Drought is one of the major abiotic stresses limiting lentil productivity in rainfed production systems. Specific rooting patterns can be associated with drought avoidance mechanisms that can be used in lentil breeding programs. In all, 252 co-dominant and dominant markers were used for Quantitative Trait Loci (QTL) analysis on 132 lentil recombinant inbred lines based on greenhouse experiments...

This paper presents a new representation for root images based on Reeb graphs. The representation proposed captures lengths and distances in root structures as well as locations of branches, numbers of lateral roots and the locations of the root tips. An analysis of root images using Reeb graphs is presented and results are compared to ground truth measurements. This paper shows, that the Reeb ...

Acquisition of potassium (K) by roots plays the most important role in K efficiency of plants. However, limited information is available on morphological and physiological characteristics of roots in response to low-K stress. In this report, two tomato strains representing two distinct phenotypes of K-acquisition efficiency were studied using a sand±zeolite culture system. One was apparently mo...

Severe violet root rot occurred in a field of membranous milk vetch in Bonghwa, Korea, in October 2010. Two fungal isolates from the diseased plants were identified as Helicobasidium mompa based on their morphological, cultural, and molecular characteristics. This is the first report that H. mompa causes violet root rot on membranous milk vetch in Korea.

the response of root to water stress is one of the most important parameters for researchers. study of growth and distribution of root under different irrigation managements helpsresearchersto a better understanding of soil water content, and the availability of water and nutrition in water stress condition. to investigate the effects of four levels of irrigation under two different deficit irr...

BACKGROUND AND PURPOSE Image-guided selective nerve root block/steroid injection is commonly performed for lumbar radiculopathy. The purpose of this study was to evaluate the clinical/imaging characteristics and injection response of adjacent double-root contributions to unilateral lumbar radiculopathy in a typical interventional spine practice. MATERIALS AND METHODS In 132 of 350 patients (3...

Arbuscular mycorrhizal (AM) symbiosis can enhance plant resistance to NaCl stress in several ways. Two fundamental roles involve osmotic and ionic adjustment. By stimulating accumulation of solutes, the symbiosis can help plants sustain optimal water balance and diminish Na(+) toxicity. The size of the AM effect on osmolytes has varied widely and is unpredictable. We conducted a meta-analysis t...

Cation/proton antiporter 1 (CPA1) genes encode cellular Na+ /H+ exchanger proteins, which act to adjust ionic balance. Overexpression of CPA1s can improve plant performance under salt stress. However, the diversified roles of the CPA1 family and the various parameters used in evaluating transgenic plants over-expressing CPA1s make it challenging to assess the complex functions of CPA1s and thei...

The most common root malformations in humans arise from either developmental disorders of the root alone or disorders of radicular development as part of a general tooth dysplasia. The aim of this review is to relate the characteristics of these root malformations to potentially disrupted processes involved in radicular morphogenesis. Radicular morphogenesis proceeds under the control of Hertwi...
