Aggregations of organelles in meiotic cells of higher plants
Acta 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]
, 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]
PhytoKeys, 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

Sporogenesis and Toxin a Production by Clostridium Difficile [PDF]
Journal of Medical Microbiology, 1986 The kinetics of spore production by Clostridium difficile were not paralleled by release of C. difficile toxin A in vitro. Toxin A was not found to be associated with either purified whole spores or spore coats. Residual traces of toxin A detected in spore contents were almost certainly derived from contaminating vegetative cell debris.

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

SEXUAL STERILITY is Essential for Both Male and Female Gametogenesis in Tomato [PDF]
, 2017 Gametogenesis is a key step in the production of ovules or pollen in higher plants. The molecular aspects of gametogenesis are well characterized in the model plant Arabidopsis; however, little information is known in tomato, which is a model plant for ...
