Phenolic cycle in plants and environment

Öz:

Fenolik maddeler bitkilerde ve toprakta sentezlenir. Bunlar polimerler ve monomerler şeklinde bulunurlar. Fenoliklerin monomer grubu bitki hücresinin kloroplastlarında biraraya gelirken, toprak fenolikleri toprak misellerinin alumino-silikat matriksi üzerinde humus oluşum olayı ile uyumluluk gösterir. Bitki büyürken hücre vakuollerinde fenolikler birikir veya sekonder hücre çeperlerine sağlamlık kazandıran ligninlere polimerize olurlar. Bunlara ilave olarak fenolikler hücre uzamasını düzenleyerek bazı fizyolojik işlevlere de sahiptirler. Bitki kök sistemlerinden salındıkları zaman hemen yakınındaki rizosferlerde büyümeyi inhibe edici etki meydana getirirler. Bu çalışma fenolik sentezlerinin en son deneysel verilerini ve çevredeki dönüşümlerini sunarken, bitki-toprak ilişkilerindeki etkilerini anlamamıza yardım etmektedir.

Phenolic substances are synthesized in plants and in the soil. They exist in the form of polymers and monomers. The latter group of phenolics is assembled within the chloroplasts of plant cells, whereas soil phenolics are associated with the process of humus formation on the alumino-silicate matrix of the soil micelle. As plants grow, phenolics accumulate in cell vacuoles, or polymerize into lignin, which strengthens the secondary cell walls. In addition to this, phenolics possess also some physiological functions as they regulate cell elongation. When they are excreted from plant root systems they exert inhibitory growth function within adjacent rhizospheres. This work presents the latest experimental evidence of phenolic synthesis and transformation in the environment, while providing an understanding of their effect in plant-soil relations.
