    Studysummary This study found that the peach gene CTG134 mediates auxin-ethylene crosstalk, affecting root hair growth and hormone-regulated processes in plants. Our plain-language summary of this paper — not a Tressless recommendation.
    The study investigated the role of the peach RGF/GLV signaling peptide pCTG134 in regulating auxin and ethylene actions during fruit ripening. Researchers found that pCTG134 was involved in a feedback loop that sustained the levels and activities of these two hormones, crucial for plant growth and development. Overexpression of CTG134 in Arabidopsis and tobacco led to altered root development and larger fruit size, indicating its significant role in auxin-ethylene crosstalk. The findings suggested potential applications in designing new agrochemicals for fruit quality control.
