From microbiome diversity to endophyte ecology in the wild grass Agrostis capillaris
The plant microbiome has been of particular interest in recent decades, as it plays a crucial role in the survival of its host. The large diversity of microorganisms that compose the plant microbiome, as well as the numerous factors that influence them, makes it difficult to understand the …

Genomics and regulatory functions of microRNAs and small silencing RNAs in Arabidopsis thaliana
… in critical developmental transitions. In plants, endogenous small RNAs consist of two broad classes, the ~21-nucleotide (nt) microRNAs (miRNAs) and the diverse ~22-24-nt trans-acting and heterochromatic short interfering RNAs (siRNAs). In order to more extensively characterize the small …

A Catharanthus roseus mutant with trace levels of secologanin and monoterpenoid indole alkaloids does not express BIS1/BIS2 transcription factors and fails to activate iridoid biosynthesis.
… or translocation of MIAs or pre-MIAs between organs within Catharanthus roseus has not been studied. Previously, 3600 EMS (ethyl methane sulfonate) mutagenized C. roseus plants had been screened with a simple TLC (thin layer chromatography) to identify mutants with altered MIA profiles yielded …

Heavy metal phytotoxicity: the effects of lead on the common reed, Phragmites australis (Cav.) Trin. ex Steud.
… (Cav.) Trin. ex Steud (common reed) as increased plant productivity is thought to be integral to the metal removal process. Hydroponic gravel-based mesocosms planted with vegetative reed propagules were regularly dosed with 50 μM Pb at pH 4 during 1996-7. Sequential plant harvesting over two …

An Integrative Analysis of Fruit Shape in Capsella rubella and Arabidopsis thaliana
Plant organs develop from a small number of cells into a wide variety of shapes. This development is coordinated by underlying genetic factors that control the organisation and patterning of growth. The Arabidopsis fruit has been studied in detail and genes involved in fruit shape development and …

Investigating the role of DA1 in growth control.
… A detailed understanding of the growth of plant organs in general is paramount if such advances are to be made. Utilising previously characterised regulators of plant organ growth, this thesis explores the molecular mechanisms involved in the setting of final organ size. This thesis …

Effects of cultivar, leaf position, and stem tissue on growth of single-leaf cuttings of Ipomoea Batatas Lam
… ‘Centennial,’ ‘Jewel,’ and ‘Nemagold’ were planted in plastic pots containing steam-sterilized sand. Fully opened leaves were counted from the terminal apex on stock plant stems, and leaf positions 1 to 3 and 7 to 9 were referred to as mean leaf positions 2 and 8 respectively. Dry weight and …

Characterization of xtcl mutant with reduced cuticular wax accumulation
Cuticular wax is a component of the plant cuticle, the lipid barrier which covers the surface of above ground primary plant organs and plays important protective roles. The isolation of wax deficient mutants from Arabidopsis and other plants resulted in identification and isolation of genes …

Free amino acid composition of flatpea (lathyrus sylvestris L.) as influenced by water-deficit stress, nitrogen fertilization, developmental stage, and rhizobium inoculation
… in leaves and stems increased slightly with plant age. Higher nitrogen availability increased the content of A₂bu in flatpea, a response accompanied by an increase in the contents of soluble protein and other nitrogenous compounds. When exogenous nitrogen supply was decreased, A₂bu levels …
