The nitrogen-fixing symbiosis between Sinorhizobium meliloti and its leguminous host plant Medicago truncatula occurs in a specialized root organ called the nodule. Bacteria that are released into cells surrounded by unique membrane compartment termed symbiosome. We found symbiosis-defective dnf1 mutant of M. truncatula, bacteroid symbiosome development blocked. identified DNF1 gene as encoding subunit signal peptidase complex is highly expressed nodules. By analyzing data from whole-genome...
In the nitrogen-fixing symbiosis between legume hosts and rhizobia, bacteria are engulfed by a plant cell membrane to become intracellular organelles. model Medicago truncatula, internalization differentiation of Sinorhizobium (also known as Ensifer) meliloti is prerequisite for nitrogen fixation. The host mechanisms that ensure long-term survival differentiating (bacteroids) in this unusual association unclear. M. truncatula defective fixation4 (dnf4) mutant unable form productive...
Significance The legume–rhizobial symbiosis culminates in the formation of nitrogen-fixing root nodules. This symbiotic relationship plays a critical role sustainable agriculture because it reduces need for nitrogen fertilizers. However, fixation efficiency varies tremendously between different plant–bacteria combinations, and molecular mechanisms that regulate this specificity are not well understood. We report is regulated by nodule-specific cysteine-rich (NCR) peptides Medicago truncatula...
SUMMARY In higher plants, the generation and release of viable pollen from anthers is vital for double fertilization initiation seed development. Thus, characterization genes related to development anther dehiscence in plants great significance. The F‐box protein COI1 plays a crucial role jasmonate (JA) signaling pathway interacts with many JAZ family proteins presence jasmonoyl‐isoleucine (JA‐Ile) or coronatine (COR). mutation AtCOI1 Arabidopsis leads defective male sterility (MS), although...
Temperature has an important influence on plant growth and development. In protected agriculture production, accurate prediction of temperature environment is great significance. However, due to the time series, nonlinear multi coupling characteristics temperature, it difficult achieve prediction. We proposed a method for building solar greenhouse model based timeseries analysis, that considers series dynamic changes in system. The would predict greenhouse, provide reference change law...
Rhizobia establish a symbiotic relationship with their host legumes to induce the formation of nitrogen-fixing nodules. This process is regulated by many rhizobium regulators, including some two-component regulatory systems (TCSs). NtrY/NtrX, TCS that was first identified in Azorhizobium caulinodans, required for free-living nitrogen metabolism and nodulation on Sesbania rostrata. However, its functions typical such as Sinorhizobium meliloti remain unclear. Here we found S. response...
Plants use receptor-like kinases to monitor environmental changes and transduce signals into plant cells. The Medicago truncatula (hereafter M. truncatula) DOES NOT MAKE INFECTIONS2 (DMI2) protein functions as a coreceptor of rhizobial initiate nodule development infection during nitrogen-fixing symbiosis, but the mechanisms regulating DMI2 level folding are still unknown. Here, we report that abundance symbiosis. accumulates in nodules is induced by rhizobia treatment through...
Summary Arbuscular mycorrhizal (AM) symbiosis relies on the formation of arbuscules for efficient nutrient exchange between plants and AM fungi. In this study, we identified a novel kinase gene in rice named OsADK1 ( Arbuscule Development Kinase 1 ) that is required arbuscule development. By obtaining OsADK1pro :: GUS transgenic also generating Osadk1 mutants via CRISPR/Cas9 technique, was revealed to be specifically induced arbusculated cortical cells mutations resulted an extremely low...
Plants possess two cryptochrome photoreceptors, 1 (CRY1) and 2 (CRY2), that mediate overlapping distinct physiological responses. Both CRY1 CRY2 undergo blue light-induced phosphorylation, but the molecular details of phosphorylation remain unclear. Here we identify 19 in vivo sites using mass spectrometry systematically analyze photobiochemical activities variants with phosphosite substitutions. We demonstrate nonphosphorylatable have impaired degradation, functions, whereas phosphomimetic...
Glutathione, a key antioxidant in Sinorhizobium meliloti, is required for the development of alfalfa (Medicago sativa) nitrogen-fixing nodules. This tripeptide can be synthesized by both γ-glutamyl cysteine synthetase (GshA) and glutathione (GshB) Escherichia coli S. meliloti. Genetic evidence has indicated that null mutant meliloti gshA or gshB1 does not establish efficient symbiosis on alfalfa. However, transcriptional regulation gshB been well understood. Here, LsrB, member LysR family...
Phenotypic changes caused by postharvest deterioration of the quality attributes apples cause substantial economic losses. Thus, strategies for accurate prediction shelf life is urgently needed. In each three consecutive years from 2016 to 2018, freshly harvested 'Royal Gala' were stored at 0, 5, 15, and 25°C, respectively. Subsequently, 11 measured periodic intervals until end storage. To screen fewer more useful indexes, input datasets considered: temperature, color value (L*, a*, b*, △E,...
