Knowledge remains limited about how fungal pathogens that colonize living plant cells translocate effector proteins inside host cells to regulate cellular processes and neutralize defense responses. To cause the globally important rice blast disease, specialized invasive hyphae (IH) invade successive living rice (Oryza sativa) cells while enclosed in host-derived extrainvasive hyphal membrane. ...

Clubbing is the bulbous enlargement of distal segment digits. It known to be associated with several cardiological, gastrointestinal, pulmonary, neoplastic, infectious, and endocrinological disorders. Rarely clubbing may not associate any underlying pathology despite presenting in a later stage. Here we report case 26- year- old man who presented history recent onset clubbing. Following extensi...

During cellular morphogenesis, changes in cell shape and cell junction topology are fundamental to normal tissue and organ development. Here we show that apoplastic Glycophosphatidylinositol (GPI)-anchored Lipid Transfer Protein (LTPG) is excluded from cell junctions and flat wall regions, and passively accumulates around their borders in the epidermal cells of Arabidopsis thaliana. Beginning w...

'NSU Corynebacteria' are commensals of the normal male and female urogenital tracts (Furness, Kamat, Kaminski, and Seebode, 1973). They are so called because they were first described in association with NSU (Fmrness and Csonka, 1966), and the term is retained so that they should not be confused with other diphtheroids, which in contrast are easily isolated on commercial media and are well-know...

The low-temperature flowering-response pathway, used as an inductive stimulus to induce flowering in plant species from temperate regions in response to cold temperature, has been extensively studied. However, limited information is available on the flower transition of several bulbous species, which require high temperature for flower differentiation. Narcissus tazetta var. chinensis (Chinese ...

The genome of the hemibiotrophic anthracnose fungus, Colletotrichum higginsianum, encodes a large repertoire of candidate-secreted effectors containing LysM domains, but the role of such proteins in the pathogenicity of any Colletotrichum species is unknown. Here, we characterized the function of two effectors, ChELP1 and ChELP2, which are transcriptionally activated during the initial intracel...

In Crocus vernus, a spring bulbous species, prolonged growth at low temperatures results in the development of larger perennial organs and delayed foliar senescence. Because corm growth is known to stop before the first visual sign of leaf senescence, it is clear that factors other than leaf duration alone determine final corm size. The aim of this study was to determine whether reduced growth ...

Colletotrichum higginsianum is a widely distributed fungus attacking many cruciferous species. To investigate pathogenic mechanisms of the pathogen on the host Arabidopsis thaliana, we screened and obtained a virulence-deficient mutant Ch-1-T513 in a T-DNA insertion mutant library of C. higginsianum. The mutant Ch-1-T513 produced yellow colony centers with distorted multi-branching hyphal tips ...

Root hair tip growth provides a unique model system for the study of plant cell polarity. Transgenic plants expressing constitutively active (CA) forms of ROP (Rho-of-plants) GTPases have been shown to cause the disruption of root hair polarity likely as a result of the alteration of actin filaments (AF) and microtubules (MT) organization. Towards understanding the mechanism by which ROP contro...
