BACKGROUND AND AIMS Brachypodium is a small genus of temperate grasses that comprises 12-15 species. Brachypodium distachyon is now well established as a model species for temperate cereals and forage grasses. In contrast to B. distachyon, other members of the genus have been poorly investigated at the chromosome level or not at all. METHODS Twenty accessions comprising six species and two su...

Lipoarabinomannan (LAM) is a component of the mycobacterial surface which has been associated with a variety of deleterious effects on immune system function. Despite the importance of LAM to the pathogenesis of mycobacterial infection, there is no information available on its fate in vivo. In this study, we determined the pharmacokinetics and tissue distribution of exogenously administered LAM...

In an earlier study of the diurnal variation of organic acids and starch in excised leaves of Bryophyllum calycinum (3), it was observed that the quantity of isocitric acid present did not change significantly during a threeday period of culture in water under greenhouse conditions of illumination. Because of the contrast between the behavior of this substance and that of malic and citric acids...

Cellulose-minus mutants of Agrobacterium tumefaciens retain virulence but can be removed from wound sites by washing with water. Washing of Bryophyllum diagremontiana leaves inoculated with a cellulose-minus mutant was used to determine the minimum time the bacteria must be present for tumor induction. This time was 4 to 8 h.

Lymphangioleiomyomatosis (LAM) is a progressive disorder of unknown etiology that predominantly affects the lungs, and the resulting respiratory failure can be fatal. Extrapulmonary LAM is a rare disease that often occurs concurrently with pulmonary LAM. Usually, extrapulmonary LAM presents as a localized, well-circumscribed mass. Due to the rare occurrence of extrapulmonary LAM and its atypica...

A 3 × 2 factorial experiment was conducted to investigate the effects of different ratios of dietary laminarin (LAM) and fucoidan (FUC) on growth performance and nutrient digestibility in newly weaned piglets. At weaning, 168 piglets (24 d of age; 6.8 kg live weight) were assigned to 1 of 6 dietary treatments (n = 14/treatment): (i) basal diet, (ii) basal diet + 240 mg/kg FUC, (iii) basal diet ...

1. In Bryophyllum calycinum two apical leaves suppress the shoot formation in all the dormant buds situated basally from the leaf; one apical leaf suppresses the shoot formation in the basal buds situated in the same half of the stem where the leaf is, and, if one-half of the petiole of such a leaf is removed, the growth of basal buds in one quadrant of the stem is suppressed. 2. This inhibitor...

1. It has been shown that there is a diurnal change in the H ion concentration in Bryophyllum calycinum corresponding approximately to the total acidity changes. The H ion concentration increases at night and decreases during the day. 2. Light is the main factor in causing the decrease in acidity, though it also occurs in the dark. but much more slowly. 3. External oxygen tension does not seem ...
