Abstract:
Plants, including most crops, are intolerant to waterlogging, a stressful condition that limits the oxygen available for roots, thereby inhibiting their growth and functionality. Whether root growth inhibition represents a preventive measure to save energy or is rather a consequence of reduced metabolic rates has yet to be elucidated. In the present study, we gathered evidence for hypoxic repression of root meristem regulators that leads to root growth inhibition. We also explored the contribution of the hormone jasmonic acid (JA) to this process in Arabidopsis thaliana. Analysis of transcript

Abstract:
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 defective in pyocyanin production showed decreased root growth inhibition concomitant with an increased phytostimulation. Treatment with pyocyanin modulates root system architecture, inhibiting primary root gro

Abstract:
The control of primary root growth in Zea mays cv. Merit by ethylene was examined. At applied concentrations of ethylene equal to or greater than 0.1 μL L−1, root elongation during 24 h was inhibited. The half-maximal response occurred at 0.6 μL L−1 and the response saturated at 6 μL L−1. Inhibition of elongation took place within 20 min. However, after ethylene was removed, elongation recovered to control values within 15 min. Root elongation was also inhibited by green light. The inhibition caused by a 24-h exposure to ethylene was restricted to the elongating region just behind the apex, wi

Abstract Boron (B) is an essential micronutrient for plant growth and development. Jasmonic acid (JA) plays pivotal roles in plant growth, but the underlying molecular mechanism of JA involvement in B-deficiency-induced root growth inhibition is yet to be explored. In this study, we investigated the response of JA to B deficiency and the mechanism of JAR1-dependent JA signaling in root growth inhibition under B deficiency in Arabidopsis. B deficiency enhanced JA signaling in roots, and root growth inhibition was partially restored by JA biosynthesis inhibition. The jar1-1 (jasmonate-resistant

Auxins play crucial regulatory roles in plants coping with cadmium (Cd) stress. However, the regulatory mechanism by which auxins alleviate Cd toxicity in tomato seedlings remains unclear. Here, we demonstrate that exposure to Cd stress leads to dynamic changes in the auxin response in tomato roots, characterized by an initial increase followed by a subsequent weakening. Under Cd stress, tomato seedlings show primary root- and hypocotyl-growth inhibition, accompanied by the accumulation of Cd and reactive oxygen species (ROS) in the roots.

The effects of L-canavanine, a structural analogue of L-arginine and a competitive inhibitor of arginine decarboxylase, were studied in corn (Zea mays L.) on primary root elongation and lateral root differentiation, meristematic activity, and on polyamine content and biosynthesis. Incubation of seedlings in 10−3 M L-canavanine for 3 h inhibited both elongation of the primary root and differentiation of lateral root primordia. A marked decrease in cell division and DNA synthesis, along with an inhibition of the activation of the primary root quiescent center, was clearly evident in L-canavanine

Abstract Presynaptic inhibition of primary afferents was proposed initially by Frank and Fuortes (1957) to account for the reduction of group la excitatory post synaptic potentials (EPSPs) in spinal motoneurons in the absence of detectable postsynaptic changes. Presynaptic inhibition was correlated with the dorsal root potential (DRP) and was thought to reflect the action of axoaxonal synapses (Eccles et al., 1961) that elicit depolarization of the primary afferent fibers (PAD) (Eccles et al., l 962a,b), but 26 years passed before PAD was recorded from functionally identified afferents Gimenez

Standard salinity management theory, derived from blending thermodynamic and semi- empirical considerations leads to an erroneous perception regarding compensative interaction among salinity stress factors. The current approach treats matric and osmotic components of soil water potential separately and then combines their effects to compute overall response. With deficit water a severe yield decrease is expected under high salinity, yet little or no reduction is predicted for excess irrigation, irrespective of salinity level.
