Genetic diversity of wheat (Triticum aestivum L.) plants-regenerants produced by anther culture

The study of genetic diversity of wheat (Triticum aestivum L.) plants-regenerants produced by anther culture method from hybrids involved in the Latvian wheat breeding programme was performed. Flow cytometry was used to test ploidy of 3×103 cells of each green plantregenerant, and universal retrotransposon based iPBS (inter primer binding sites) method were used to establish genetic diversity of plants-regenerants. Progenies of 13 genetically distant hybrids were involved in the study. Most of plants-regenerants have leaves with mixoploid cells. Seeds were formed only by plants-regenerants that had cells with (2n = 6x) ploidy. Majority of fertile plantsregenerants have more than 40 % of hexaploid (6x) cells. The percentage of 6x cells in plants-regenerants and diversity in cell ploidy demonstrated association with mother plant (hybrid) genotype. Percent of spontaneous diplodization was also genotype-dependent. In this experiment colchicine treatment had no significant influence on outcome of fertile plants- regenerants. New dominant allele in a hybrid plant was found in comparison with both parents what indicated possible retrotransposon moving. Genetic diversity of the plants-regenerants obtained in anther culture is a combination of parent’s allele segregation and somaclonal variation

Prognostic factors of self-rated health deterioration during Covid-19 in the Baltic States

Abstract Background In order to implement the necessary measures to prevent the consequences of the Covid-19 pandemics, long-term assessment of health status is needed. The objective of the study - to determine the prognostic factors of self-rated health deterioration during the first wave of Covid-19 pandemics. Methods The study was based on a sample of individuals from wave 7, wave 8 and Covid-19 add-on of the Survey of Health, Ageing and Retirement in Europe (SHARE) in the period from 2017 till 2020. The sample size was 4429 respondents - Latvia: 649, Lithuania: 1083, Estonia: 2697. Descriptive statistics as well as univariate and multivariate binary logistic regression was performed, including health determinants, demographics and factors associated with Covid-19. Results Based on univariate binary logistic regression analysis, the main predictors for deterioration of self-rated health (unadjusted OR; 95%CI) were: age 80+ years (reference group 50-59 years) for Estonia (3.03; 2.93-3.14), diagnosed with major condition since Covid-19 for Latvia (15.45; 15.14-15.77) and Estonia (6.75; 6.57-6.94), fair or poor health since Covid-19 for Lithuania (4.92; 4.86-4.99), loneliness since Covid-19 for Lithuania (5.03; 4.94-5.12), limited in activities due to health condition for Latvia (4.53; 4.42-4.64), depression since Covid-19 for Lithuania (3.78-3.71-3.85), limited in activities due to age for Latvia (3.01; 2.95-3.08), nervousness since Covid-19 for Lithuania (2.08; 2.04-2.12). All predictors were statistically significant for all three Baltic countries. Conclusions The results in all three Baltic States indicated a similar trend that, taking into account the influence of other factors, the most important predictive factors were related to health and demographic indicators. Only one factor related to the first wave of Covid-19 (in Latvia - nervousness since Covid-19, in Lithuania and Estonia - less or no direct contact with children since Covid-19) predicts deterioration in health. Key messages The results indicate that deterioration in health cannot currently be considered to be caused by the first wave of Covid-19. Further research to assess long-term impact of Covid-19 to health is needed. </jats:sec
