The results revealed that growing Faba bean in a phosphorus-deficient environment induced a reduction in the plant growth, net photosynthesis, SPAD index, and tissue phosphorus content. Genotypic variations were observed, with TUN demonstrating relative tolerance as compared to the other genotypes, by exhibiting a higher capacity for phosphorus uptake under deficiency conditions, lesser phosphorus deficiency stress index (PDSI), higher phosphorus tolerance index (PDTI), and better phosphorus use efficiency (PUE). The latter are two physiological traits that discriminate the studied genotypes. They can be used for further screening programs.

At present, one of the most effective ways to manage the diseases by selecting, breeding, and cultivating banana varieties with very high Fusarium wilt resistance. To this end, this study utilized transcriptome sequencing technology to analyze Fusarium wilt resistance in the root system, leaves, and corms of healthy and diseased Baodaojiao banana (Fusarium wilt resistance variety) plants. The DEGs identified in the roots, leaves, and corms included transcription factors such as bHLH, WRKY, NAC, ERF, the enzymes mannan synthase, alkaline/neutral invertase, galacturonosyltransferase and phosphoenolpyruvate carboxylase kinase, and other related enzyme genes. Additionally, among the differentially expressed enzyme genes involved in plant defense processes (peroxidase, glutathione S-transferase, β-glucosidase, laccase, cellulose synthase, and chitinase), peroxidase was the most abundant. Moreover, most of the differentially expressed genes (DEGs) were expressed at markedly higher levels in healthy plants than in diseased plants, and such peroxidase genes may be significantly associated with plant Fusarium wilt resistance. The results of this study provide the basis for the study of the molecular defense mechanisms of Baodaojiao banana plants against Fusarium wilt; provide reference data for the further exploration of the functions and complex network regulatory mechanisms of Fusarium wilt resistance genes.</p>","PeriodicalId":21477,"journal":{"name":"Russian Journal of Plant Physiology","volume":"40 1","pages":""},"PeriodicalIF":1.4,"publicationDate":"2024-07-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141571377","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}

Considering the complexity and labor intensity of collecting the roots of woody plants, especially coniferous plants, it is of particular importance to use a suitable method for the desorption of excess nutrients from the root surface to avoid the overestimation of nutrient content within the roots. In the present study, various methods for sample preparation of the roots of both Scots pine (<i>Pinus sylvestris</i> L.) seedlings grown in hydroculture with different aeration regimes and saplings grown in soil substrates were investigated to determine the contents of magnesium, potassium, calcium, phosphorus, iron, manganese, zinc and copper. The possibility of using root samples frozen in liquid nitrogen was also investigated. The effectiveness of different desorbing agents such as Na₂-EDTA, dithionite-citrate-bicarbonate, CaCl₂ and MES-Tris for nutrient removal from the root surface, as well as the duration of incubation, were studied. It was shown that desorption of nutrients from roots using EDTA is the preferred method when working with soil-grown roots. In the absence of iron-manganese plaques on the root surface, treatment of roots with DCB should not exceed 5-10 minutes to avoid ion leakage from root cells. If it is not possible to use any extraction methods, it is sufficient to mechanically remove the remaining soil particles from roots, rinse the roots with water and dry. However, this sample preparation method is not suitable for determining the iron content in roots.</p>","PeriodicalId":21477,"journal":{"name":"Russian Journal of Plant Physiology","volume":"6 1","pages":""},"PeriodicalIF":1.4,"publicationDate":"2024-07-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141571369","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}

However, climate change and frequent cyclonic storms with heavy rains during grain maturation periods have led to a significant reduction in rice yield and quality (20–30%) due to pre-harvest sprouting (PHS) damage. PHS has become a widespread issue globally, resulting in significant economic losses for Indian farmers, amounting to billions of rupees annually and severely impacting the country’s economy. Developing protocol and PHS-resistant rice genotypes is essential to mitigate the significant economic losses experienced by farmers and meet the growing demand for food grain with the increasing population. This study was aimed to developing the efficient protocol to identify PHS-resistant rice genotypes by evaluating 96 genotypes under laboratory and field conditions at 20, 25, 30, 35 and 40 days after flowering (DAF). To evaluate the PHS resistant genotypes we have developed the efficient and standard protocol for the present study. The results showed a positive correlation between phenotypic responses under laboratory and field conditions. Based on the germination percentage exhibited under laboratory and field conditions, the genotypes were grouped into four clusters using K-clustering and dendrogram clustering analysis. Out of 96 genotypes evaluated 19 grouped as highly susceptible (45 to 88%), 14 were moderately susceptible (10 to 45%), 51 were moderately resistant (0.10 to 10.00%), and 12 were highly resistant with zero percent germination at all flowering stages. The study also evaluated the genotypes for days to germination from 20 to 40 DAF. The highly susceptible genotypes germinated earlier (3 days) than moderately susceptible and resistant genotypes (4 to 6 days).

Chlorophyll fluorescence measurements and the calculated JIP test parameters showed that salt stress did not damage PSII reaction centers in both barley cultivars but reduced the rate of electron transport reactions from reaction centers to the plastoquinone pool in the genotype Erginel-90. Moreover, changes in ΔRo and ФRo confirmed that electron transport in the genotype Erginel-90 was also reduced further than plastoquinone. In the genotype Tokak 157/37, however, photosynthetic electron transport reactions were maintained under salt stress conditions. Contrary to the genotype Tokak 157/37, the impairment in the photosynthetic efficiency led to oxidative stress in the leaf tissues of the genotype Erginel-90 under salt stress. This fact was confirmed by the lower foliar antioxidant activity, accumulation of H₂O₂ and malondialdehyde, and thus photooxidative damages in the photosynthetic pigments.
