Male gametophyte specific expression helps identify a conserved gene associated with increased pollen fitness

Creator:: Colebrook, Sean Jr., Unger-Wallace, Erica, and Vollbrecht, Erik
Abstract:: GRMZM2G372877 was identified as a gene with potential function in the male gametophyte based on its strong expression in mature pollen relative to other maize tissues (Chettoor et al. 2014). Identification of a Ds insertion mutation in this gene from the Brutnell/Vollbrecht collection provided further support for this hypothesis, as...

Identification and characterization of seven ROP GTPases in Zea mays

Creator:: Christensen, Todd M.
Abstract:: Regulation of cell division and expansion are critical for plant development. The mechanisms that control these processes are not clearly understood in higher plants. In other eukaryotic models it has been shown that the highly conserved Rho family GTPases play a crucial role in these mechanisms. One distinct subset of...

Characterization of the transition to the progamic phase in Zea mays pollen

Creator:: Smyth, Johanna C.
Abstract:: The transition of mature pollen to the progamic phase represents an important step in the regulation of plant sexual reproduction. The progamic phase encompasses the initiation of pollen tube germination, growth of the pollen tube through the stigma (the silk in maize) and concludes with fertilization of the female gametophyte....

Seeing Genes: Multiscale Phenotyping Reveals Gene Functions in Maize Pollen

Creator:: Warman, Cedar D.
Abstract:: Plant sexual reproduction requires a broad array of molecular mechanisms to proceed successfully. Some of these mechanisms are well-studied, but our knowledge of them as a whole is fundamentally incomplete. Pollen tube growth is a key part of this process, facilitating the delivery of the sperm cells to the female...

Discovering the roles of myosin and exocyst proteins in cell expansion of Arabidopsis thaliana

Creator:: Goodrich, Danielle
Abstract:: The overall objective of this research was to determine which, if any, myosin XI proteins and exocyst proteins play a role in growth of Arabidopsis thaliana hypocotyls and root hairs. This involved the study of whether exocyst and myosin proteins work together during cell expansion within these two plant parts....

A NERD-Exocyst Interaction Facilitates the Growth of Roots and Root Hairs in Arabidopsis

Creator:: Moussaoui, Ibrahim
Abstract:: The growth of a plant’s root system is essential for its survival. Preliminary observations suggest that a protein complex called the exocyst may play a role in the development of the root system by facilitating the growth of roots and root hairs. Previous work discovered a protein that potentially interacts...

Toward a flexible and accurate approach to null network sampling

Creator:: Bright, Zachary A.
Abstract:: Null networks are a type of random graph that is favored for the analysis of a wide variety of real-world networks, including gene-regulatory networks, food webs, and species co-occurrence matrices. As a hypothesis-generating tool, null networks are invaluable because they can reveal network motifs and unusual large-scale properties of networks...

Responses and relationships among Fusarium species, sweet corn, and western spotted cucumber beetles

Creator:: Miller, Nathan L. (Nathan Louis)
Abstract:: Sweet corn (Zea mays L.) yields in the Willamette Valley of Oregon have been declining since the early 1990’s. Studies were done to determine if there is a relationship between ear weight and several disease parameters including necrotic crowns or stalk nodes, nodal root rot, radicle root rot, and sub-crown...

Generation of full-length cDNA clone and functional analysis of leader proteases of grapevine leafroll-associated virus-2

Creator:: Liu, Yu-Ping
Abstract:: Papain-like leader proteases are found in diverse families of human, animal, plant, and fungal positive-strand RNA viruses. In addition to autocatalytic processing, these proteases play a variety of roles in the virus life cycle. In particular, the leader protease (L-Pro) of a prototype member of the Closterovirus genus, Beet yellows...
