No Mate, No Problem: Molecular Mechanisms Involved in Parthenogenesis in the Cosmopolitan Earthworm Aporrectodea trapezoides (Annelida, Clitellata)

Molecular Ecology, EarlyView.
ABSTRACT Approximately, 40% of earthworm species can reproduce by parthenogenesis. This is the case for the cosmopolitan species, Aporrectodea trapezoides, although sexual forms have been described sporadically. We analyse the genotypes and microbiomes of 30 individuals from four localities where both forms appear in order to understand the ...

An HWE‐Family Histidine Kinase Modulates Brucella Cell Envelope Properties and Host Innate Immune Response

Molecular Microbiology, EarlyView.
The HWE‐family histidine kinase PhyK regulates the cell envelope structure of the intracellular pathogen Brucella ovis and affects how the host immune system responds to this bacterium. Deletion of phyK alters bacterial survival in the face of detergent stress and reduces immune activation in infected macrophages.

Beyond conservation: the landscape of chloroplast genome rearrangements in angiosperms

New Phytologist, EarlyView.
Summary Chloroplast genomes (plastomes) have long been considered structurally conserved, but recent sequencing efforts have uncovered pervasive rearrangements that challenge this assumption. This review catalogues the main types of plastome modifications: large and small inversions; insertions and deletions (indels); gene and intron losses; horizontal

Deciphering the role of monoacylglycerol lipases (MAGL) under abiotic stress and lipid metabolism in soybean (Glycine max L.)

Plant Biotechnology Journal, EarlyView.
Summary Monoacylglycerol lipase (MAGL) is involved in the last step of triacylglycerol breakdown by hydrolysing the monoacylglycerol (MAG) to free fatty acid and glycerol. In the present study, 21 and 38 MAGL genes were identified in Glycine max (cultivated soybean) and Glycine soja (wild) genomes, respectively.

TALEN-mediated depletion of the mitochondrial gene orf312 proves that it is a Tadukan-type cytoplasmic male sterility-causative gene in rice.

The Plant Journal, 2022
Cytoplasmic male sterility (CMS) is a trait that causes pollen or anther dysfunctions, resulting in the lack of seed setting. CMS is considered to be caused by the expression of a unique mitochondrial open reading frame referred to as CMS-associated gene.

Chloroplast DNA and cytoplasmic male-sterility [PDF]

Theoretical and Applied Genetics, 1983
This paper deals with the relationship of chloroplast DNA (ctDNA) and cytoplasmic malesterility (CMS) of maize, wheat and rape. Intramolecular heterogeneity and fragment patterns of DNA digested with restriction endonucleases were compared and analyzed. For this purpose methods of agarose gel electrophoresis and two dimensional gel electrophoresis with

Cytoplasmic Male Sterility in Sorghum

Journal of Heredity, 1972
Anthers of nearly isogenic maintainer and cytoplasmic male-sterile lines of Sorghum bicolor were compared cytologically. Development was similar in fertile and sterile plants during early meiotic prophase and callose "special wall" formation. At this stage callose formation diverged sharply in fertile and sterile anthers.

Cytoplasmic male sterility

The Botanical Review, 1956
Cytoplasmic inheritance is of theoretical importance-it may be of even greater practical importance, for, when it involves malesterility-as in many instances it does-it may make hybridization easier. It may also make possible the use of heterosis in plants otherwise difficult to hybridize.

Cytoplasmic Male Sterility [PDF]

, 1983
The trait cytoplasmic male sterility (cms) is common in higher plants. Edwardson (1) reported that the cms trait had been observed in at least eighty unique plant species. Although the trait may manifest itself in different fashions among the various species, cms plants have in common the inability to produce viable pollen.

Cytoplasmic male sterility in quinoa

Euphytica, 1992
The quinoa cultivar ‘Apelawa’ carries both normal and male sterile cytoplasms. Plants with male sterile cytoplasm produce flowers characterized by the complete absence of anthers and prominent exsertion of stigmas. Intraspecific crosses between male sterile quinoa plants and normal male fertile pollen donors consistently produced male sterile offspring
