Summary: Tomato trichomes serve as mechanical and chemical barriers against herbivores, and auxin treatment can increase the formation of specific types of trichomes on tomato leaves. Genes SlARF4, SlTHM1, and SlMYB52 play crucial roles in regulating trichome formation and providing tolerance to spider mites in tomato plants. The interplay between these genes and cyclin gene SlCycB2 modulates the formation of trichomes in tomato leaves through the R2R3 MYB-dependent auxin signaling pathway.

Summary: The trichomes of rice leaves are formed by the differentiation and development of epidermal cells. Plant trichomes play a crucial role in stress resistance and protection against direct ultraviolet irradiation. This study identified and characterized a mutant, lhl1 (less hairy leaf 1), which exhibited defective trichome development in rice leaves. The gene responsible for this phenotype, LOC_Os02g25230, was identified and its role in trichome development was verified through RNA interference and overexpression experiments.

Summary: This study investigated the changes in gene expression profiles and gene regulatory networks after topping tobacco plants. The results showed that core elements of K+ uptake and xylem loading were dramatically suppressed in roots after topping. It was also found that changes in auxin content could affect K+ uptake by influencing the activity of K+ uptake-related genes through the tobacco auxin response factor (NtARF) genes, resulting in changes in K+ content. These findings are important for enhancing K+ uptake and improving leaf quality in tobacco breeding.

Summary: Magnesium deficiency is becoming a limiting factor for crop production, affecting the total Mg2+ content in plants. The up-regulation of magnesium transporters in response to Mg deficiency was found to lead to a smaller root system in tomato seedlings. Additionally, a decrease in auxin concentrations and overall down-regulation of genes in the auxin signaling pathway were observed under Mg limitation.

Summary: The SIMYB75 gene plays a crucial role in tomato trichomes, with down-regulation increasing trichome formation and tolerance to spider mites, while overexpression inhibits these processes. The perturbation of SIMYB75 affects multiple transcriptional circuits, resulting in changes in trichome density and metabolic content.

Summary: The study characterized the formation of adventitious roots in tomato seedlings after whole root excision using physiological, genetic, and molecular approaches. It was found that regulated auxin transport and biosynthesis are crucial for re-establishing internal auxin gradients, leading to cell proliferation and the formation of new adventitious roots at specific positions.

Summary: Research has shown that tomato plants exhibit genotype-specific symptoms progression upon TSWV infection. The regulation of miRNA167a and ARF8 gene by TSWV disrupts plant growth intentionally to promote spread in sensitive cultivars, affecting auxin synthesis and shaping tomato responses to the virus. Modulation of the miR167a-ARF8 regulatory module could potentially be utilized in tomato resistance breeding programs.

Summary: ARF4 regulates shoot regeneration by competing with ARF5 for the interaction with IAA12. Enhanced expression of IAA12 compromises shoot regeneration capacity. The study reveals that ARF4 cooperates with ARF5 and IAA12 to modulate shoot regeneration.

Summary: This study identified a novel transcription factor, Lanata (Ln), which regulates multicellular trichome formation in tomato. Ln interacts with trichome regulators Woolly (Wo) and Hair (H), and through the regulation of SlCycB2 and SlCycB3 expression, it affects trichome density. Additionally, there is a mutual repression between SlCycB2 and SlCycB3.

Summary: The spatial patterns of prickles on rose stems are controlled by inhibitor diffusion, primarily emerging at specific angles from the spiral arrangement of leaf primordia. A simple mathematical model was proposed to explain the spatial patterns, which was validated in other plant species. This study provides new insights into prickle development and the possibility of applying similar systems to understand other plant species.

Summary: This study identifies the negative regulator MdARF5-1 in apple as a component of the auxin signaling pathway that inhibits anthocyanin biosynthesis by suppressing the expression of the ethylene response factor MdERF3. The auxin repressor MdIAA29 attenuates the inhibitory effect of MdARF5-1 on anthocyanin biosynthesis by alleviating the transcriptional inhibition of MdERF3. Furthermore, the E3 ubiquitin ligases MdSINA4 and MdSINA11 regulate anthocyanin biosynthesis by targeting MdIAA29 and MdARF5-1 for ubiquitination degradation, respectively.

Summary: Auxin, an important phytohormone in plant, negatively regulates chlorophyll biosynthesis by suppressing the expression of chlorophyll biosynthesis genes such as PORA and GUN5 with the help of IAA14. The yuc2 yuc6 double mutant showed higher chlorophyll content and improved photosynthetic efficiency, indicating the inhibitory role of auxin in chlorophyll metabolism. Our findings provide new insights into the interplay between auxin signaling and chlorophyll metabolism.

Summary: This study identified the RcMYB106 transcription factor as a key regulator of capsule spine development in castor through genetic analysis. It was found that a deletion or a single nucleotide polymorphism in the RcMYB106 gene led to the spineless capsule phenotype. The study also proposed a potential regulatory mechanism involving the downstream gene RcWIN1, but further experimentation is needed.

Summary: This study found that treatment with ethylene and brassinosteroid can promote the ripening of tomatoes, while treatment with auxin and gibberellin can delay ripening. Cold storage can delay the ripening process of tomatoes. These findings provide an important understanding of the complex hormone interactions regulating the postharvest physiology of tomatoes and contribute to maintaining their quality and shelf life.
