Summary: The study revealed that lateral roots play a crucial role in the uptake of high manganese and cadmium in rice, while root hairs have less impact. Mutants with defective lateral roots showed significantly lower uptake of manganese and cadmium, confirming the essential role of lateral roots in this process.

Summary: Roots reinforce soil by acting as soil pins, dissipating shear stresses and anchoring the soil in place. The presence of root hairs appears to have a positive impact on the ability of roots to reinforce soil.

Summary: The symbiotic relationship between plants and fungi undergoes changes across an urban gradient, with plant communities playing a crucial role in arbuscular mycorrhizal fungal colonization levels. However, non-mycorrhizal fungal colonization increases with urbanization. Additionally, root hair presence increases with urbanization. These patterns are driven by an urban syndrome rather than soil chemistry.

Summary: This study investigated the root responses and physiological consequences of maize under boron deficiency. The results showed that maize plants did not inhibit root growth or show compensatory root foraging behavior under boron-deficient conditions. This atypical response provides important information for understanding the root responses of maize to boron deficiency.

Summary: Soil drying is a limiting factor for global crop production, but the impact of water uptake across different soils, species, and root phenotypes is not well understood. This study proposes a hydraulic framework to investigate how soil and root hydraulic properties interact in water uptake. The findings show that soil drying leads to a rapid decrease in soil hydraulic conductance, and root phenotypes with low root hydraulic conductance, long roots, and/or long and dense root hairs can postpone soil limitation. This has important implications for crop water use efficiency.

Summary: Root length distributions are commonly used to approximate root water uptake profiles, assuming a constant water uptake rate per unit root length. However, our study found significantly greater water uptake rates per unit length in shallower roots compared to deeper roots, challenging this assumption.

Summary: The MEDIATOR complex plays important roles in root biology, including root architecture, hormonal responses, nutrient stress adaptation, and meristem cell survival. Changes in the subunits and accessory histone acetyltransferases of MEDIATOR may affect gene expression. MEDIATOR interacts with TOPLESS and is involved in auxin and jasmonic acid responses, affecting the binding of transcriptional regulators to gene promoters. It also plays a crucial role in nutrient stress adaptation and plant productivity.

Summary: In this paper, a multiscale analysis of nutrient uptake by plant roots is conducted by considering the scale relations between the radius of root hairs and the distance between them. The method of formal asymptotic expansions is combined with rigorous derivation of macroscopic equations to study a distinguished limit and determine higher-order correctors. The results of the asymptotic analysis are validated through direct comparison with full-geometry numerical simulations.

Summary: The study found that root response to heterogeneous nutrient patches not only leads to root proliferation, but also accompanies root hair elongation. Genotypes without root hairs increased investment in lateral roots in nutrient-rich patches to compensate for the absence of root hairs, enhancing nutrient acquisition through regulating the trade-off of complementary root traits.

Summary: This paper investigates the variations in root systems and plasticity of two sorghum genotypes in response to different P concentrations. The two genotypes showed similar characteristics for most traits measured, but the red genotype had significantly longer total and lateral root lengths. The responses and plasticity of the root traits to P supply were more prominent at the five-leaf stage compared to the GPD stage.

Summary: This study aimed to clarify the role of nitric oxide (NO) in the regulation of vacuolar H+-ATPase (V-ATPase) in cucumber seedlings' roots under control and Cd stress conditions. The study also verified the relationships between NO and salicylic acid (SA), hydrogen sulfide (H2S), and hydrogen peroxide (H2O2). The results indicate that NO functions as a positive regulator of V-ATPase, and its regulation depends on NO generated by nitrate reductase and NOS-like activity. In cucumber roots, NO signaling interacts with the SA pathway and, to a lesser extent, with H2O2 and H2S.

Summary: Three plant rhizogenic strains O132T, O115 and O34 isolated from Cucumis sp. L. are classified as a novel species, Agrobacterium cucumeris, based on their genetic sequences, DNA-DNA hybridization, and physiological characteristics compared with their closest relatives in the genus Agrobacterium. These strains belong to the separate sub-clade biovar 1 within the genus Agrobacterium.

Summary: Rice root system primarily absorbs phosphate through nodal roots, while thinner S-type roots and root hairs play significant roles in phosphate uptake; however, producing nodal roots requires a large investment of phosphate and has a long pay-off time, which could be a burden for P-starved plants, suggesting the need to find more efficient strategies for optimizing root system architecture in overcoming phosphate deficiency.

Summary: The study reveals that ectopic expression of peptides IMA1 and IMA2 improves plant growth on calcareous soil by enhancing iron uptake, which is mediated by the biosynthesis and secretion of the compound fraxetin. This response is dependent on elevated environmental pH and involves the regulation of gene expression to adapt to different soil conditions.

Summary: AL6 plays a critical role in cellular phosphate homeostasis and root hair elongation, as well as in the response of Arabidopsis seedlings to jasmonic acid during skotomorphogenesis by modulating chromatin dynamics. Comparison of protein profiles between wild-type and al6 mutant seedlings using a modified Chromatin Enrichment for Proteomics approach highlighted the role of AL6 in chromatin organization and deposition of histone variants in response to internal or environmental stimuli.

Summary: In concert with oxygen, soil alkalinity strongly restricts the availability of iron, an essential nutrient with a multitude of functions in living organisms. This versatile, reciprocal plant-microbiome interplay affects iron mobilization directly, but also collaterally by impacting growth, fitness, and health of the host.

Summary: Iron is an essential element for all forms of life, including plants, and its homeostasis is crucial for cellular processes. This study investigated the mechanisms of systemic iron transport mediated by OPT3, activation of IMA genes in the phloem, and iron uptake in the root epidermis. The results revealed potential regulators of cellular iron homeostasis and identified plastid-encoded loci that may be involved in retrograde control of root iron uptake.
