Dissemination, communication and exploitation in the CREDIT Vibes project
No full textThe CREDIT Vibes project aims to effectively communicate, disseminate, and exploit project
results, implement strategic communication plans and support the exchange of knowledge,
technology, and skills between partners and stakeholders. A comprehensive Communication,
dissemination, and exploitation plan was developed to guide outreach and visibility efforts.
This plan includes the creation of a unified visual identity, featuring the project logo,
templates for various document types, and standardized text for press releases.
Communication, dissemination, and exploitation plan will outline clear objectives, define the
target audiences, craft key messages, and specify dissemination tools and indicators for
evaluating the impact of these efforts. The strategy will ensure that various stakeholder groups
are informed according to their specific interests and needs. Dissemination occurs
continuously and extends beyond the project‘s duration through scientific publications and
conference presentations. Communication activities include engagement via the Nutribreeding
Hub, demonstration events, and social media (Twitter, LinkedIn, Facebook). All project
partners actively contribute to dissemination and communication efforts at national,
European, and international level by participating in scientific conferences, stakeholder
events, and other targeted forums to maximize outreach and engagement. Knowledge
management activities include the organization of conferences, workshops, and educational
events. Notably, the International Maize Research Conference, organized by the Maize
Research Institute, will feature a dedicated session on nutribreeding, showcasing project
outcomes and expanding scientific collaboration. In Addition, demonstration events such as
Fields of Innovation and Open Labs are aimed at local farmers, breeders, advisors, and seed
companies, helping translate research into practice
Variability of vitamin E content in ZP popcorn hybrids
No full textVitamin E is a group of eight lipid-soluble antioxidants found in plants, divided into tocopherols and tocotrienols. As an essential nutrient, it supports seed development, stress response, and membrane protection. In humans, it helps protect cell membranes and may reduce the risk of diseases such as Alzheimer's, cancer, neurological disorders and inflammation. Both tocopherols and tocotrienols exist in four isoforms: α (alpha), β (beta), γ (gamma), and δ (delta), classified based on the position of methyl groups on the chromanol ring. This study analyzed α, γ+β, and δ tocopherols (T) and tocotrienols (T3) in five popcorn hybrids grown in Zemun Polje (ZP) and Kruševac (KŠ), Serbia. The content of vitamin E was higher in Zemun Polje, indicating that environmental factors had a significant impact on the content. The average content of α-T was 5.31 μg/g dry weight (DW) at ZP and 4.27 μg/g DW at KŠ, with ranges of 3.99–7.52 μg/g DW and 3.18–5.03 μg/g DW, respectively. The highest α-T content at both locations was recorded in hybrid ZP 6119k. The average content of γ+β-T was 29.63 μg/g DW at ZP and 23.51 μg/g DW at KŠ. δ-T content ranged from 1.69–3.63 μg/g DW at ZP and from 0.89–2.25 μg/g DW at KŠ. The highest α-T3 content at both locations was found in hybrid ZP 614k (5.21 μg/g DW at ZP and 3.62 μg/g DW at KŠ). γ+β-T3 varied from 4.13–7.07 μg/g DW (ZP) and 3.29–6.99 μg/g DW (KŠ). The highest values of δ-T3 were 0.74 μg/g DW in ZP 6153k (ZP) and 0.76 μg/g DW in ZP 6119k and ZP 6170k (KŠ). Popcorn hybrids with higher Vitamin E content, especially ZP 6119k, show potential as functional foods with added health benefits for human consumption
Enhancing understanding of white maize inbred lines genetic structure by leveraging SNP markers

No full textIntroduction: Earlier sowing is a promising strategy of ensuring sufficiently high maize yields in the face of negative environmental factors caused by climate change. However, it leads to the low temperature exposure of maize plants during emergence, warranting a better understanding of their response and acclimation to suboptimal temperatures.
Materials and Methods: To achieve this goal, whole transcriptome sequencing was performed on two maize inbred lines – tolerant/susceptible to low temperatures, at the 5-day-old seedling stage. Sampling was performed after 6h and 24h of treatment (10/8°C). The data was filtered, mapped, and the identified mRNAs, lncRNAs, and circRNAs were quantified. Expression patterns of the RNAs, as well as the interactions between them, were analyzed to reveal the ones important for low-temperature response.
Results and Discussion: Genes involved in different steps of photosynthesis were downregulated in both genotypes: psa, psb, lhc, and cab genes important for photosystem I and II functioning, as well as rca, prk, rbcx1 genes necessary for the Calvin cycle. The difference in low-temperature tolerance between genotypes appeared to arise from their ability to mitigate damage caused by photoinhibition: ctpa2, grx, elip, UF3GT genes showed higher expression in the tolerant genotype. Certain identified lncRNAs also targeted these genes, creating an interaction network induced by the treatment (XLOC_016169-rca; XLOC_002167-XLOC_006091-elip2). These findings shed light on the potential mechanisms of low-temperature acclimation during emergence and lay the groundwork for subsequent analyses across diverse maize genotypes and developmental stages. As such, it offers valuable guidance for future research directions in the molecular breeding of low-temperature tolerant maize
