Rhodobacter johrii sp. nov., an endospore-producing cryptic species isolated from semi-arid tropical soils [PDF]

open access: yes, 2010
An oval to rod shaped phototrophic purple nonsulfur bacterium, strain JA192T was isolated from an enrichment culture of a pasteurized rhizosphere soil sample of jowar crop collected from Godumakunta village, near Hyderabad, India.

Penicillium rubens germination on desiccated and nutrient-depleted conditions depends on the water activity during sporogenesis.

open access: yesFungal Biology, 2020
Fungal growth often appears in a surrounding where water and nutrients are scarce. The impact of this environment during sporogenesis on subsequent growth is often neglected. This study investigates the effect of water availability during sporogenesis on

Hybridization between wild and cultivated potato species in the Peruvian Andes and biosafety implications for deployment of GM potatoes [PDF]

open access: yes, 1976
The nature and extent of past and current hybridization between cultivated potato and wild relatives in nature is of interest to crop evolutionists, taxonomists, breeders and recently to molecular biologists because of the possibilities of inverse gene ...

Imaging plant germline differentiation within Arabidopsis flowers by light sheet microscopy [PDF]

open access: yes, 2020
In higher plants, germline differentiation occurs during a relatively short period within developing flowers. Understanding of the mechanisms that govern germline differentiation lags behind other plant developmental processes.

Aggregations of organelles in meiotic cells of higher plants

open access: yesActa Societatis Botanicorum Poloniae, 2014
During early prophase I in microsporocytes and sporocytes of various plants all mitochondria and plastids aggregate in a group, where some plastids seem to undergo division. This group desintegrates by middle prophase I.

Dynamic changes of small RNAs in rice spikelet development reveal specialized reproductive phasiRNA pathways [PDF]

open access: yes, 2016
Dissection of the genetic pathways and mechanisms by which anther development occurs in grasses is crucial for both a basic understanding of plant development and for examining traits of agronomic importance such as male sterility.

Origin of the Diplazium hachijoense complex (Athyriaceae) [PDF]

open access: yesPhytoKeys, 2019
We analyzed the phylogeny of the Diplazium hachijoense complex using plastid trnL-F and low-copy nuclear marker AK1 DNA sequences. Based on allele constitution, triploid apogamous species of the D. hachijoense complex appeared to have originated from the

Elevated temperature drives a shift from selfing to outcrossing in the insect pollinated legume, faba bean (Vicia faba) [PDF]

open access: yes, 2016
Climate change can threaten the reproductive success of plants, both directly, through physiological damage during increasingly extreme weather events, and indirectly, through disruption of plant–pollinator interactions.

Estudos sobre a esporulação de uma amostra de bacillus: III - Influência da concentração da glicose sobre o início da esporogênese

open access: yesMemorias do Instituto Oswaldo Cruz, 1973
Células do Bacillus licheniformis 2390 foram cultivadas em um meio semi-sintético, a fim de se observar uma possível influência de diferentes concentrações de glicose sobre o tempo necessário para o início da esporogênese.
