Special Issue Information

Dear Colleagues,

At the global level, the most important crops for producing human food are wheat and other cereals.

Today, more than ever, due to global climatic and political difficulties, scientists need to make more effort to select drought-tolerant, disease-resistant and, at the same time, productive cereals that are able to satisfy worldwide needs.

The Carlotta Award is dedicated to young female researchers working on wheat and related issues. The first edition of this prize was in 2018, the year of the 150th anniversary of the birth of Carlotta Parisani Strampelli, wife and assistant to the great Italian geneticist Nazzareno Strampelli.

In 1903, she followed her husband to Rieti with their two-year-old daughter and whilst expecting their second child. In doing so, Carlotta accepted a life and a destiny that could be considered too humble for a noblewoman. During that time, she worked to improve the performance of hybridization, acquiring fine dexterity and perfect skill in the ‘artificial pollination’ of grains. Carlotta Parisani acted as a "trailblazer" for all women, at first as a technical assistant and then as a researcher.

For these reasons, it was decided to name the award after her, to give due recognition to women in the service of research, bearing in mind the difficulties that women have even today, and to give a positive signal to young female researchers engaged in the genetic improvement of wheat and other cereals. It was time to acknowledge her value through this public award and greater recognition.

While the Carlotta Award first edition, with the participation of the Accademia delle Scienze detta dei XL, was held in Rome, in the framework of an ad hoc International Conference entitled “Wheats & Women” the second edition, 2022, will be hosted in Bologna, during the most important International Congress on cereals and derived food products, "From Seed to Pasta IV".

In the present edition, we have included a second theme specifically related to the production, safety and healthiness of the food chain linked to wheat. The themes for the two awards, in line with the topics of the host Congress, are therefore:

  1. Wheat genetics, genomics and breeding;
  2. Sustainable wheat production for food security, food quality and safety, and durum wheat-pasta value chain.

The present Special Issue (SI) is therefore focused on wheats and is dedicated to female scientists working in these research areas, with a view to highlighting the work of young female researchers and improving the knowledge and technologies surrounding this crop, essential for the planet and all human populations.

Besides the Carlotta Award Winners, we have decided to give some other female scientists a “special mention”, as they are considered excellent, in spite of not having publications with a high IF and/or significant funding for their scientific work. These special mentions are aimed at rewarding the quality and novelty of the research carried out by female scientists working in developing and/or emerging countries.

In the quest for sustainable and nutritious food sources, exploration of ancient grains and wild relatives of cultivated cereals has gained attention. Aegilops caudata, a wild wheatgrass species, stands out as a promising genetic resource due to its potential for crop enhancement and intriguing nutritional properties. This manuscript investigates the CslF6 gene sequence and protein structure of Aegilops caudata, employing comparative analysis with other grass species to identify potential differences impacting β-glucan content. The study involves comprehensive isolation and characterization of the CslF6 gene in Ae. caudata, utilizing genomic sequence analysis, protein structure prediction, and comparative genomics. Comparisons with sequences from diverse monocots reveal evolutionary relationships, highlighting high identities with wheat genomes. Specific amino acid motifs in the CslF6 enzyme sequence, particularly those proximal to key catalytic motifs, exhibit variations among monocot species. These differences likely contribute to alterations in β-glucan composition, notably impacting the DP3:DP4 ratio, which is crucial for understanding and modulating the final β-glucan content. The study positions Ae. caudata uniquely within the evolutionary landscape of CslF6 among monocots, suggesting potential genetic divergence or unique functional adaptations within this species. Overall, this investigation enriches our understanding of β-glucan biosynthesis, shedding light on the role of specific amino acid residues in modulating enzymatic activity and polysaccharide composition.

Farmers in northern and central Indian regions prefer to plant wheat early in the season to take advantage of the remaining soil moisture. By planting crops before the start of the season, it is possible to extend the time frame for spring wheat. The early-wheat-establishment experiment began in the 2017 growing season at the Borlaug Institute for South Asia (BISA) in Ludhiana, India, and, after three years of intensive study, numerous agronomic, physiological, and yield data points were gathered. This study aimed to identify wheat lines suitable for early establishment through an analysis of the agro-morphological traits and the genetic mapping of associated genes or quantitative trait loci (QTLs). Advancing the planting schedule by two–three weeks proved to be advantageous in terms of providing a longer duration for crop growth and reducing the need for irrigation. This is attributed to the presence of residual soil moisture resulting from the monsoon season. Early sowing facilitated the selection of genotypes able to withstand early elevated temperatures and a prolonged phenological period. The ideotype, which includes increased photo-growing degree days for booting and heading, as well as a longer grain-filling period, is better suited to early planting than timely planting. Senescence was delayed in combination with a slower rate of canopy temperature rise, which was an excellent trait for early-adapted ideotypes. Thus, a novel approach to wheat breeding would include a screening of genotypes for early planting and an ideotype design with consistent and appropriate features. A genome-wide association study (GWAS) revealed multiple QTLs linked to early adaptation in terms of the yield and its contributing traits. Among them, 44 novel QTLs were also found along with known loci. Furthermore, the study discovered that the phenology regulatory genes, such as Vrn and Ppd, are in the same genomic region, thereby contributing to early adaptation. Full article
