effects of genotypic diversity on population density of natural enemies of soybean
To test the effects of genotypic diversity on natural enemy population of soybean insect-pests an experiment was laid in kharif 2018 and 2019 at the Entomology Research Farm of ICAR-Indian Institute of Soybean Research, Indore. Totally 20 treatments were chosen for this experiment and out of the twenty treatments four treatments namely, T1, T6, T11 and T16 were four varietal mixture treatments. The results of the effects of genotypic diversity on natural enemy population of soybean insect-pests were revealed that highest population of coccinellids (2.32 coccinellids/m2) and spiders (11.74 spider/ m2) were found in treatment T16 (mixture of NRC-37, JS-9752, RSC-1046 and RKS-113) while rove beetle (2.54 rove beetle / m2) was found in treatment T1 (Mixture of JS-9560, JS-20-34, MAUS-47 and MACS-1460). Canthconidia (6.67 Canthconidia/m2) and Hover fly (11.74 hover fly/m2) were found highest in treatment T6 (JS-9305, JS-2029, RVS-2001-4 and Dsb-28-3) while predatory thrips (2.44 predatory thrips) was found in T11 (mixture of NRC-86, JS-335, JS-2098 and RKS-45). For insect pathogens the highest infected larva of defoliators viz., semoloopers and Spodoptera litura etc. by entomopathogenic fungi, Beaveria basiana (4.61 infected larva/m2) entomopathogenic fungi was found in T11 while Nomuriya rileyi (10.67 infected larva/m2) infected defoliators larva was found in T16. In case of parasitoids i.e., Encarsia transvenna (22.87 parasitized pupae/leave) (whitefly parasitoids) and braconids (3.69 parasitized pupae/leave) (lepidopterous parasitoid) were found highest in T16 (mixture of NRC-37, JS-9752, RSC-1046 and RKS-113). So, it is evident from above results that genotypic diverse treatments (varietal mixtures) have more number of all kinds of natural enemies than their respective sole varietal treatments.
Effect of Gibberellic Acid and Maleic Hydrazide on morphological and reproductive characters of okra [Abelmoschus esculentus (L.) Moench]
Field experiment was conducted to investigate the "Effect of Gibberellic Acid and Maleic Hydrazide on Growth of Okra [Abelmoschus esculentus (L.) Moench]" at V.P.O. Maheru, Tehsil Phagwara, District Kapurthala, Punjab under the Department of Horticulture, Lovely Professional University, Phagwara, Jalandhar, Punjab during the year 2018-19. The experiment utilized plant growth regulators and growth retardant, specifically gibberellic acid and maleic hydrazide, at varying concentrations in a Randomized Block Design layout. The results demonstrated that significantly higher growth parameters, such as plant height (98.00 cm) and leaf area index (2.016), were achieved with the application of Maleic Hydrazide 60 ppm combined with GA3 60 ppm. Additionally, the number of leaves per plant (33.18) and branches per plant (4.46) at 75 days after sowing (DAS) were recorded with the application of Maleic Hydrazide 100 ppm combined with GA3 60 ppm. Earliest flowering (36 days) was observed with the application of Maleic Hydrazide 100 ppm combined with GA3 60 ppm. Gibberellic acid promotes plant growth by enhancing cell elongation, while maleic hydrazide acts as a growth retardant, reducing excessive vertical growth while promoting branching. Combination of these chemicals at different concentrations showed improvements in various growth parameters such as plant height, leaf area, and early flowering. This indicates that the balanced use of growth regulators can optimize plant development and yield in okra cultivation.
