“…Protein contents were determined using an Enhanced BCA Protein Assay Kit (Beyotime, Shanghai, China). The activities of antioxidant enzymes, including catalase (CAT) and ascorbate peroxidase (APX), were measured as described previously (Rao et al, 1996; Li et al, 2011; Tian et al, 2014). The assay of enzyme activity was carried out using a spectrophotometer at 25°C.…”

Drought is a major abiotic stress that limits wheat production worldwide. To ensure food security for the rapidly increasing world population, improving wheat yield under drought stress is urgent and relevant. In this study, an RNA-seq analysis was conducted to study the effect of drought on wheat transcriptome changes during reproductive stages under field conditions. Our results indicated that drought stress during early reproductive periods had a more severe impact on wheat development, gene expression and yield than drought stress during flowering. In total, 115,656 wheat genes were detected, including 309 differentially expressed genes (DEGs) which responded to drought at various developmental stages. These DEGs were involved in many critical processes including floral development, photosynthetic activity and stomatal movement. At early developmental stages, the proteins of drought-responsive DEGs were mainly located in the nucleus, peroxisome, mitochondria, plasma membrane and chloroplast, indicating that these organelles play critical roles in drought tolerance in wheat. Furthermore, the validation of five DEGs confirmed their responsiveness to drought under different genetic backgrounds. Functional verification of DEGs of interest will occur in our subsequent research. Collectively, the results of this study not only advanced our understanding of wheat transcriptome changes under drought stress during early reproductive stages but also provided useful targets to manipulate drought tolerance in wheat at different development stages.

“…For example, plants deficient in the expression of proteasome subunits (Li et al ), E3 ligases, and autophagy‐related genes (Zhou et al , ; Liu et al ; Gil et al ) are susceptible to HS. Moreover, transgenic plants overexpressing genes encoding either ubiquitin (Tian et al ) or ubiquitin E3 ligases (Lim et al ; Liu et al ; Liu et al ) exhibit enhanced basal and/or acquired heat tolerance.…”

The increased prevalence of high temperatures (HTs) around the world is a major global concern, as they dramatically affect agronomic productivity. Upon HT exposure, plants sense the temperature change and initiate cellular and metabolic responses that enable them to adapt to their new environmental conditions. Decoding the mechanisms by which plants cope with HT will facilitate the development of molecular markers to enable the production of plants with improved thermotolerance. In recent decades, genetic, physiological, molecular, and biochemical studies have revealed a number of vital cellular components and processes involved in thermoresponsive growth and the acquisition of thermotolerance in plants. This review summarizes the major mechanisms involved in plant HT responses, with a special focus on recent discoveries related to plant thermosensing, heat stress signaling, and HT-regulated gene expression networks that promote plant adaptation to elevated environmental temperatures.

“…Among the cellular processes, protein ubiquitination is a key process that plays 577 an important role in plant adaptation to abiotic stress. Over-expression of the wheat Ta-Ub gene in 578 tobacco was found to confer resistance to drought (Guo et al, 2008) and heat (Tian et al, 2014) stresses, 579 demonstrating the role of Ta-UB in plant stress tolerance in dicots. However, little is known about its role 580 in monocots.…”

The genus Brachypodium represents a model system that is advancing our knowledge of the biology of grasses, including small grains, in the post-genomics era. The most widely used species, Brachypodium distachyon, is a C3 plant that is distributed worldwide. Brachypodium distachyon has a small genome, short lifecycle, and small stature and is amenable to genetic transformation. Due to the intensive and thoughtful development of this grass as a model organism, it is well-suited for laboratory and field experimentation. The intent of this review is to introduce this model system genus and describe some key outcomes of nearly a decade of research since the first draft genome sequence of the flagship species, B. distachyon, was completed. We discuss characteristics and features of B. distachyon and its congeners that make the genus a valuable model system for studies in ecology, evolution, genetics, and genomics in the grasses, review current hot topics in Brachypodium research, and highlight the potential for future analysis using this system in the coming years.
