Production of homozygous transgenic plants is a prerequisite for the phenotypic analysis and/or for the commercial release of transgenic plants for cultivation. Here we present a simple protocol for the selection of homozygous transgenics using antibiotics as a selectable marker. The protocol has been used to select homozygous rice transgenic plants using hygromycin antibiotic. However, the described protocol can be used for selction of homozygous in any transgenic plants using a appropriate selectable marker. For complete details on the use and execution of this protocol, please refer to Passricha et al. (2016)..

Nuclear factor Y (NF-Y) is an evolutionarily conserved heterotrimeric transcription factor in eukaryotes. In a previous study, OsNF-YB12 was confirmed to be associated with drought tolerance using the Ecotilling method. In this study, real-time quantitative RT-PCR revealed that OsNF-YB12 was induced by various abiotic stresses and phytohormones, with expression levels differing between leaves and roots.

During cold acclimation in high-latitude and high-altitude regions, japonica rice develops enhanced cold tolerance, but the underlying genetic basis remains unclear. Here, we identify CTB5, a homeodomain-leucine zipper (HD-Zip) transcription factor that confers cold tolerance at the booting stage in japonica rice. Four natural variations in the promoter and coding regions enhance cold response and transcriptional regulatory activity, enabling the favorable CTB5 allele to improve cold tolerance.

The exogenous application of RNAi technology offers new promises for crops improvement. Cell-based or synthetically produced strands are economical, non-transgenic and could induce the same responses. The substantial population growth demands novel strategies to produce crops without further damaging the environment.

Coronaviruses continue to disrupt health and economic productivity worldwide. Porcine epidemic diarrhea virus (PEDV) is a devastating swine disease and SARS-CoV-2 is the latest coronavirus to infect the human population. Both viruses display a similar spike protein on the surface that is a target of vaccine development.

The frequent occurrence of extreme weather conditions in the world has brought many unfavorable factors to plant growth, causing the growth and development of plants to be hindered and even leading to plant death, with abiotic stress hindering the growth and metabolism of plants due to severe uncontrollability. The WHY1 transcription factor plays a critical role in regulating gene expression in plants, influencing chlorophyll biosynthesis, plant growth, and development, as well as responses to environmental stresses. The important role of the gene in regulating plant growth and adaptation to environmental stress has become a hot research topic.
