Summary: The study reveals that NAA can promote the formation of AR in tea cuttings and has a synergistic effect with endogenous hormones. The level of the most important endogenous AR inductor, IAA, is reduced in response to NAA treatment. Comparative transcriptome analysis identifies DEGs potentially involved in NAA-mediated AR formation in tea stem cuttings. Weighted gene co-expression network analysis identifies several hub genes that may play important roles in AR formation in tea cuttings.

Summary: The study found that the use of IBA increased rooting of greenberry stem cuttings of R. brasiliensis, with rooting percentages less than 16% depending on the collection date. However, for root cuttings, the use of NAA and different diameters did not show positive results. Nevertheless, the combination of PBZ with IBA proved to be important for rooting of stem cuttings.

Summary: Cultivation of Baccharoides anthelmintica leaf explants on MS medium supplemented with 1 mg L-1 IBA led to the highest biomass of adventitious roots production. Treatment with methyl jasmonate and salicylic acid increased rhamnetin content in the roots of B. anthelmintica compared to untreated roots, showing potential for enhancing medicinal compound production.

Summary: Nothofagus antarctica, a main woody plant in temperate deciduous forests and anti-boreal forests of the southern hemisphere, has seen considerable reduction in its area due to fires caused by human activities. By using artificial regeneration and focusing on vegetative propagation to produce seedlings, efforts are being made to restore these forests. A trial showed success in rooting cuttings by optimizing collection period, substrate, and stimulator combinations, surpassing documented germination rates.

Summary: This review discusses multiple aspects of miRNAs' involvement in regulating root growth and development in plants. They play important roles in root elongation, lateral root formation, and adventitious root development, which are associated with hormone signaling, nutrient uptake, and biotic/abiotic stress. Additionally, the relationships between miRNAs and transcription factors, as well as target gene-mediated hormone signaling interactions, are crucial in the regulation of root growth and development.

Summary: The aim of this study was to assess the response of difficult-to-root and long-rooting stem cuttings to plant origin preparations. The results showed that the plant origin preparations could enhance rooting processes and improve the quality of cuttings. However, the effect of the plant origin preparations on the chlorophyll content in the leaves was inconclusive.

Summary: This experiment investigated the effect of various hormones on the rooting of rose cuttings and found that the content of polyphenolic acids decreased during the rooting process, but it did not clearly correlate with the rooting percentage or quality of the cuttings.

Summary: This study found that strigolactones have inhibitory effects on adventitious root formation in apple. Transcriptome analysis identified 12,051 differentially expressed genes related to adventitious root initiation. Further analysis indicated that strigolactones might inhibit root formation by repressing two core hub genes, MdLAC3 and MdORE1. Three negatively correlated miRNA-mRNA pairs were identified and validated. Overexpression of mdm-miR164b and silencing MdORE1 enhanced adventitious root formation in tobacco and apple, respectively. The role of mdm-miR164b-MdORE1 in strigolactone-mediated repression of rooting ability was confirmed. This comprehensive study provides insights into strigolactone-mediated adventitious root formation in woody plants and suggests a potential strategy for genetic improvement of rooting capacity.

Summary: This study analyzed the DNA methylome and transcriptome of adult and in vitro shoot culture-induced rejuvenation cuttings of apple rootstock M9T337. The results showed a global decrease in DNA methylation during rejuvenation, which may be correlated with changes in the expression of DNA demethylase and DNA methyltransferase genes. In addition, a DNA methylation inhibitor was found to enhance adventitious rooting ability and promote the expression of adventitious rooting-related genes in apple rootstock.

Summary: The Sustainable Sugarcane Initiative aims to increase disease-free sugarcane cultivation and improve yield globally. Single-bud seeds could be the best approach for sugarcane cultivation, and rooting agent Indole-3-butyric acid (IBA) significantly promotes growth in seedlings. The RNA sequencing analysis of sugarcane buds treated with IBA provided insight into gene expression during root development and revealed significant differentially expressed genes related to biological processes and molecular functions.

Summary: Root development in plants involves a complex interplay of growth, hormones, and signaling pathways, with auxin and the TOR pathway playing key roles in regulating root growth. Studying the crosstalk between auxin and TOR is crucial for understanding root morphogenesis, development, and architecture.
