Abstract:
... Co-exposure to heavy metal and antibiotic pollution might result in complexation and synergistic interactions, affecting rice growth and further exacerbating pollutant enrichment. Therefore, our study sought to clarify the influence of different Tetracycline (TC) and Cadmium(Cd) concentration ratios (both alone and combined) on rice growth, pollutant accumulation, and transportation during the til ...

Abstract:
... The pollutants have become ubiquitous in the total environment (water, soil and air) due to human activities and they are hazardous to all forms of life on the earth. This problem has made scientists focus on mitigating or complete reduction in pollutants by several means. Microorganism and plants are known to scavenge pollutants. Both are studied enormously in reducing, refining, and removing pol ...

Abstract:
... Nitrogen (N) is an essential element for rice (Oryza sativa L.) growth. Rice responds to N-limiting conditions by changing root morphology. Strigolactones (SLs) and auxin modulate rice root elongation under N-deficient conditions. However, the interactions between SLs and auxin in the regulation of root elongation in response to N deficiency remain needing further study. Here, we analysed the func ...

Abstract:
... The eco-compatibility of the glycine-derived polyamidoamine M-GLY, chosen as the benchmark for water-soluble polyamidoamines, was investigated by means of the seed germination test using watercress seeds. The percent germinated seeds and their root elongation were measured, and the corresponding germination index (GI) calculated for each set of data obtained by incubating the seeds with M-GLY aque ...

Abstract:
... BACKGROUND: The bermudagrass (Cynodon dactylon (L.) Pers) roots responded differently in terms of morphological and anatomical characteristics under diverse submergence conditions, and they developed aerenchyma under non-flooding condition. In order to understand these mechanisms, bermudagrass cuttings were used as experimental material to examine their biomass, root morphology, and aerenchyma for ...

Abstract:
... Root cap not only protects root meristem, but also detects and transduces the signals of environmental changes to affect root development. The symplastic communication is an important way for plants to transduce signals to coordinate the development and physiology in response to the changing enviroments. However, it is unclear how the symplastic communication between root cap cells affects root gr ...

Abstract:
... MAIN CONCLUSION: This minireview details the impact of iron–phosphate and zinc–phosphate interactions in plants and provides perspectives for further areas of research regarding nutrient homeostasis. Iron (Fe) and zinc (Zn) are among the most important micronutrients for plant growth and have numerous implications for human health and agriculture. While plants have developed efficient uptake and t ...

Abstract:
... CELL DIVISION CONTROL PROTEIN48 (CDC48) is essential for membrane fusion, protein degradation, and other cellular processes. Here, we revealed the crucial role of CDC48B in regulating periclinal cell division in roots by analyzing the recessive gen1 mutant. We identified the GEN1 gene through map‐based cloning and verified that GEN1 encodes CDC48B. gen1 showed severely inhibited root growth, incre ...

Abstract:
... Rhizosphere microorganisms interact with plant roots by producing chemical signals that regulate root development. However, the distinct bioactive compounds and signal transduction pathways remain to be identified. Here, we showed that sesquiterpenes are the main volatile compounds produced by plant‐beneficial Trichoderma guizhouense NJAU4742. Inhibition of sesquiterpene biosynthesis eliminated th ...

Abstract:
... Plant branch and root growth relies on metabolism of the strigolactone (SL) hormone. The interaction between the SL molecule, Oryza sativa DWARF14 (D14) SL receptor, and D3 F-box protein has been shown to play a critical role in SL perception. Previously, it was believed that D3 only interacts with the closed form of D14 to induce downstream signaling, but recent experiments indicate that D3, as w ...

The aim of this study was to disentangle the effects of the factors mucilage and soil moisture on a range of soil mechanical parameters in a sand and a loam. Both substrates were homogenised and filled into cylinders at bulk densities (ρb) of 1.26 and 1.47 g cm⁻³ for loam and sand, respectively. Chi ...

Abstract:
... Background: The conventional fertilization regime ignores the allometric characteristics of Quercus nuttallii seedlings, challenging them to meet the nutritional needs at each growth stage. This study was conducted to determine the impact of exponential fertilization on the growth and nutrient status of Q. nuttallii container seedlings.

Abstract:
... Infrared radiation (IR) can effectively dry rice; however, the effects of IR on germination need to be determined. We compared the effects of natural air drying and three IR-drying intensities (2.15, 2.83, and 10.84 kW/m2) on rice germination for two rice cultivars, XL745 (hybrid) and CL152 (pureline). Although lower for CL152 than for XL745, the probability of germination was lowest after IR-dryi ...

Abstract:
... PURPOSE: Fine root decomposition plays an essential role in the nutrient cycle and energy transfer in terrestrial ecosystems, and changes in decomposition induced by nitrogen (N) deposition have become a global concern. However, patterns of fine root decomposition with N application are still scattered, and the dominant factors regulating decomposition are still controversial. Here, we aimed to ex ...

Abstract:
... Expansins play important roles in root growth and development, but investigation of the expansin gene family has not yet been reported in Ipomoea trifida, and little is known regarding storage root (SR) development. In this work, we identified a total of 37 expansins (ItrEXPs) in our previously reported SR-forming I. trifida strain Y22 genome, which included 23 ItrEXPAs, 4 ItrEXPBs, 2 ItrEXLAs and ...
... One of the longest standing theories and, therein-based, regulation-model of plant root development, posits the inhibitory action of auxin (IAA, indolylacetic acid) on elongation growth of root cells. This effect, as induced by exogenously supplied IAA, served as the foundation stone for root growth regulation. For decades, auxin ruled the day and only allowed hormonal side players to be somehow i ...
... In agronomy sciences and researches, root system architecture (RSA) of Oryza sativa L. (rice) is often used to reflect the spatial configuration of rice roots. But, because soil has its own opacity, the cognition and expression of the spatial morphology and structure of rice roots have become the bottleneck in the in-depth study. The three-dimensional (3D) modeling and visualization can be used to ...
