Carbon source influences Saccharomyces cerevisiae yeast cell survival strategies: quiescence or sporulation

open access: yesBiotechnology & Biotechnological Equipment, 2019
When starving, diploid Saccharomyces cerevisiae yeasts can enter into at least two stable non-dividing states – sporulation or quiescence – and thus survive unfavorable conditions for long periods of time.

COMPARISON OF GRAPE SEEDLINGS POPULATION AGAINST DOWNY MILDEW BY USING DIFFERENT PROVOCATION METHODS

open access: yesNotulae Botanicae Horti Agrobotanici Cluj-Napoca, 2007
This research was conducted to compare a laboratory technique leaf disk with hotbed and field evaluations in the screening of large populations of grape seedlings (Vitis spp.), towards downy mildew (Plasmopara viticola Berk.

Effects of culture conditions on the growth and morphology of 20 strains of Drechslera avenae (Eidam) Scharif

open access: yesActa Agrobotanica, 2012
Growth and sporulation of 20 single-spore isolates of Drechslera avenae grown on different agar media were investigated at 24°C and 11°C. Four different agar media were used - water agar (WA, 20 g agar x l-1), maltose-peptone agar (MPA, 20 g maltose from

Dysregulated biosynthesis and hydrolysis of cyclic-di-adenosine monophosphate impedes sporulation and butanol and acetone production in Clostridium beijerinckii NCIMB 8052

open access: yesFrontiers in Bioengineering and Biotechnology
IntroductionAlthough solventogenic Clostridium species (SCS) produce butanol, achieving high enough titers to warrant commercialization of biobutanol remains elusive. Thus, deepening our understanding of the intricate cellular wiring of SCS is crucial to

Methods of inoculating cypress with Seridium species to screen for resistance and pathogen variability : a thesis presented in partial fulfilment of the requirements for the degree of Master of Applied Science in Plant Health at Massey University, Palmerston North, New Zealand [PDF]

open access: yes, 2003
The cypress species are grown for their timber value, ornamental beauty and shelter. Their existence is threatened by the presence of cypress canker disease caused by fungal pathogens of the genus Seiridium.

Immunization with peptide encapsulated within synthetic spores activates T cell responses and reduces tumor growth

open access: yesmBio
Peptide-based therapeutic immunizations represent safe approaches to elicit antigen-specific T cell responses, but their broad utility remains limited due to poor immunogenicity and short in vivo stability due to rapid degradation and clearance. Here, we

Evolving a plant-beneficial bacterium in soil vs. nutrient-rich liquid culture has contrasting effects on in-soil fitness

open access: yesApplied and Environmental Microbiology
Inoculation of plant-beneficial microbes into agricultural soils can improve crop growth, but such outcomes depend on microbial survival. Here, we assessed how exposure to prior environmental conditions impacts microbial in-soil fitness, particularly ...

Autoinducer-2 relieves soil stress-induced dormancy of Bacillus velezensis by modulating sporulation signaling

open access: yesnpj Biofilms and Microbiomes
The collective behavior of bacteria is regulated by quorum sensing (QS). Autoinducer-2 (AI-2) is a common QS signal that regulates the behavior of both Gram-positive and Gram-negative bacteria. Despite the plethora of processes described to be influenced

Sporulation at reduced water activity impairs germination kinetics of Bacillus subtilis spores

open access: yesApplied and Environmental Microbiology
While the effect of sporulation temperature on spore germination has been extensively studied, the effect of other relevant environmental factors such as water activity (aw) has been overlooked, despite the fact that sporulation niches with lower ...

Segregation of sister chromosomes during the shape change of developing Myxococcus xanthus cells

open access: yesJournal of Bacteriology
Chromosome organization is critical for the maintenance of genetic integrity. Most studies of bacterial nucleoids have focused on growing rod-shaped organisms. Studying nucleoid dynamics during Myxococcus xanthus development offers the unique opportunity
