Tartary buckwheat is a kind of plant which can be used as medicine as well as edible. Abscisic acid (ABA) signaling plays an important role in the response of plants such as tartary buckwheat to drought and other stress. However, there are not many studies on tartary buckwheat by ABA treatment. In this study, the germination, root length, stoma, and anthocyanin accumulation of tartary buckwheat were all significantly affected by ABA. ABA signaling is important for plants to respond to drought and other stresses, the bZIP gene family is an important member of the ABA signaling pathway. Through the analysis of the origin relationship between tartary buckwheat bZIP family and its related species, 19 bZIP genes in tartary buckwheat were found to be relatively conserved, which laid a foundation for further study of bZIP family. The qRT-PCR results showed that most of the group members were induced by ABA treatment, including 0, 15, 30, 50, 70 µM ABA and 0, 0.5, 2, 4, 8, 16, 24 h ABA treatment. These results suggested that ABA could affect the growth and development of tartary buckwheat, and FtbZIPs might have different functions in the response of tartary buckwheat to drought. This study will be helpful to further analyze the genetic breeding and economic value of tartary buckwheat resistance.

Tartary buckwheat (Fagopyrum tataricum), a functional grain known for its medicinal and nutritional properties, has garnered significant attention due to its high flavonoid content and unique health benefits. Heat stress during the flowering stage can lead to sterility in Tartary buckwheat, resulting in reduced yields. This study investigates the effects of a treatment (30/27 °C for 7 days) on flower development, fertility, stress physiology, and gene expression in Tartary buckwheat, while also validating the efficacy of hormone treatments in alleviating the negative effects of heat stress.

Tartary buckwheat is a nutrient-rich pseudo-cereal whose starch contents, including amylose and amylopectin contents, and their properties hold significant importance for enhancing yield and quality. The granule-bound starch synthase (GBSS) is a key enzyme responsible for the synthesis of amylose, directly determining the amylose content and amylose-to-amylopectin ratio in crops. Although one has already been cloned, the genes at the genome-wide level have not yet been fully assessed and thoroughly analyzed in Tartary buckwheat.

Background: Tartary buckwheat is a plant recognized for its resistance to various environmental stresses. Due to its valuable source of phenolic compounds, is also characterized as a medicinal plant; therefore, the aim of this study was to investigate the drought stress for the levels of phenolic compounds in the morphological parts of the plant.
Methods: This experiment was conducted in 7 L pots under laboratory conditions.

Background: Due to the totipotency of plant cells, which allows them to reprogram from a differentiated to a dedifferentiated state, plants exhibit a remarkable regenerative capacity, including under in vitro culture conditions. When exposed to plant hormones, primarily auxins and cytokinins, explant cells cultured in vitro can undergo differentiation through callus formation. Protoplast culture serves as a valuable research model for studying these processes in detail.
