Many things change during shoot development. Although the most obvious of these is the production of reproductive structures, the morphology and physiology of leaves and vegetative buds changes as well. Some traits change continuously (either increasing or decreasing), while others are expressed in bimodal (present or absent) or even more complex patterns. Some traits vary in the same way in ev...

Induction of milk\disease in 50% of Japanese beetle (Popillia ;apmlica) !aIT,\(' 1)\· feeding requires about IQ1l spores of Bacilllls popilliae per gram of soil. The infectious process occurs in four phases: (1) An initial incubation phase of about :2 da~'s during which there is no evidence of infection in the hemoh-mph. (2) ,-\ \'egetative phase of poJiferation in the hemolymph which lasts unt...

Manganese deficiency in wheat has become an important nutritional disorder particularly in alkaline calcareous soils where rice-wheat rotation is followed. This experiment was aimed to study the mechanism of Mn efficiency during various developmental stages in six wheat cultivars grown at two Mn levels viz. 0 and 50 mg Mn kg(-1) soil (Mnapplied as MnSO4 x H20) in pots. The Mn vegetative efficie...

Some brain injured patients are left in a permanent vegetative state, i.e., they have irreversibly lost their capacity for consciousness but retained some autonomic physiological functions, such as breathing unaided. Having discussed the controversial nature of the permanent vegetative state as a diagnostic category, we turn to the question of the patients' ontological status. Are the permanent...

Vegetative cells and spores of five strains of Alicyclobacillus acidoterrestris (N-1100, N-1108, N-1096, SAC, and OS-CAJ) were screened for their sensitivity to high pressure homogenization (HPH, 0 to 300 MPa) in Bacillus acidoterrestris thermophilic broth. The most and least resistant strains, SAC and OS-CAJ, respectively, were further tested for their sensitivity to inactivation or growth inh...

A non-self-recognition system called vegetative incompatibility is ubiquitous in filamentous fungi and is genetically regulated by het loci. Different fungal individuals are unable to form viable heterokaryons if they differ in allelic specificity at a het locus. To identify components of vegetative incompatibility mediated by allelic differences at the het-c locus of Neurospora crassa, we isol...

The minimally conscious state (MCS) is a clinical manifestation of severe brain injury. While there are no evidence-based criteria, diagnostic guidelines were reached in a series of consensus development workshops [1]. The differential diagnosis of the minimally conscious state is important and includes the vegetative state (transient, persistent and permanent), coma and the locked-in syndrome ...

Plants show phenological responses to herbivory. Some enclosure experiments have demonstrated that the onset of the peak flowering season is dependent on grazing pressure. We constructed a mathematical model using Pontryargin's maximum principle to investigate changes in flowering time by examining shifts in resource allocation from vegetative to reproductive plant components. We represented a ...

RNA polymerase was precipitated from extracts of radioactively labeled vegetative and sporulating Bacillus subtilis with antiserum prepared against vegetative core polymerase. The precipitates were solubilized and analyzed by sodium dodecyl sulfate-polyacrylamide gel electrophoresis. Antiserum added to an extract of vegetative B. subtilis precipitated only the known subunits of core RNA polymer...

The fluxes of (1) exogenous nitrogen (N) assimilation and (2) remobilization of endogenous N from vegetative plant compartments were measured by N labeling during the seed-filling period in pea (Pisum sativum L. cv Caméor), to better understand the mechanism of N remobilization. While the majority (86%) of exogenous N was allocated to the vegetative organs before the beginning of seed filling, ...
