Identification and Characterization of Regulatory Pathways Controlling Dormancy Under Lower Temperature in Alfalfa ( L.).

Alfalfa ( L.), a kind of high-quality perennial legume forage, is widely distributed in the northern regions of China. In recent years, low temperatures have frequently occurred and limited alfalfa productivity and survival in early spring and late fall.

Identification and characterization of regulatory pathways involved in early flowering in the new leaves of alfalfa (Medicago sativa L.) by transcriptome analysis.

Background: Alfalfa (Medicago sativa L.) is a perennial legume extensively planted throughout the world as a high nutritive value livestock forage. Flowering time is an important agronomic trait that contributes to the production of alfalfa hay and seeds.

Cyclophilin AtROC1 confers Arabidopsis cold tolerance by modulating jasmonic acid signaling and antioxidant metabolism.

Cyclophilins (CYPs), a class of proteins with a conserved peptidyl-prolyl cis-trans isomerase domain, are widely involved in the regulation of plant growth and development, as well as in the response to abiotic stresses including cold. In our previous study, we identified an Arabidopsis gain-of-function mutant ROC1 with enhanced cold-tolerance and enhanced expression of jasmonic acid (JA) and oxidative stress responsive genes. Here, we show the underlying molecular mechanisms for the improved cold tolerance observed in the ROC1 mutant.

Sequence characteristics of Medicago truncatula cyclophilin family members and function analysis of MsCYP20-3B involved in axillary shoot development.

Cyclophilins (CYPs) belonging to the immunophilin family are present in all organisms and widely distributed in various cells associated with the activity of peptidyl-prolyl cis/trans isomerase. Plant CYPs are members of a multi-gene family and are involved in a series of biological processes. However, little is known about their structure, evolution, developmental expression and functional analysis in Medicago truncatula.
