Summary: The study identified the regulatory role of the MiR390/TAS3 pathway in lateral root development and nitrogen-fixing nodule formation; ARF3 and ARF4a are involved in lateral root development, while ARF4a also participates in nodule formation; The response of ARF2, ARF3, and ARF4a/b to rhizobia depends on the perception of Nod Factor.

Summary: The study found that when using splice grafting as a propagation strategy for watermelon, plants treated with sucrose and antitranspirant A had higher survival rates. Grafted plants with root-excised had lower survival rates compared to those with root-intact, while those treated with water had the lowest survival rates.

Summary: Studies have shown that ABA inhibits primary root elongation and lateral root density in maize, while auxin inhibits primary root elongation but increases lateral root density. The combined treatment of ABA and auxin can reverse the inhibitory effect of ABA on lateral root density. The inhibitory effect of ABA on lateral root primordia formation depends on the developmental stage.

Summary: This study investigated the effect of clubroot, a soilborne disease caused by Plasmodiophora brassicae, on plant hormones in Brassica napus. The results showed that the pathogen modulated plant hormonal networks, leading to increased levels of SA and ABA in susceptible plants, and decreased levels of JA. This modulation of plant hormones could be important for understanding plant defense mechanisms against clubroot.

Summary: Gravity plays a role in root system architecture, and the loss of function of the OsPIN2 gene in the rice wavy root 1 (war1) mutant leads to altered root architecture, disrupted auxin transport, decreased amyloplast sedimentation, and impaired ABA signaling. OsPIN2 not only regulates root gravitropism through auxin transport, but also affects seed germination and root development through ABA signaling.

Summary: The root system is crucial for the stable growth of plants. In this study, transcriptome sequencing and miRNA sequencing were used to investigate the gene expression and hormone content changes in grapevine roots under different cultivation conditions. The results revealed that root-restriction cultivation can regulate root development and hormone production.

Summary: In this study, a genome-wide analysis was conducted to investigate the ARF gene family in ginseng, leading to the discovery of 53 specific ARF genes in ginseng. These genes were found to be involved in the development of ginseng through the regulation of hormone-mediated genes. Additionally, segmental duplications played a significant role in the expansion of the ARF gene family in ginseng.

Summary: This study reveals the important role of auxin signaling in regulating the diameter of lateral roots in plants. The protein DRP is identified as a key factor in controlling lateral root diameter. The upregulation of auxin signaling in lateral root primordia promotes the expression of a positive regulator, OsWOX10, leading to an increase in lateral root diameter.

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 reveals the interplay between the calcium signaling module and auxin signaling in Arabidopsis, showing their important roles in callus and lateral root formation. The physical interaction between CaM-IQM and IAA proteins in a calcium-dependent manner is found to regulate auxin-induced callus formation.

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: Copper (Cu2+) is essential for plant growth but toxic in excess. AtNOA1 regulates Cu2+-induced lateral root (LR) formation by mediating LR elongation, affecting Cu2+ homeostasis and auxin redistribution.
