Rapid flooding-induced adventitious root development from preformed primordia in Solanum dulcamara
Flooding is a common stress factor in both natural and agricultural systems, and affects plant growth by the slow diffusion rate of gases in water. This results in low oxygen concentrations in submerged tissues, and hence in a decreased respiration rate. Understanding the responses of plants to flooding is essential for the management of wetland ecosystems, and may benefit research to improve t...
متن کاملLRP7, a Gene Expressed in Lateral and Adventitious Root Primordia of Arabidopsis
We describe a gene that is expressed in lateral and adventitious root primordia of Arabidopsis. The gene was identified by expression of a transposon-borne promoterless P-glucuronidase gene in lateral root primordia. The gene, designated LRP7 for lateral root primordium 1, and its corresponding cDNA were cloned and sequenced. The expression pattern of the gene in lateral root primordia was conf...
متن کاملLRP1, a gene expressed in lateral and adventitious root primordia of arabidopsis.
We describe a gene that is expressed in lateral and adventitious root primordia of Arabidopsis. The gene was identified by expression of a transposon-borne promoterless beta-glucuronidase gene in lateral root primordia. The gene, designated LRP1 for lateral root primordium 1, and its corresponding cDNA were cloned and sequenced. The expression pattern of the gene in lateral root primordia was c...
متن کاملMeristematic Activity during Adventitious Root Primordium Development: Influences of Endogenous Auxin and Applied Gibberellic Acid.
Intact brittle willows (Salix fragilis L.) were treated so that developing adventitious root primordia in the stems would be subjected to elevated gibberellic acid or reduced endogenous auxin levels. Observations were made of primordia that were initiated during the experiments and of primordia that were established before the experiments began. The results indicated that as primordia became ol...
متن کاملHypocotyl adventitious root organogenesis differs from lateral root development
Wound-induced adventitious root (AR) formation is a requirement for plant survival upon root damage inflicted by pathogen attack, but also during the regeneration of plant stem cuttings for clonal propagation of elite plant varieties. Yet, adventitious rooting also takes place without wounding. This happens for example in etiolated Arabidopsis thaliana hypocotyls, in which AR initiate upon de-e...
