The chloroplast genomes (Cp) of most plants in its family have been sequenced and annotated, but there are fewer studies on the characteristics of the chloroplast genomes and codon usage bias of Astragalus. In this study, we sequenced and annotated the complete chloroplast genomes of three Astragalus species, that systematically compared the chloroplast genome and codon usage characteristics of three Astragalus. Methods: In this study, we used three Astragalus species as materials. Firstly, we sequenced and assembled their chloroplast genomes. Subsequently, we analyzed the codon usage bias of the chloroplast genomes of the three medicinal Astragalus species using software such as CodonW, CUSP and SPSS. Result: The results illustrated that the length of Astragalus chloroplast genome ranges from 122,815 bp (A. dahuricus) to 123,729 bp (A. melilotoides Pall.). There were 107-110genes, including 75-76 protein-coding genes (PCGs), four ribosomal RNA genes (rRNAs) and 28-30 transfer RNA genes (tRNAs). In addition, the results illustrated that codons in three Cp genomes from Astragalus had the same 11 Optimal codons and ending with A/U. The codon usage frequency of five model creatures were compared and the results revealed that the codon preferences of Astragalus and five model creatures were pretty significant, the natural selection was the main factor in codon preference.

Methods: To assess the stability for BNF and seed yield, twenty-five mungbean genotypes were measured at eight diverse agro-ecological conditions, represented as two different seasons during spring and summer in two consecutive years (2016 and 2017) at two locations - TCA, Dholi, Muzaffarpur and Pusa Farm, RPCAU, Pusa, Samastipur, Bihar. To evaluate the most stable and superior genotypes, three parameters, viz., , bi and S2di were calculated. Result: There is a substantial amount of variability across genotypes and environments, as shown by the pooled analysis of variance. The genotype, Pusa 11-31 had shown regression near to unity, comprised with non-significant standard deviation along with higher mean seed yield and biological nitrogen fixation indicates that this is the most stable genotypes for the above traits.\u0000","PeriodicalId":17998,"journal":{"name":"LEGUME RESEARCH - AN INTERNATIONAL JOURNAL","volume":"46 23","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-01-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139447406","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Methods: We achieved the successful induction of transgenic hairy roots from common bean petioles through the utilization of Agrobacterium rhizogenes strain K599. Our experimentation encompassed a diverse array of common bean varieties and leaves of varying ages. Subsequently, we refined and optimized the procedure for hairy root induction. Result: Our investigations have revealed that the most conducive conditions for hairy root transformation with K599 are attained using 5-day-old leaves from the cultivar ‘Honghuaqingjia’, exhibiting a remarkable induction efficiency of 59%.

Result: The results showed that foliar spraying exogenous ABA effectively inhibited the increase of MDA content and relatively significantly improved the photosynthetic parameters such as Gs and Tr and alleviated the loss of yield factors caused by chilling stress. Compared with spraying water, spraying exogenous ABA can significantly increase the yield per pot of LXD 4 by 6.72~17.77% and TJH by 6.41~37.04% under low temperature conditions. In summary, foliar spraying exogenous ABA ameliorated the effects of chilling stress on the physiological characteristics of adzuki bean leaves and improved yield as a result of improved antioxidant defense mechanisms which impeded lipid peroxidation.

Benth) belongs to the family Fabaceae and sub-family Mimosoideae. This tree have multiple uses; fruit, firewood, honey, fodder, soap oil, tannin, hedges and shade. Naturally this plant species can be multiplied by seeds. Apart from genetic variability, the seedling progenies may take long time to first bearing and sometimes irregular bearing also noticed due to its genetic makeup. In order to overcome these drawbacks, vegetative propagation is the only alternate way to get genetically uniform, early bearing and high yielding characters. The age of rootstocks and season of grafting influences the success of the grafts and performance of the grafted plants. With this background, studies on age of rootstocks and season on grafting success in Manila Tamarind was carried out. Methods: An experiment was conducted to assess the effect of season and age of the rootstocks in Manila Tamarind (Pithecellobium dulce). The experiment was laid out in factorial randomized block design with 15 treatment combinations and four replications. In this study, three rootstocks of different age viz., 6, 9 and 12 months old were grafted during June, July, August, September and October. Result: The main and interaction effects on age of rootstocks and season of grafting had a significant influence on survival percentage, number of days taken to first sprouting, number of leaves per plant and chlorophyll content of manila tamarind under controlled conditions. The softwood grafting performed on nine month old rootstocks during September recorded the highest survival percentage and it was significantly different from all other treatments.

(M. falcata L.) is widely distributed in Xinjiang and Inner Mongolia, which is a significant source of resistance genes. Its seeds have a high level of physical dormancy (PD). The current study aimed to study the dormancy characteristics, water absorption characteristics and methods for releasing hard seeds of M. falcata L., to reveal the the relationship between seed coat structure and water absorption and to understand the dormancy characteristics, which can provide theoretical basis for seed dormancy and seed biology research. Methods: Seed germination rate (GR), absorption, germination inhibitor activity and initial site of water entry into seeds were measured to investigate the causes of seed dormancy. Treatments to break dormancy included: (1) sandpaper sanding, (2) ultrasonic treatment for 30 min after sandpaper sanding, (3) 98% sulfuric acid immersion (5,10, 20, 40, 60 and 120 min) and (4) hot water immersion at different temperatures (50, 60, 70, 80 and 90oC) for 10 min, 20 min and 30 min. Result: The results showed that the hard rate of untreated seeds was 99.33% and the hard rate after the seed coat was scratched was 1.33%. Based on the inhibitory activity test of M. falcata L. seeds, high concentration seed extract has an inhibitory effect on the growth of other seeds. The toludine staining test showed that the hilum and microscope are the initial and main parts for seed water absorption. The germination rate of seeds after soaking in 98% sulfuric acid for 40 minutes and ultrasonic treatment with sandpaper for 30 minutes is higher than 94%, which is an effective method to relieve the PY of M. falcata L. seeds.","PeriodicalId":17998,"journal":{"name":"LEGUME RESEARCH - AN INTERNATIONAL JOURNAL","volume":"31 9","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-12-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138955667","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
