Abstract
Genetically enhancing drought tolerance and nutrient use efficacy enables sustainable and stable wheat production in drought-prone areas exposed to water shortages and low soil fertility, due to global warming and declining natural resources. In this study, wheat plants, exhibiting improved drought tolerance and N-use efficacy, were developed by introducing GmTDN1, a gene encoding a DREB-like transcription factor, into two modern winter wheat varieties, cv Shi4185 and Jimai22. Overexpressing GmTDN1 in wheat resulted in significantly improved drought and low-N tolerance under drought and N-deficient conditions in the greenhouse. Field trials conducted at three different locations over a period of 2-3 consecutive years showed that both Shi4185 and Jimai22 GmTDN1 transgenic lines were agronomically superior to wild-type plants, and produced significantly higher yields under both drought and N-deficient conditions. No yield penalties were observed in these transgenic lines under normal well irrigation conditions. Overexpressing GmTDN1 enhanced photosynthetic and osmotic adjustment capacity, antioxidant metabolism, and root mass of wheat plants, compared to those of wild-type plants, by orchestrating the expression of a set of drought stress-related genes as well as the nitrate transporter, NRT2.5. Furthermore, transgenic wheat with overexpressed NRT2.5 can improve drought tolerance and nitrogen (N) absorption, suggesting that improving N absorption in GmTDN1 transgenic wheat may contribute to drought tolerance. These findings may lead to the development of new methodologies with the capacity to simultaneously improve drought tolerance and N-use efficacy in cereal crops to ensure sustainable agriculture and global food security.

Abstract
Soybean is the main economic crop, and also the main source of oil and protein for human consumption. Drought stress has a great influence on the growth and yield of soybean crops. Therefore, improving the drought resistance of soybean, especially drought resistance in the field, is important to increase soybean yield. AP2/ERF (APETALA2/ethylene responsive factor) transcription factors are one of the largest families of transcription factors in plants. However, there has been little research on the value of applying DREB (dehydration-responsive element-binding)-like genes in improving the drought resistance of soybean. Here, we further study the value of the application of GmDREB1 in soybean. The results of drought resistance identification in the field and greenhouse showed that the overexpression of GmDREB1 could significantly enhance the drought resistance of transgenic soybean, and the yield was clearly higher than that of the wild type. GmDREB1 has transcriptional activity and is located in the nucleus. For mechanism analysis of GmDREB1 in soybean, two ERF-like transcription factors, GmERF008 and GmERF106, were shown to interact with GmDREB1 using yeast two-hybrid (Y2H) and bimolecular fluorescence complementary (BiFC) experiments. qRT-PCR (quantitative real-time PCR) results showed that the expression of many stress-related genes in GmDREB1 transgenic soybean were significantly up-regulated compared with the WT under a drought environment. In conclusion, GmDREB1 can regulate the expression of downstream stress-related genes by forming a heterodimer with ERF-like transcription factors, which can improve the drought resistance of transgenic soybean.

Abstract
Drought-response-element binding (DREB)-like transcription factors can significantly enhance plant tolerance to water stress. However, most research on DREB-like proteins to date has been conducted in growth chambers or greenhouses, so there is very little evidence available to support their practical use in the field. In this study, we overexpressed GmDREB1 from soybean in two popular wheat varieties and conducted drought-tolerance experiments across a range of years, sites, and drought-stress regimes. We found that the transgenic plants consistently exhibited significant improvements in yield performance and a variety of physiological traits compared with wild-type plants when grown under limited water conditions in the field, for example showing grain yield increases between 4.79-18.43%. Specifically, we found that the transgenic plants had reduced membrane damage and enhanced osmotic adjustment and photosynthetic efficiency compared to the non-transgenic controls. Three enzymes from the biosynthetic pathway of the phytohormone melatonin were up-regulated in the transgenic plants, and external application of melatonin was found to improve drought tolerance. Together, our results demonstrate the utility of transgenic overexpression of GmDREB1 to improve the drought tolerance of wheat in the field.
