Yield of groundnut is constrained owing to diverse biotic and abiotic factors. Amongst biotic stresses two foremost foliar fungal diseases viz., late leaf spot and rust are universal and sparingly significant. Both conventional and modern breeding methods may be applied for improvement of groundnut. The current investigation was carried out to recognize genetic variability present among different groundnut germplasm with the use of morphological characters and SSR markers with the screening of resistant to leaf spot and rust resistant genotypes. In morphological examination, the analysis of variance divulged highly substantial differences among 48 germplasm lines. Initial screening of Germplasm was tried with the use of 125 SSR markers. But, based on banding pattern, 21 markers were found to be the best and selected for amplification of whole set of genotypes. Out of 21 markers, 16 were found to be highly polymorphic. Highest PIC value (0.8196) was detected for marker S021 representing 81% diversity. SSR Markers viz., PM42, PM204, PM377, S052, S076, S078 and S078 have PIC value more than 0.5, confirms their superiority in detection of polymorphism among studied germplasm lines. UPGMA analysis assemblage all the germplasm lines into three major clusters. Most of the foliar disease resistant genotypes were grouped together with higher genetic resemblance. Polymorphic markers identified in the study may be utilized further for molecular diversity analysis and the identified resistant genotypes may be employed further for the improvement of the crop.","PeriodicalId":14689,"journal":{"name":"Israel Journal of Plant Sciences","volume":" ","pages":""},"PeriodicalIF":1.0,"publicationDate":"2022-05-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42475324","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To overcome this problem, marker assisted introgression of semi-dwarfing (sd1) gene from semi-dwarf and high yielding rice varieties Rajendra Sweta and BPT5204 was attempted. Parental polymorphism was obtained through 109 SSR markers. The gene specific markers for fragrance and semi-dwarfing genes were used in the segregants to track their transfer. Recombinant selection was done for the donor genome segments flanking to the target gene i.e., sd1 followed by background selection through genome wide polymorphic SSR markers. More than 90% recurrent parent genome recovery was observed and the selected plants showed a reduction of plant height and flowering time in comparison to Katarni in the successive backcross generation along with the retention of aroma.

However, unsuitable environmental conditions tend to reduce the intensity of color change, greatly reducing the ornamental value of this species. Here, we investigated the discoloration of A. rubrum leaves from red to green during maturation. We first quantified leaf-color change in the L*, a*, b* color space, and found the most noticeable difference in the a* value, which changed from positive (more red) to negative (more green). In green leaves, photosynthetic pigment content was four-fold greater than that in red leaves, and anthocyanin content was significantly lowed (a 78.33% decrease). Consistent with this, levels of superoxide dismutase (SOD), peroxidase (POD), and catalase (CAT), as well as non-photochemical quenching, were significantly higher in red leaves. The activity levels of phenylalanine ammonia lyase (PAL), an initial enzyme in the anthocyanin synthesis pathway, were significantly positively correlated with anthocyanin accumulation. In contrast, polyphenol oxidase (PPO) enzyme activity was not correlated with any with other indicators. Transcriptome sequencing identified 2,161 differentially expressed genes (DEGs) between the red leaves and the green leaves (1,253 upregulated). Some of these DEGs (e.g., 4-coumarate: coenzyme A ligase (4CL), anthocyanidin synthase (ANS), phenylalanine ammonia lyase (PAL), flavonol synthase (FLS), chalcone synthase (CHS), dihydroflavonol 4-reductase (DFR), and flavanone 3-hydroxylase (F3H)) encoded important enzymes in the anthocyanin metabolic pathway, while others (e.g., MYB111 (EZV62_000212), MYB12 (EZV62_010323), and bHLH3 (EZV62_023045)) regulated anthocyanin accumulation. Our results have led to a clearer understanding of the physiological and genetic mechanisms underlying leaf-color change in A. rubrum, and provide a basis from which to improve the ornamental properties of colored-leaf tree species.","PeriodicalId":14689,"journal":{"name":"Israel Journal of Plant Sciences","volume":" ","pages":""},"PeriodicalIF":1.0,"publicationDate":"2022-03-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46058467","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Plantlets cultured in all media without BA presented a low budding rate. In contrast, plantlets cultured with BA showed 100% budding. With 13 μM BA, the leaves presented bigger stomata and wider opening. Plantlets cultured with BA had lower contents of photosynthetic pigments. MS treatments without BA supplementation did not show any change in the pigments’ ratios. Plantlets cultured with BA had lower activity of the water-splitting complex and signs of photoinhibition damage. This resulted in the reduced performance of the photosynthetic apparatus.

Seed development is a highly complicated process which involves the interaction between phytohormones which regulate the process at different stages of morphogenesis. The orthodox seed development is marked by three distinct stages such as histodifferentiation, reserve accumulation and drying but in recalcitrant seeds, drying phase is absent. Recalcitrant seeds show marked differences from orthodox seeds in development. The onset of different stages is marked by a definite peaking and lowering of phytohormones and the hormonal pattern varies in orthodox and recalcitrant seeds. The present study was conducted to understand the interplay of phytohormones during embryogeny and the following natural embryo desiccation in the recalcitrant seeds of Vateria indica L.

Endophytic bacteria residing in the nodules and roots of chickpea plants enable host in combating these stresses. Twenty one endophytic bacteria isolated from nodules and roots of chickpea were screened for multiple plant growth promoting traits like ammonia, organic acid, siderophore, hydrogen cyanide (HCN) and phytohormone indole acetic acid (IAA) production. Out of these, 86% isolates produced ammonia, around 50% isolates produced organic acid, HCN and siderophore, 29% isolates produced ACC (1-aminocyclopropane-1-carboxylic acid) deaminase, while only 14% isolates solubilized phosphate. Interestingly, all the isolates were able to produce IAA ranging from 11.6–85.2 μg/ml, isolate CPJN 13 being the maximum IAA producer (85.5±2.33 μg/ml). Isolate CPJN13 was selected for IAA optimization studies. The yield of IAA increased up to 4 fold i.e. 331±4.96 μg/ml at optimized conditions. IAA production was also confirmed by TLC and HPLC analysis of crude IAA extract. The application of CPJN13 on chickpea seedlings resulted in significant increase in plant growth parameters. The 16S rDNA sequencing of CPJN13 revealed its similarity with Pseudomonas lini strain and submitted to NCBI with accession number MF574502. To best of our knowledge, this is the first report of the presence of P. lini as endophyte in chickpea nodules. The results of this study imply that the endophytic P. lini has a potential role to enhance the plant growth.","PeriodicalId":14689,"journal":{"name":"Israel Journal of Plant Sciences","volume":" ","pages":""},"PeriodicalIF":1.0,"publicationDate":"2021-12-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42319117","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
