Summary: Cytokinin and auxin are plant hormones that coordinate plant development. Their interactions in plant underground growth are well established. Different types of cytokinins have different effects on root growth, while some mutants show root phenotypes opposite to known cytokinin functions and related to auxin levels.

Summary: Auxin, one of the most widely studied phytohormones, has been a hot topic in plant biology. The advances in understanding auxin signaling, including perception, rapid responses, transcriptional and non-transcriptional branches, and epigenetic regulation, have been highlighted. Feedback inhibition mechanisms and non-canonical signaling have also been explored. Further identification of auxin signaling components and their regulation will deepen our understanding of how auxin signals regulate plant growth and development at the cellular level.

Summary: This study found that hydrogen sulfide (H2S) regulates salt tolerance and root growth in Arabidopsis through auxin signaling pathway. The results showed that H2S activates salt-related genes and limits growth-associated cellular activities through the regulation of auxin signaling. Moreover, H2S inhibits root growth by regulating the expression of PIN2 gene.

Summary: Fructokinase activates fructose through phosphorylation, but the overexpression of the apple FRK gene MdFRK2 leads to higher fructose levels in transgenic apple fruits. Further analysis reveals an MdCacyBP-MdFRK2 regulatory module that controls fructose homeostasis in different organs by ubiquitination and degradation of MdFRK2. This study provides useful insights into improving apple flavor and understanding plant fructose regulation.

Summary: The study found that McMYB4 is induced by high and low temperature treatments, leading to accumulation of flavonols and lignin in apple leaves, and regulating the expression of biosynthesis genes for these compounds. Additionally, McMYB4 can also accelerate the auxin and brassinolide signaling pathways, promoting plant growth and resistance to abiotic stress.

Summary: NAC transcription factor ClNAC68 plays a crucial role in fruit ripening and quality by repressing the expression of sucrose metabolism related genes and the IAA signaling pathway gene. Knockout of ClNAC68 leads to decreased soluble solid content and sucrose accumulation in fruit flesh, delayed development and inhibited germination in seeds, and reduced IAA content. These findings provide new insights into how NAC transcription factors affect fruit quality and seed development.

Summary: For most fruit and forest species propagated from elite genotypes, adventitious rooting is essential. The ability to form adventitious roots significantly decreases during the juvenile to adult phase change. In this study, it was shown that a correlation exists between MdWRKY87 expression level and adventitious rooting ability. Overexpression of MdWRKY87 in tobacco enhances adventitious rooting ability, increases the number of adventitious roots, and accelerates the adventitious rooting process.

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: Plant roots are able to adjust their tissue organization and cell appearance in response to abiotic stress. Previous studies have shown that sugar and light signaling can influence auxin biosynthesis and distribution in the root, which in turn affects almost all root traits. The availability of auxin is crucial for root hair emergence and elongation, which play a key role in nutrient uptake and plant productivity. Additionally, the study demonstrates how light and sugar can antagonistically influence root length but additively affect root hair emergence and elongation.

Summary: In this study, an ABA-responsive KNOX gene, MdKNOX19, was identified in apple. Overexpression of MdKNOX19 increased ABA sensitivity in apple calli and upregulated the transcription of the Arabidopsis ABI5-like gene MdABI5. MdKNOX19 was found to directly bind to the promoter of MdABI5, indicating a positive regulatory role in ABI5 expression and potentially contributing to organ development.

Summary: This study demonstrates that apple WUSCHEL2 (MdWUS2) is activated by cytokinin to inhibit the activity of MdTCP12, thereby regulating branching. MdTCP12 is a key factor in branching regulation, as its overexpression inhibits axillary bud outgrowth. Interaction experiments reveal that MdWUS2 interacts with MdTCP12 to suppress its transcriptional activation ability.

Summary: High nitrate concentration delays the development of adventitious roots in apple rootstocks, inhibiting their formation. This inhibition may be caused by hormonal imbalance within the plant body due to elevated levels of endogenous hormones in response to high nitrate. Genes related to nitrate, hormones, root development, and cell-cycle induction pathways were identified as potentially involved in regulating adventitious roots.

Summary: MdTFL1, a floral repressor in apple, forms complexes with multiple proteins and competes with MdFT1 in regulating reproductive development. MdTFL1 and MdFT1 exhibit similar interaction patterns, suggesting possible antagonistic roles in flowering regulation. The identification of hundreds of novel interaction proteins of MdTFL1 through yeast two-hybrid screens expands the floral regulatory network and introduces new roles for TFL1 in plant development.

Summary: miR393 is known to influence adventitious root formation in plants, and in this study, it was found to mediate AR formation in apple rootstock by targeted regulation of MdTIR1A expression. The evolutionary relationships of miR393 and TIR1/AFBs were systematically identified, and their expression patterns were analyzed, revealing significant changes during AR formation. The results suggest a conservative evolution of miR393 and provide insights into the molecular mechanisms underlying AR formation in apple rootstock.

Summary: Nitrate treatment at 28.1 mM/L was found to be the optimal concentration for adventitious root (AR) formation and development in B9 apple rootstocks. This study demonstrated that nitrate promotes AR formation by upregulating genes related to nitrate and auxin biosynthesis, ultimately leading to increased expression of AR development-related genes and cell cycle-related genes. The findings provide insights into the molecular mechanisms underlying nitrate-mediated AR formation in apple rootstocks.
