Effect of Ethylene on Root Architecture in Peas
نویسنده
چکیده
Root architecture describes root growth over time and space. Prior studies have examined the effects of ethylene and nutrient deficiency using ethylene precursors or inhibitors in combination with nutrient deficiency. To test if ethylene gas alone could alter root architecture in young pea plants, a 30 ppb flux of ethylene was maintained through a column root zone. Although not statistically significant, the data trend shows that roots grown without ethylene were longer, had more lateral branches, and supported larger shoots. This is contrary to literature that shows ethylene induces root growth under nutrient deficiency.

Effect of ethylene diamine tetra acetic acid chelator in the presence of chromium on growth and some physiological characteristics of sunflower.
Chromium is a heavy metal toxic for plants that due extensive industrial applications over the last decade, has become a serious environmental pollution. On the other hand, chelator dissolution and absorption of metal by the plant increase and their use in phytoremediation is important. The aim of this study was to evaluate the effect of different concentrations of chromium and ethylene diamine...
متن کاملDoes Iron Deficiency in Pisum sativum Enhance the Activity of the Root Plasmalemma Iron Transport Protein?
Roots of Fe-sufficient and Fe-Deficient pea (Pisum sativum L.) were studied to determine the effect of Fe-deficiency on the activity of the root-cell plasmalemma Fe(2+) transport protein. Rates of Fe(III) reduction and short-term Fe(2+) influx were sequentially determined in excised primary lateral roots using Fe(III)-ethylene-diaminetetraacetic acid (Fe[III]-EDTA). Since the extracellular Fe(2...
متن کاملPhosphate availability alters architecture and causes changes in hormone sensitivity in the Arabidopsis root system.
The postembryonic developmental program of the plant root system is plastic and allows changes in root architecture to adapt to environmental conditions such as water and nutrient availability. Among essential nutrients, phosphorus (P) often limits plant productivity because of its low mobility in soil. Therefore, the architecture of the root system may determine the capacity of the plant to ac...
متن کاملPyocyanin, a virulence factor produced by Pseudomonas aeruginosa, alters root development through reactive oxygen species and ethylene signaling in Arabidopsis.
Pyocyanin acts as a virulence factor in Pseudomonas aeruginosa, a plant and animal pathogen. In this study, we evaluated the effect of pyocyanin on growth and development of Arabidopsis seedlings. Root inoculation with P. aeruginosa PAO1 strain inhibited primary root growth in wild-type (WT) Arabidopsis seedlings. In contrast, single lasI- and double rhlI-/lasI- mutants of P. aeruginosa defecti...
متن کاملDetailed quantitative analysis of architectural traits of basal roots of young seedlings of bean in response to auxin and ethylene.
Vertical placement of roots within the soil determines their efficiency of acquisition of heterogeneous belowground resources. This study quantifies the architectural traits of seedling basal roots of bean (Phaseolus vulgaris), and shows that the distribution of root tips at different depths results from a combined effect of both basal root growth angle (BRGA) and root length. Based on emergenc...
