Our study constructed a protein atlas of 12,702 glyoxysome proteins. To our knowledge, this is the deepest proteome of any plant organelle. By comparing the abundance of proteins found in the glyoxysome and in the control tissue, enrichment values for each protein were calculated. Aphids are small sap-sucking insects and members of the superfamily Aphidoidea. Aphid on leaf05.jpg. Aphids are among the most destructive insect pests on cultivated plants in.

Biology Harvard University, 1975 B.S. Botany University of California, Davis, 1967 The Feldman Lab broadly researches plant development, with an emphasis on roots and the root meristem, including the root cap. We have focused much of our work on a population of cells known as the quiescent center and have shown that many of its activities and characteristics are related to redox status.
For this effort we have developed a redox-sensing GFP which allows us to measure, in real time, redox status. We hypothesize that many of the profound effects and controls of auxin on root development are associated with changes in redox status. We also use microarrays to characterize distinct root meristem populations, including the root cap, in which we study gravity signal transduction. A major goal of all of our work is to link molecular changes with biochemistry.
A second major emphasis involves developing biosensors to allow plants to act as reporters of their own physiological status. We have focused on the development of biosensors for heat stress. Our long term goal is to improve crop yield by having the plant 'tell' us when it needs some alteration of its growing conditions (for example, cooler temperatures, or water), before it experiences stress, and thus reduction in yield. Regulation of development in meristems/stem cells; Root gravitropism; redox regulation of plant development.
Our lab's interests are in the area of plant development, with an emphasis on meristems, particularly those of roots. Download lagu soundtrack transformer dark of the moon. Dust hakida referat. We are investigating how the various populations of cells which comprise or surround the meristem interact to control root development, especially patterning. Much of our recent effort has focused on two populations of cells: the root cap, and a region of mitotically inactive cells known as the quiescent center. We have shown that quiescent center formation precedes the organization of a root meristem and have hypothesized that a quiescent center is necessary for meristem organization.
