However to be considered as hormones, they have to respond to the translocatability criterion in the whole plant. The results presented here show that a small droplet (10 µl) of 14C-putrescine supplied to a source leaf is redistributed to the whole plant. Long-distance transport occurs mainly towards young growing organs (apex, roots, stolons, tubers). Bidirectional translocation, which is also found is a result of interactions between the attractive strengths of different sinks. Heat girdling of shoots induces a strong inhibition of transport which suggests transport via the phloem. Other data, such as non labeling of mature leaves, normally fed by xylem flux and the higher content (4 to 10 times) of endogenous PAs in phloem exudate compared with xylem exudate confirm this conclusion. After a 3 h period of transport, separation of labelled compounds by thin layer chromatography shows that the radioactivity supplied as 14C-putrescine is found as putrescine (from 64% to 82%), spermidine (from 14% to 28%) and spermine (3%) depending on the organ. This indicates that there is no important degradation of putrescine before it reaches the transport pathway.</div>","PeriodicalId":8798,"journal":{"name":"Biochemie und Physiologie der Pflanzen","volume":"188 3","pages":"Pages 169-176"},"PeriodicalIF":0.0,"publicationDate":"1992-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1016/S0015-3796(11)80004-1","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77549533","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Effects of Al on the cell Ca2+ homeostasis remain to be elucidated. Short-term net 45Ca2+ uptake by Amaranthus tricolor protoplasts was measured in media prepared to test the influence of various buffers, pH values, Ca2+ and Al concentrations. A modified GEOCHEM program was used to calculate activities of Ca2+ and all monomeric Al species. Net 45Ca2+ uptake was smaller at pH 4.5 compared to uptake at pH 5.5 and increased linearly with an increase in Ca2+ activity in the uptake media from 0.23 to 2.0 mM. Aluminium caused a significant decrease in net 45Ca2+ uptake. This Al-related decrease was less expressed at higher Ca2+ activities. Summed activities of monomeric Al species (Al3+ and hydroxy-Al) were significantly related to the reduction of net 45Ca2+ uptake. The equilibrium constant (Ki) of the reversible association of the Ca2+ membrane-transporter and monomeric Al species was calculated from Dixon plots to be equivalent to 4 and 30 micromolar activity of total monomeric Al for uptake media with pH values of 4.5 and 5.5, respectively. It is suggested that the primary Al effects are generally exerted through reducing inward Ca2+ fluxes across the plasma membrane.</div>","PeriodicalId":8798,"journal":{"name":"Biochemie und Physiologie der Pflanzen","volume":"188 3","pages":"Pages 177-186"},"PeriodicalIF":0.0,"publicationDate":"1992-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1016/S0015-3796(11)80005-3","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85196611","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
