Growth Adaptations to Water Stress Growing maize roots respond to mild water deficits by increasing the extensibility of cell walls in the apical growth zone, thereby permitting the roots to continue to grow. Mol Biol Evol 31: 376-386. Each voucher will expire in 30 days, if not used. Selaginella moellendorffii has a reduced and highly conserved expansin superfamily with genes more closely related to angiosperms than to bryophytes. Research Interests Mechanisms of Plant Cell Growth Cell expansion plays a crucial role in shaping the form and size of plants.

Grass Pollen Allergens as Beta-Expansins Group I allergens are the major allergens of grass pollen and cause seasonal asthma and related immune responses in many people. By use of transgenic plants with alterations in the expression of expansins, we plan to decipher the role of these proteins in cell enlargement, plant morphogenesis, and wall structure. A revised architecture of primary cell walls based on biomechanical changes induced by substrate-specific endoglucanases. Molecular dynamics simulation study of xyloglucan adsorption on cellulose surfaces: effects of surface hydrophobicity and side-chain variation. Changes in growth and cell wall extensibility of maize silks following pollination.
F1000 Reviews 5: 119-ff doi 10. Structure and Assembly of Plant Cell Walls To understand how plant cells grow enlarge , we need to know how the cell wall expands irreversibly and incorporates new structural materials into the cell wall to maintain its structural and mechanical integrity in the face of sustained expansion and thinning of the older wall layers. A group-1 grass pollen allergen influences the outcome of pollen competition in maize. Cosgrove has been a cast member during the series finale of three consecutive cancelled soap operas: Guiding Light, As the World Turns, and All My Children. He remained on Guiding Light until the show left the air on Sept.
Journal of Experimental Botany 61: 4097-4107. He later returned to the role in October 2007 and was nominated for his first for Outstanding Supporting Actor in a Drama Series in 2008. He is known for his roles as 3 on , on , on , on and for his role as on. Biochemical analysis of expansin-like proteins from microbes. Plant J 81 1 :108-20 doi:10.
Plant Journal 68: 546-559 Georgelis, N. Matrix solubilization and cell wall weakening by β-expansin group-1 allergen from maize pollen. Sexual Plant Reproduction 22: 141-152. Methods in Molecular Biology 715: 291-303. We'd be happy to assit you.
Other possible changes in wall structure are also being explored. Cosgrove returned to All My Children as Scott Chandler from December 2010 until the show's finale episode in September 2011. Journal of Biological Chemistry 286: 16814-16823. × A temporary password has been sent to. This activity is selective for grass cell walls and is, at least partly, due to the action of maize group I allergens.
We have found that expansins do not act by the conventional theory of wall loosening by polysaccharide hydrolysis; rather, they disrupt hydrogen bonding between wall polysaccharide in a unique way that might have commercial applications. Comparative structure and biomechanics of plant primary and secondary cell walls. That same year, Cosgrove moved to Los Angeles to take the role of on , where he remained until the show ended in 2000. Extracts of maize pollen possess potent expansin-like activity, as measured in wall extension and wall stress relaxation assays.
