AB  - Assimilated carbon during vegetative and early reproductive growth in wheat is temporarily stored in stem internodes and leaf sheaths (LSs), and can later be remobilized and transported to developing grain. The present study was undertaken to determine the effect of several peduncle (the uppermost internode) morpho-anatomical and biochemical traits on grain weight, and to assess the contribution of the peduncle water-soluble carbohydrate (WSC) reserves shortly after anthesis to its variation. In 2-year field trials, 61 wheat genotypes were used (27 F-4:5 families, 17 parents used for the crosses and the 17 current best standards), comparing intact control plants (CP) with plants that were defoliated (DP) by cutting off all leaf blades 10 days after anthesis. Estimated contributions of peduncle (culm (C) and flag LS) assimilate reserves to grain weight/spike were from 006 to 031 and from 011 to 045 in CP and DP plants, respectively. In both CP and DP plants, a higher contribution was from the LS than from the C. High peduncle reserve mobilization efficiency, a longer exposed part of the peduncle and larger C storage capacity (through higher parenchyma and/or lower lignified area) were of specific benefit for maintaining grain weight in defoliated plants. F-4:5 families had higher transport capacity in the peduncle, but without any improvement in WSC-related traits compared with the best standards.

AB  - As one of the most important agricultural crops, maize is a staple diet for a large portion of the continuously growing world's human population. Unfortunately, its production is severely affected by adverse environmental stresses such as drought, salt, low and high temperatures. The mechanisms of drought stress tolerance in maize are quite complex and involves a signaling network of genes that controls its adaptation to the stress. Recently, many transcription factors (TFs) for tolerance to drought stress have been identified in maize. In this study, specifically designed primers were used to identify functional single nucleotide polymorphisms (SNPs) in the MYB-like protein E1 (MYBE1) gene of 26 tolerant and sensitive maize inbred lines from the gene banks of Maize Research Institute "Zemun Polje", Serbia and Maize Research Institute, Kneja, Bulgaria by PCR amplification and direct sequencing. Multiple alignments of the sequenced fragments to the drought sensitive US maize inbred B73 and other inbred lines, representing the functional diversity of maize, from the Panzea database (http://www.panzea.org/) was performed. The sequence alignment revealed several SNPs in inbred lines object of this study, one of which unique to the drought tolerant Serbian inbreds T3, T5, T6, T7 and T8. In these lines, the A→G transition, located in the acidic Ser/Thr - rich region of the gene, leads to amino acid change from Tryptophan to Alanine at the corresponding position of the protein. This replacement does not affect the binding site of MYBE-1 transcription factor, but possibly reflects the spatial conformation through changing of its functional activity. This study will contribute the identification of functional markers in genes implicated in the development of drought stress tolerance and their further use for genomic improvement in the national maize selection programs.
