GmERF13 mediates salt inhibition of nodulation through interacting with GmLBD16a in soybean

Nature Communications, Год журнала: 2025, Номер 16(1)

Опубликована: Янв. 6, 2025

While the genetic regulation of nodule formation has been well explored, molecular mechanisms by which abiotic stresses, such as salt stress, impede remain largely elusive. Here, we identify four APETALA2/Ethylene Responsive Factor (AP2/ERF) transcription factors, GmERF13s, that are induced stress and play key roles in salt-repressed nodulation. Loss GmERF13 function increases density, while its overexpression suppresses Moreover, stress-inhibited is greatly attenuated loss-of-function mutants, whereas it becomes more pronounced when overexpressed. Furthermore, GmERF13s can interact with Lateral Organ Boundaries Domain 16 (GmLBD16a), attenuates GmLBD16a's binding capacity on Expansin17c (GmEXP17c) promoter. Additionally, salt-induced expression relies abscisic acid signaling, direct promotion facilitated GmABI5, illustrating their involvement enhancing expression. Collectively, our study reveals a mechanism impedes nodulation through GmERF13-GmLBD16a-GmEXP17 module soybean. Salt inhibits legume Here reported mutants factor gene alleviate this inhibitory effect. Further investigations reveal regulated regulates formation.

Опубликована: Фев. 24, 2024

In recent days, there has been a noticeable surge in demand for high-quality rice. However, the influences of salinity on quality and starch properties rice remain unclear. Three cultivars (Nanjing 9108, Nanjing 5055, 46) were studied to investigate responses grain salt stress. There three treatments, including control zero level (0 g·kg−1, CK), two levels 0.1 g·kg−1 (0.1% stress, T1) 0.2 (0.2% T2). The study involved assessment appearance, milling, cooking, eating qualities We also conducted an analysis pasting properties, evaluation thermal examination fine structure amylopectin. findings suggest that as stress increases, yield gradually declines, which is primarily due significant reduction total spikelet number ratio filled grains. Compared with CK treatment, appearance milling significantly improved within T1 treatment. addition, protein concentration amylose decreased, gel consistency was increased, cooking improved. terms peak viscosity, breakdown value, infrared (1022/995), short-chain-length amylopectin increased significantly, while setback temperature, gelatinization enthalpy, relative crystallinity, (1045/1022) decreased significantly. When comparing T2 CK, had deteriorated, changes structural physicochemical opposite those comparison between treatment group. Accordingly, we propose moderate potential enhance quality, even though may be slight decrease yield. This indicates it feasible cultivate saline–alkali beach areas.

Abstract Saline water could affect the structural and physicochemical properties of starch rice ( Oryza sativa L.) quality. In present study, two high‐quality hybrid varieties, that is, Y Liangyou 957 (YLY957) Jing 534 (JLY534), were grown in a mixture underground sea having 0, 5, 11 dS m −1 electrical conductivity (EC). The mixtures applied at active tillering stage. Results showed application saline decreased total amylose content increased protein content, thus reduced taste value. addition, B2 chain amylopectin by 3.83%–5.30% under water, leading to delayed pasting higher gelatinization temperature. Application also altered relative crystallinity, which affected surface smoothness granules (increased percentage small medium [ d < 10 μm]). Overall, results indicated salt stress during whole growth period changed structure eating cooking qualities.

Combining Controlled-Release and Normal Urea Enhances Rice Grain Quality and Starch Properties by Improving Carbohydrate Supply and Grain Filling

Plants, Год журнала: 2025, Номер 14(1), С. 107 - 107

Опубликована: Янв. 2, 2025

Controlled-release nitrogen fertilizers are gaining popularity in rice (Oryza stavia L.) cultivation for their ability to increase yields while reducing environmental impact. Grain filling is essential both the yield and quality of rice. However, impact controlled-release fertilizer on grain-filling characteristics, as well relationship between these characteristics quality, remains unclear. This study aimed identify key influencing milling appearance, cooking eating qualities, physicochemical properties starch. In this study, a two-year field experiment was conducted that included four management practices: zero input (CK), local high-yield practice with split urea applications (100% urea, CU), single basal application 100% (CRNF), blend 70% 30% (CRNF-CU). The results showed sufficient amount carbohydrates process, indicated by higher sugar–spikelet ratio, improving grain quality. An increased ratio enhances resulting an elevated average rate (Gmean) peak (Gmax), also overall time required (D). Compared CU, CRNF CRNF-CU treatments did not significantly change but reduced chalky kernel chalkiness, thereby enhancing appearance These amylose amylopectin contents protein content, though proportion constituents remained unchanged. led larger starch granules notably smoother surfaces. Additionally, relative crystallinity structural order, increasing amorphous structure outer region granules, which lowered crystal stability. viscosity improved thermodynamic starch, enhanced conclusion, most effective strategy enhance ensures adequate carbohydrate supply filling, efficient

Here, we investigated physiological responses, yield components, starch properties, and biosynthesis genes in five Thai rice (Oryza sativa L.) cultivars (SPR1, Hawm Daeng, RD43, RD69, PTT1) with distinct characteristics under salt stress. Salt stress decreased flag leaf greenness (SPAD), normalized difference vegetation index (NDVI) levels, carotenoid reflectance 1 (CRI1) levels all cultivars, resulting reduced net photosynthesis, transpiration rates, components across Daeng PTT1 being most susceptible. In contrast, RD69 SPR1 were more tolerant, exhibiting recovered chlorophyll fluorescence total performance values after 3 days. apparent amylose content (AAC) increased rapidly available glucose (RAG) cultivars. Granule-bound synthase I (GBSSI) expression declined the Daeng. SPAD, NDVI, CRI1, photosynthetic parameters correlated GBSSI at milky dough stages of grain development. showed little to no correlation slowly but resistant booting stage affected quality, variations depending on susceptibility, which turn during
