2025年1月23日 · To date, more than 30 families of putative peptide hormones have been identified in various plant species, such as CLAVATA3 (CLV3)/EMBRYO SURROUNDING REGION-RELATED peptides (CLEs), C-TERMINALLY ENCODED PEPTIDES (CEPs), PHYTOSULFOKINES (PSKs), EPIDERMAL PATTERNING FACTORS (EPFs), and RAPID ALKALINIZATION FACTORS (RALFs).

2024年2月14日 · The biosynthetic dogma of ribosomally synthesized and posttranslationally modified peptides (RiPP) involves enzymatic intermolecular modification of core peptide motifs in precursor...

2023年12月4日 · We identified subtilases necessary and sufficient to process PROSCOOP peptides at conserved cleavage motifs. Mutation of these subtilases, or their recognition motifs, suppressed PROSCOOP...

2016年5月27日 · Peptide-receptor matching is important for understanding the mechanisms underlying peptide-mediated signaling. Here we report the structure-guided identification of root meristem growth factor...

2019年9月16日 · Plants sense different parts of the sun's light spectrum using distinct photoreceptors, which signal through the E3 ubiquitin ligase COP1. Here, we analyze why many COP1-interacting transcription factors and photoreceptors harbor sequence-divergent Val-Pro (VP) motifs that bind COP1 with different binding affinities.

2016年11月7日 · Secreted signaling peptides or peptide hormones play crucial roles in plant growth and development through coordination of cell–cell communication. Perception of peptide hormones in plants generally relies on membrane-localized receptor kinases (RKs).

Peptides fulfill a plethora of functions in plant growth, development, and stress responses. They act as key components of cell-to-cell communication, interfere with signaling and response pathways, or display antimicrobial activity. Strikingly, both the diversity and amount of plant peptides have been largely underestimated.

2019年7月27日 · Plants sense different parts of the sun's light spectrum using distinct photoreceptors, which signal through the E3 ubiquitin ligase COP1. Here, we analyze why many COP1‐interacting transcription factors and photoreceptors harbor sequence‐divergent Val‐Pro (VP) motifs that bind COP1 with different binding affinities.

Background: Plant peptide hormones play a crucial role in plant growth and development. A group of these peptide hormones are signaling peptides with 5 - 23 amino acids. Flagellin peptide (flg22) also elicits an immune response in plants. The functions are expressed through recognition of the peptide hormones and flg22.

2017年8月14日 · Cysteine-rich peptides (CRPs) are a group of proteins that mediate many aspects of plant physiology and development. These proteins have emerged as plant peptide ligands that trigger membrane receptors to induce plant growth, plant defence, plant–bacteria symbiosis and plant reproduction [1, 2].
