Ribosomes, membranes and organelles during meiosis in angiosperms. by Dickinson, H, Heslop-Harrison, J

A MOLECULAR-BASIS FOR SELF-INCOMPATIBILITY IN ANGIOSPERMS by Dickinson, H

Small RNA pathways are present and functional in the angiosperm male gametophyte. by Grant-Downton, R, Hafidh, S, Twell, D, Dickinson, H

A radial system of microtubules extending between the nuclear envelope and the plasma membrane during early male haplophase in flowering plants. by Dickinson, H, Sheldon, J

“…The angiosperm male meiocyte is unusual among plant cells in that during early development ordered cellulosic microfibrils are not deposited at the protoplast surface. …”

The development of nuclear vacuoles during meiosis in plants. by Sheffield, E, Cawood, A, Bell, P, Dickinson, H

“…Vacuoles formed by the invagination of the inner membrane of the nuclear envelope have been observed during meiotic prophase in a wide range of plants. In the angiosperm Lycopersicon their formation was found to coincide with the completion of synaptonemal complex formation, and this timing is analogous to that observed during this stage in the silkworm Bombyx. …”

Origin of allelic diversity in antirrhinum S locus RNases. by Xue, Y, Carpenter, R, Dickinson, H, Coen, E

“…We propose that the recruitment of an ancestral RNase gene into SI occurred during an early stage of angiosperm evolution and that, since that time, new alleles subsequently have arisen at a low rate.…”

Bridging the generation gap: flowering plant gametophytes and animal germlines reveal unexpected similarities. by Dickinson, H, Grant-Downton, R

“…Nevertheless, a comparison between animal germlines and angiosperm gametophyte development reveals a number of surprising similarities at the cytological and molecular levels. …”

A novel extinction screen in Arabidopsis thaliana identifies mutant plants defective in early microsporangial development. by Sorensen, A, Guerineau, F, Canales-Holzeis, C, Dickinson, H, Scott, R

“…Analysis of these mutants has already raised questions about the accuracy of current models of angiosperm anther development.…”

DNA synthesis and cytoplasmic differentiation in tapetal cells of normal and cytoplasmically male sterile lines of Petunia hybrida. by Liu, X, Jones, K, Dickinson, H

“…These data are discussed in terms of the very special differentiation undergone by tapetal cells in angiosperms, and the conclusions drawn are considered in the perspective of current hypotheses proposed to explain the operation of CMS. …”

When genomes collide: aberrant seed development following maize interploidy crosses. by Pennington, P, Costa, L, Gutierrez-Marcos, J, Greenland, A, Dickinson, H

“… BACKGROUND AND AIMS: The results of wide- or interploidy crosses in angiosperms are unpredictable and often lead to seed abortion. …”

Imprinting in the endosperm: a possible role in preventing wide hybridization. by Gutierrez-Marcos, J, Pennington, P, Costa, L, Dickinson, H

“…In plants, these strategies involve either pre-zygotic barriers, such as differences in floral structure and pollen-stigma recognition, or post-zygotic barriers, which are less well understood and affect aspects of seed development ranging from fertilization to maturation. In most angiosperms, a double fertilization event gives rise to a zygote and the endosperm: a triploid tissue with an unequal parental genomic contribution, which, like the placenta of mammals, provides reserves to the developing embryo. …”
