“…Cytogenetic approaches such as the root mitotic cell cycle and nucleolar activity evaluation have been proven to be fast and reliable methods to assign the most suitable treatments for seed priming, as demonstrated before in bread wheat [11,16]. These cytogenetic approaches have also helped evaluate the abiotic stress responses in the roots and leaves of other plant species [18,19,21,25,26].…”

“…The nucleolar size has been positively correlated with cell proliferation, rRNA transcription and transport or protein synthesis [31][32][33][34]. However, the nucleolar number and area changes in response to particular abiotic stress do not always follow the same trend among plant species [11,18,19,21,25,35]. Reducing the nucleolar number and/or area does not imply diminished nucleolar activity or protein synthesis [11,35,36].…”

“…Previously, we analysed how various concentrations of Fe and/or Zn used in bread wheat seed priming impacted root cell division and nucleolar activity [5,17,18]. Roots are growing organs in direct contact with soil or another substrate, and when exposed to excess micronutrients, their cell division is impaired and their growth is compromised due to the generated cytotoxicity [17,19,20]. The nucleolus is an organelle that senses the intracellular stress caused by drought, salinity or excess micronutrients, responding with changes in number, morphology, area and structure [5,[19][20][21][22].…”

The nucleolus is an organelle that senses the intracellular stress caused by drought, salinity or excess micronutrients, responding with changes in number, morphology, area and structure [5,[19][20][21][22]. Besides, the nucleolar activity directly implies that protein synthesis is highly required for vital biological processes and determines food quality [5,7].…”

Hexaploid triticale results from crosses between durum wheat and rye. Despite its high agronomic potential, triticale is mainly used for livestock feed. Triticale surpasses their parental species in adaptability and tolerance to abiotic and biotic stresses, being able to grow in acidic soils where a high amount of iron (Fe) and zinc (Zn) is typical. On the other hand, high amounts of these essential trace elements can be cytotoxic to bread wheat. The cytotoxicity induced by seed priming with a high concentration of Fe and Zn impaired root cell division and induced nucleolar changes in bread wheat. Such cytogenetic approaches were expedited and successfully determined cytotoxic and suited micronutrient dosages for wheat nutripriming. With this study, we intended to analyse the hexaploid triticale cv ‘Douro’ root mitotic cell cycle and nucleolar activity after seed priming performed with aqueous solutions of iron (Fe) and/or zinc (Zn), containing a concentration that was previously considered cytotoxic, to bread wheat and to infer the higher tolerance of triticale to these treatments. The overall cytogenetic data allowed us to conclude that the Fe + Zn treatment enhanced the root mitotic index (MI), mitosis regularity and nucleolar activity of ‘Douro’ relative to the control and the individual treatments performed with Fe or Zn alone. The Fe + Zn treatment might suit triticale biofortification through seed priming.

“…Work is underway to study the dynamics of the growth of thin roots in grapes [8]. The influence of mineral nutrients, carbohydrates, trace elements, strigolactones and brassinosteroids on the development of vines and fruit crops is studied [9][10][11][12][13][14]. However, there is practically no data in scientific literature on the effectiveness of natural growth regulators use and there is only general information about technological parameters of their application, including yeast.…”

The paper presents the growing experiment results on activating the regenerative ability of Moldova table variety grape cuttings by processing pressed baking yeast suspension. The present circumstance became the basis for conducting special studies to check cutting response to the treatment with baking yeast suspension, with the identification of drug optimal concentration. In spring, the two-eyed cuttings were completely soaked for 24 hours in water, and then they were placed with the basal ends in yeast suspension at various concentrations for the same time. Moreover, these yeast suspension concentrations were tested both in pure form and in combination with 3% sucrose. As a result of the conducted studies, it was revealed that pressed baking yeast suspension at certain concentration can have an activating effect on regenerative ability of grape cuttings. The use of yeast suspension together with sucrose solution increases their physiological activity. It was found that cuttings basal end soaking in yeast suspension at concentrations of 10-20 g/l, together with sucrose, contributed to rooting increased by 20-30%, the proportion of cuttings with three roots or more – by 22.5-30.0%, the number of roots by 13.5–16.2%. The best option was with a yeast suspension concentration of 20 g/l.

The antimicrobial properties of copper ions can reduce the overgrowth of microorganisms to a certain extent. That reduces the amount of antibiotics used, to avoid superbugs and potential harm. The authors reviewed the antimicrobial mechanisms of copper and copper‐containing nanoparticles (NPs), focusing on the factors influencing their antimicrobial properties. They concluded that the antimicrobial properties were better in environments conducive to the precipitation of copper ions and exposure to microorganisms. Comparing copper with other metal ions leads to the question of why copper is such an important antimicrobial metal ion. In recent years, with the development of science and technology and the understanding of the microscopic world, scientists have skillfully applied the antimicrobial properties of copper in various settings, from direct contact with food to breeding and hygienic environments, and have confirmed the safety of the application. However, because of the toxic effect of NPs, the future goal is to synthesize a copper‐containing NP with good biocompatibility and antibacterial efficiency to benefit human society.
