Summary: A study has found that theanine, synthesized by GSI-like proteins in tea plants, plays a crucial role in nitrogen signaling and development. Exogenous theanine inhibits lateral root development by reducing H2O2 accumulation. This study reveals the regulatory role of CsTSI-synthesized theanine in lateral root development in tea plants.

Summary: The rhizosphere is a soil-plant interface where bacterial and fungal species colonize and provide growth-promoting and adaptive benefits. Plant-bacteria relationships rely on the perception of volatile organic compounds (VOCs), phytohormones, and bacterial quorum sensing signals. Beneficial Trichoderma fungi emit active VOCs that contribute to plant morphogenesis and affect their colonization on roots. Recent findings have shed light on how compounds from beneficial bacteria and fungi impact root architecture and the signaling events mediating microbial recognition.

Summary: The study demonstrates that the inoculation of Paenibacillus lentimorbus B-30488 can promote plant growth under salinity and drought stress by modulating defense enzymes, phytohormones, and gene expression related to root system architecture. It is involved in altering root architecture, growth regulation, and enhancing plant growth in stress conditions.

Summary: Plant organogenesis requires the matching of metabolic resources with developmental programs. The root system in Arabidopsis is determined by primary root-derived lateral roots (LRs) and adventitious roots (ARs) formed from non-root organs. Lateral root formation requires the activation of transcription factors ARF7, ARF19, and LBD16. Adventitious root formation relies on the activation of LBD16 by auxin and WOX11. The allocation of shoot-derived sugar to the roots affects branching, but the mechanism of LRs formation is still unknown.

Summary: Roots are able to sense and respond to elevated temperature independently of shoot-derived signals. This response is mediated by an unknown root thermosensor that uses auxin as a messenger to relay temperature signals to the cell cycle. Growth promotion is primarily achieved by increasing cell division rates in the root apical meristem, dependent on de novo local auxin biosynthesis and temperature-sensitive organization of the polar auxin transport system.

Summary: The root system architecture of plants changes during salt stress exposure. Different accessions of Arabidopsis thaliana adopt different strategies in remodeling their root architecture during salt stress. Salt induces a multiphase growth response in roots, and both the growth rate of main roots during homoeostasis and lateral root appearance are the strongest determinants of overall root architecture. Furthermore, a trade-off between investing in main or lateral root length during salt stress is revealed. By studying natural variation in high-resolution temporal root growth using mathematical modeling, new insights in the interactions between dynamic root growth traits are discovered.

Summary: Research has shown that retinal binding occurs before lateral root formation and helps to promote root clock oscillations. The Arabidopsis protein TIL oscillates in the region of retinal binding, shares homology with vertebrate retinoid-binding proteins, and plays a role in lateral root organogenesis.

Summary: Microbes have an influence on the growth and adaptability of plants, but the microbiomes associated with rare and endemic plants have not been fully explored. This study investigated the bacterial community structure of an endemic plant in Korea and found that the root bacterial community structure differed from that of the soil and rhizosphere. The diversity of endogenous bacteria in cultivated plants was lower than in wild plants, but certain bacterial species were shared. The study also identified certain microbial strains that promoted growth and salt stress resistance in Arabidopsis and chive.

Summary: In Arabidopsis thaliana, the mutation in the GNOM gene severely inhibits lateral root (LR) formation, while the fewer roots suppressor1 (fsp1) mutation partially restores LR formation. It has been found that fsp1 mutation increases endogenous IAA levels and the number of sites where auxin response accumulates before LR formation, and SUR2 gene affects IAA accumulation in the pericycle cells at the xylem pole.

Summary: LR positioning and development are regulated by auxin production, transport, and inactivation. This study demonstrates the impact of GH3-type auxin conjugating enzymes and DAO1 in LR development. The gh3hex mutants exhibit increased LR density due to enhanced initiation and faster progression, with GH3 activities controlling LR formation. GH3-mediated auxin inactivation attenuates LR development by modulating meristem activities and apical meristem size, resulting in accelerated auxin response oscillations and increased LR initiation rates.

Summary: Leaf microbiota plays a crucial role in plant fitness and ecosystem functions. The composition of leaf microbiota is mainly determined by plant phenology and harsh environmental conditions. However, the impact of climate change on leaf microbiota remains unresolved, resulting in limited understanding of how environmental stresses associated with climate change affect the composition and functions of leaf microbes.

Summary: ABP1 is a key player in plant development with broad expression and possible involvement in additional auxin perception mechanisms. While it is not essential for transcriptional auxin signaling, gain-of-function alleles of ABP1 exhibit a wide range of growth and developmental defects.

Summary: The study found that exogenously applied ABA can suppress the formation of adventitious roots in Arabidopsis, while the synthetic ABA analog PB exhibits a stronger inhibitory effect. Additionally, analysis of various pyrabactin analogs suggests that adventitious root formation and lateral root branching are regulated differently by ABA signaling, with PYL1 and PYL2 identified as candidate ABA receptors that control AR inhibition.

Summary: Plant growth is regulated by environmental factors, such as how plants respond to gravity by bending shoots up and roots down. Research has shown that the plant hormone auxin affects root growth by regulating cell expansion and contraction in the roots.

Summary: This study reveals the molecular processes involved in the initiation of adventitious root (AR) formation along the hypocotyl of Arabidopsis seedlings exposed to light. The results show that AR induction by HYSPARIN involves nuclear TIR1/AFB and plasma membrane TMK auxin signaling, as well as multiple downstream LR development genes. Additionally, SAUR19, OFP4, and AGC2 are identified as novel regulators of AR formation.

Summary: This study reexamined the effects of auxin on PIN endocytic trafficking and found that high concentrations of NAA and IAA have nonspecific effects on the endomembrane system, while low concentrations specifically promoted endocytosis of PIN2. This contributes to polarity maintenance and highlights the nonspecific effects of high auxin levels on trafficking and endomembrane compartments.
