With a very diverse structure and small molecules, phytohormones are regulators of plant growth development. Despite the fact that they synthesized by plants in quantities, highly active physiologically. According to their action, can be divided into two categories, as either activators development or inhibitors, with auxins cytokinins belonging former group. Auxins apical meristems shoots, but also young leaves, seeds, fruits. They stimulate elongation shoots initiate production adventitious lateral roots. Cytokinins, turn, formed root tips unripe fruits seeds. These hormones responsible for stimulating cytokinesis and, consequently, cell division. The aim this review paper is present progress research on effect selected crops, considering prospect using them growing methods.

Abstract The hemibiotrophic bacterial pathogen Pseudomonas syringae infects a range of plant species and causes enormous economic losses. Auxin WRKY transcription factors play crucial roles in responses to P. syringae, but their functional relationship immunity remains unclear. Here, we characterized tomato (Solanum lycopersicum) SlWRKY75, which promotes defenses against pv. (Pst) DC3000 by regulating auxin homeostasis. Overexpressing SlWRKY75 resulted low free indole-3-acetic acid (IAA) levels, leading attenuated signaling, decreased expansin transcript upregulated expression PATHOGENESIS-RELATED GENES (PRs) NONEXPRESSOR OF GENE 1 (NPR1), enhanced Pst DC3000.

Efficient adventitious root formation is essential in micropropagation. Auxin prodrugs, inactive precursors that convert into active auxins within the plant, offer potentially improved rooting control and reduced phytotoxicity. This study investigated efficacy of dichlorprop ester (DCPE), commercialized as Corasil® Clemensgros® (originally intended to increase grapefruit size), promoting vitro initiation model plant Populus × canadensis, compared its hydrolyzed form DCP related compound C77. DCPE displayed a stronger root-inducing effect than DCP, especially at lower concentrations (0.01 0.1 µM). Notably, 1 µM, both induced abundant aerial formation, phenomenon not previously observed poplar with traditional auxin treatments. Metabolite analysis revealed distinct patterns. treatment resulted rapid hydrolysis leading faster more systemic distribution throughout direct application. C77 treatments showed slower uptake limited translocation combined slow metabolism DCP. These results highlight potential prodrugs like an effective controllable source for optimizing protocols woody species.

Auxin is indispensable to the fertilization-induced coordinated development of embryo, endosperm, and seed coat. However, little attention has been given distribution pattern, maintenance mechanism, function auxin throughout process development. In present study, we found that response signals display a dynamic pattern during Arabidopsis Shortly after fertilization, strong were observed at funiculus, chalaza, micropylar integument where embryo attaches. Later, additional appeared middle layer inner (ii1') above chalaza whole outer (oi1). These peaked when was mature, then declined upon desiccation disappeared in dried seed. biosynthesis genes, including ASB1, TAA1, YUC1, YUC4, YUC8, YUC9, contributed accumulation funiculus efflux carrier PIN3 influx AUX1 also polar expressed ii1 (innermost integument) oi1 layers showed localization. both endosperm displayed uniform Further research demonstrated coat regulates size. Transgenic plants specifically express YUC8 gene oi2 or produced larger seeds. results provide useful tools for cultivating high-yielding crops.
