Understanding the genetic architecture of drought tolerance is of great importance for overcoming the negative impact of drought on wheat yield. Earlier, we discovered the critical role of chromosome 2A for the drought-tolerant status of wheat spring cultivar Saratovskaya 29. A set of 92 single-chromosome recombinant double haploid (SCRDH) lines were obtained in the genetic background of Saratovskaya 29.

Article Synopsis
- Transgenic technologies are key tools in biotechnology, allowing for targeted genetic modifications that can uncover gene functions and alter plant metabolic pathways.
- Proper design of chimeric gene constructs is crucial for effective modification, particularly in the choice of promoters that regulate transgene expression.
- The TGP database has been created to gather information on various noncanonical tissue-specific and developmentally regulated promoters, providing resources for optimizing transgene control in plants.
Article Synopsis
- Transgenic plant experiments often need specific promoters to achieve the right gene expression, but the commonly used promoters offer limited options and can cause issues like transgene silencing.
- To tackle these challenges, researchers can utilize various plant gene promoters with proven effects, though this requires extensive literature review.
- The TransGene Promoters (TGP) database provides a centralized resource of genomic DNA segments that deliver specific expression patterns for transgenic plants, complete with an easy-to-use search interface.
Light regulates almost all physiological and biochemical processes in plants. Plants react to quantitative and qualitative light characteristics owing to the system of photoreceptors and a branched network for light signal transduction. Comprehensible visual representations of gene networks using of filter technology in the GeneNet system assist understanding the types of the relationships between the components inside the networks and to define their hierarchical structure.
