The C-Terminal Motif Of Siago1b Is Required For The Regulation Of Growth, Development And Stress Responses In Foxtail Millet (Setaria Italica (L.) P. Beauv), Xiaotong Liu, Sha Tang, Guanqing Jia, James C. Schnable, Haixia Su, Chanjuan Tang, Hui Zhi, Xianmin Diao
The C-Terminal Motif Of Siago1b Is Required For The Regulation Of Growth, Development And Stress Responses In Foxtail Millet (Setaria Italica (L.) P. Beauv), Xiaotong Liu, Sha Tang, Guanqing Jia, James C. Schnable, Haixia Su, Chanjuan Tang, Hui Zhi, Xianmin Diao
Department of Agronomy and Horticulture: Faculty Publications
Foxtail millet (Setaria italica (L.) P. Beauv), which belongs to the Panicoideae tribe of the Poaceae, is an important grain crop widely grown in Northern China and India. It is currently developing into a novel model species for functional genomics of the Panicoideae as a result of its fully available reference genome sequence, small diploid genome (2n=18, ~510 Mb), short life cycle, small stature and prolific seed production. Argonaute 1 (AGO1), belonging to the argonaute (AGO) protein family, recruits small RNAs and regulates plant growth and development. Here, we characterized an AGO1 mutant (siago1b) in foxtail millet, which …
The Involvement Of J-Protein Atdjc17 In Root Development In Arabidopsis, Carloalberto Petti, Meera Nair, Seth Debolt
The Involvement Of J-Protein Atdjc17 In Root Development In Arabidopsis, Carloalberto Petti, Meera Nair, Seth Debolt
Horticulture Faculty Publications
In a screen for root hair morphogenesis mutants in Arabidopsis thaliana L. we identified a T-DNA insertion within a type III J-protein AtDjC17 caused altered root hair development and reduced hair length. Root hairs were observed to develop from trichoblast and atrichoblast cell files in both Atdjc17 and 35S::AtDJC17. Localization of gene expression in the root using transgenic plants expressing proAtDjC17::GUS revealed constitutive expression in stele cells. No AtDJC17 expression was observed in epidermal, endodermal, or cortical layers. To explore the contrast between gene expression in the stele and epidermal phenotype, hand cut transverse sections of Atdjc17 roots were …
Life History Of Paracoccus Marginatus (Hemiptera: Pseudococcidae) On Four Host Plant Species Under Laboratory Conditions, Kaushalya G. Amarasekare, Catharine M. Mannion, Lance S. Osborne, Nancy D. Epsky
Life History Of Paracoccus Marginatus (Hemiptera: Pseudococcidae) On Four Host Plant Species Under Laboratory Conditions, Kaushalya G. Amarasekare, Catharine M. Mannion, Lance S. Osborne, Nancy D. Epsky
Agricultural and Environmental Sciences Faculty Research
Life history of the mealybug, Paracoccus marginatus Williams and Granara de Willink, on three ornamental plants [Hibiscus rosa-sinensis L., Acalypha wilkesiana (Muell.-Arg.), and Plumeria rubra L.] and one weed species (Parthenium hysterophorus L.) was studied under laboratory conditions. Mealybugs were able to develop, survive, and reproduce on all four hosts; however, there were differences in the life history parameters. Adult females that developed on acalypha and parthenium emerged ≈1 d earlier than those that developed on hibiscus and plumeria. Adult males had a longer developmental time on plumeria than on the other hosts. Survival of first- and second-instar …
Life History Of An Exotic Soft Scale Insect Phalacrococcus Howertoni (Hemiptera: Coccidae) Found In Florida, Kaushalya G. Amarasekare, Catharine M. Mannion
Life History Of An Exotic Soft Scale Insect Phalacrococcus Howertoni (Hemiptera: Coccidae) Found In Florida, Kaushalya G. Amarasekare, Catharine M. Mannion
Agricultural and Environmental Sciences Faculty Research
We investigated the life history of an exotic soft scale insect, Phalacrococcus howertoni Hodges and Hodgson that damages croton and several other economically important ornamental and fruit plants in Florida. There was no difference in the development, survival, and reproduction of this scale insect species when reared either on croton or on buttonwood at 27 ± 1°C, 12:12 (L:D) h and 65% R. H. The scale insect practiced ovoviviparity. We observed that eggs that came out from vulva hatched to first instars immediately. Newly hatched nymphs had a tendency stay underneath the female body for somewhat less than approximately 24 …
The Effect Of A Controlled Nitrogen Supply With Different Temperatures And Photoperiods Upon The Development Of The Potato Plant, H. O. Werner
Historical Research Bulletins of the Nebraska Agricultural Experiment Station
The potato (Solanum tuberosum Linn.) is grown under a great variety of conditions with regard to temperature, length of day, intensity and character of light, texture, fertility, and moisture of soil, and atmospheric humidity. There is need for a better understanding concerning the internal response of the potato plant to these external conditions when they are applied, either singly or in combination with each other, and the resulting morphological response, especially with regard to the tuberization process. It has been the object of this investigation to determine the relation of the nitrogen supply to the processes of stolon and …
