    MMP-2 Is Mainly Expressed in Arterioles and Contributes to Cerebral Vascular Remodeling Associated with TGF-β1 Signaling

    There is increasing evidence to suggest that matrix metalloproteinases (MMPs) play a crucial role in vascular remodeling. It has been reported that hypoxia stimulated MMP-9 expression in brain endothelial cell...

    Improved somatic embryo maturation in loblolly pine by monitoring ABA-responsive gene expression

    During loblolly pine zygotic embryo development, increases in mRNAs for three ABA-responsive LEA-like genes coincided with the two developmental stage-specific peaks of endogenous ABA accumulation (Kapik et al. 1...

    Rapid and Reliable Differential Display from Minute Amounts of Tissue: Mass Cloning and Characterization of Differentially Expressed Genes from Loblolly Pine Embryos

    Performing RNA differential display analysis on small tissue samples is difficult since much RNA, the initial template for the reaction, is lost during conventional isolation procedures. We have developed a ra...

    Embryos of alfalfa (Medicago sativa L.) can synthesize storage proteins after the completion of germination, in response to abscisic acid and osmoticum, if maturation drying is prevented

    The major 2S, 7S and 11S storage proteins are synthesized at the midto late stages during development of alfalfa seeds, mainly within the embryos. Mature dry seeds cannot synthesize these proteins upon subsequ...

    Contrasting pattern of somatic and zygotic embryo development in alfalfa (Medicago sativa L.) as revealed by scanning electron microscopy

    Scanning electron microscopy has been used to investigate the morphological changes occurring during the development of alfalfa somatic embryos. Embryos were initiated from callus, transferred to suspension cu...

    Abscisic acid and osmoticum prevent germination of develo** alfalfa embryos, but only osmoticum maintains the synthesis of developmental proteins

    Develo** seeds of alfalfa (Medicago sativa L.) acquire the ability to germinate during the latter stages of development, the maturation drying phase. Isolated embryos placed on Murashige and Skoog medium germin...
