Systemic regulation of sulfur homeostasis in Medicago truncatula
Medicago Root morphology Split-root system Sulfur defiiency Sulfate transporters Systemic response
2015/2/5
Sulfur (S) is an essential macronutrient for plants, and defiiency in soil S availability limits plant growth. Adaptive strategies have been evolved by plants to respond to S defiiency by coordinating...
Medicago truncatula ecotypes A17 and R108 differed in their response to iron deficiency
Medicago truncatula Ecotype A17 Ecotype R108 Fe deficiency Ferric chelate reductase activity
2015/2/5
Medicago truncatula Gaertn is a model legume species with a wide genetic diversity. To evaluate the responses of the two M. truncatula ecotypes, the effect of Fe deficiency on ecotype A17 and ecotype ...
Elevated CO2 decreases the response of the ethylene signaling pathway in Medicago truncatula and increases the abundance of the pea aphid
Acyrthosiphon pisum (pea aphid) elevated CO2 ethylene Medicago truncatula nitrogen (N) metabolism resistance
2015/2/5
The performance of herbivorous insects is greatly affected by plant nutritional quality and resistance, which are likely to be altered by rising concentrations of atmospheric CO2.We previously repor...
A Medicago truncatula EF-Hand Family Gene, MtCaMP1, Is Involved in Drought and Salt Stress Tolerance
Medicago truncatula EF-Hand Family Gene MtCaMP1 Drought Salt Stress Tolerance
2015/2/5
Background: Calcium-binding proteins that contain EF-hand motifs have been reported to play important roles in transduction of signals associated with biotic and abiotic stresses. To functionally char...
Expression of a Medicago falcata small GTPase gene, MfARL1 enhanced tolerance to salt stress in Arabidopsis thaliana
MfARL1 Medicago falcata Arabidopsis thaliana Salt stress Small GTPases Na t accumulation
2015/2/5
To understand the role of small GTPases in response to abiotic stress, we isolated a gene encoding a small GTPase, designated MfARL1, from a subtracted cDNA library in Medicago falcata, a native legum...
A novel Medicago truncatula HD-Zip gene, MtHB2, is involved in abiotic stress responses
MtHB2 Abiotic stress Medicago truncatula Arabidopsis thaliana Pro Solublesugars Oxidative damage
2015/2/5
The HD-Zip proteins are important transcription factors participating in numerous physiological processes in plants. In this study, we identified a homeobox-leucine zipper gene from Medicago truncatul...
Ethylene-responsive miRNAs in roots of Medicago truncatula identified by high-throughput sequencing at whole genome level
Ethylene microRNA Medicago truncatula High-throughput sequencing
2015/2/5
Ethylene is one ofthe classical plant hormones with a diverse function in plant growth and development. Root elongation is sensitive to ethylene such that treatments with ethylene and the ethylene pre...
Identification of aluminum-responsive microRNAs in Medicago truncatula by genome-wide high-throughput sequencing
Aluminum toxicity High-throughput sequencing Medicago MicroRNA
2015/2/5
MicroRNAs (miRNAs) play important roles in response of plants to biotic and abiotic stresses. Aluminum (Al) toxicity is a major factor limiting plant growth in acidic soils. However, there has been li...
Identification of drought-responsive microRNAs in Medicago truncatula by genome-wide highthroughput sequencing
drought-responsive microRNAs Medicago truncatula genome-wide highthroughput sequencing
2015/2/5
Backg round: MicroRNAs (miRNAs) are small, endogenous RNAs that play important regulatory roles in development and stress response in plants by negatively affecting gene expression post-transcriptiona...
Comparative studies on tolerance of Medicago truncatula and Medicago falcata to freezing
Cold acclimation CRT binding factor (CBF) Medicago truncatula Medicago falcata Freezing tolerance Soluble sugars
2015/2/5
Medicago falcata is a legume species that exhibits great capacity of tolerance to abiotic stresses. To elucidate the mechanism underlying tolerance of M. Falcata to freezing, we compared the character...
Stimulation of root acid phosphatase by phosphorus deficiency is regulated by ethylene in Medicago falcata
Phosphorus deficiency Ethylene Medicago falcata Acid phosphatase activity Phosphate transporters Organic phosphorus
2015/2/5
Plants have developed numerous strategies to cope with phosphorus (P) deficiency resulting from low availability in soils. Evolution of ethylene and up-regulation of root secreted acid phosphatase act...
Phosphorus deficiency-induced reduction in root hydraulic conductivity in Medicago falcata is associated with ethylene production
Phosphorus deficiency Root hydraulic conductivity Ethylene production Aquaporins Medicago falcata L
2015/2/5
Plants grown in phosphorus-deficient solutions often exhibit disruption of water transport due to reduction in root hydraulic conductivity (Lpr) and enhanced ethylene production. To uncover the relati...
Correlations among Shearing Force, Morphological Characteristic, Chemical Composition, and In situ Digestibility of Alfalfa (Medicago sativa L) Stem
