In the native tobacco Nicotiana attenuata, NaRALF occurs as a single-copy gene and is highly expressed in roots and petioles. Silencing the NaRALF transcript by transforming N. attenuata with an inverted-repeat construct generated plants (irRALF) with normal wild-type (WT) above-ground parts, but with roots that grew longer and produced trichoblasts that developed into abnormal root hairs. Most trichoblasts produced a localized 'bulge' without commencing root hair tip growth; fewer trichoblasts grew, but were only 10% as long as those of WT plants. The root hair phenotype was associated with slowed apoplastic pH oscillations, increased pH at the tips of trichoblasts and decreased accumulation of reactive oxygen species in the root hair initiation zone. The root hair growth phenotype was partially restored when irRALF lines were grown in a low-pH-buffered medium, and reproduced in WT plants grown in a high-pH-buffered medium. When irRALF plants were grown in pH 5.6, 6.7 and 8.1 soils together with WT plants in glasshouse experiments, they were out-competed by WT plants in basic, but not acidic, soils. When WT and irRALF lines were planted into the basic soils of the native habitat of N. attenuata in the Great Basin Desert, irRALF plants had smaller leaves, shorter stalks, and produced fewer flowers and seed capsules than did WT plants. We conclude that NaRALF is required for regulating root hair extracellular pH, the transition from root hair initiation to tip growth and plant growth in basic soils. 000058481 536__ $$0G:(DE-Juel1)FUEK407$$2G:(DE-HGF)$$aTerrestrische Umwelt$$cP24$$x0 000058481 588__ $$aDataset connected to Web of Science, Pubmed 000058481 650_2 $$2MeSH$$aAmino Acid Sequence 000058481 650_2 $$2MeSH$$aCloning, Molecular 000058481 650_2 $$2MeSH$$aGene Silencing 000058481 650_2 $$2MeSH$$aHydrogen-Ion Concentration 000058481 650_2 $$2MeSH$$aMolecular Sequence Data 000058481 650_2 $$2MeSH$$aPhenotype 000058481 650_2 $$2MeSH$$aPlant Proteins: genetics 000058481 650_2 $$2MeSH$$aPlant Proteins: metabolism 000058481 650_2 $$2MeSH$$aPlant Proteins: physiology 000058481 650_2 $$2MeSH$$aPlant Roots: genetics 000058481 650_2 $$2MeSH$$aPlant Roots: growth & development 000058481 650_2 $$2MeSH$$aPlant Roots: metabolism 000058481 650_2 $$2MeSH$$aSequence Alignment 000058481 650_2 $$2MeSH$$aSoil 000058481 650_2 $$2MeSH$$aTobacco: genetics 000058481 650_2 $$2MeSH$$aTobacco: growth & development 000058481 650_2 $$2MeSH$$aTobacco: metabolism 000058481 650_7 $$00$$2NLM Chemicals$$aPlant Proteins 000058481 650_7 $$00$$2NLM Chemicals$$aSoil 000058481 650_7 $$2WoSType$$aJ 000058481 65320 $$2Author$$aNaRALF 000058481 65320 $$2Author$$aroot hair 000058481 65320 $$2Author$$atip growth 000058481 65320 $$2Author$$aextracellular pH oscillation 000058481 65320 $$2Author$$aplant fitness 000058481 65320 $$2Author$$aNicotiana attenuata 000058481 7001_ $$0P:(DE-HGF)0$$aKurten, E.L.$$b1 000058481 7001_ $$0P:(DE-HGF)0$$aMonshausen, G.$$b2 000058481 7001_ $$0P:(DE-Juel1)VDB67262$$aHummel, G.
