Animals exhibit an extraordinary diversity of life history strategies. These realized combinations of survival, development and reproduction are predicted to be constrained by physiological limitations and by trade-offs in resource allocation. However, o
The only ligand–receptor pair identified in anther development so far has been reported in both monocots and dicots:AtTPD1 (TAPETUM DETERMINANT (1):AtEMS1/EXS (EXCESS MALE SPOROCYTES 1/ EXTRA SPOROGENOUS CELLS) inA. thaliana,OsTDL1A (TPD1-LIKE 1A):OsMSP1 (MULTIPLE SPOROCYTE1) in rice,Z...
1.18%); the latter is absent in the miteM. occidentalisgenome and is an ancient trans-kingdom horizontal transfer that can mediate DNA transfer between animals and plants [56]; iv) Members of the superfamily DIRS, encoding tyrosine recombinase frequently involved in site-specific recombination...
During the growth of a clonal culture of the homothallic green flagellate Chlamydomonas geitleriEttl in “batch” culture spontaneous induction of the gametes and their copulation takes place after partial exhaustion of the nitrogen source. Probable precondition of gamete differentiation is cell division...
Predatory mites (Acari: Phytoseiidae) are the most important beneficial arthropods used in augmentative biological pest control of protected crops around the world. However, the genomes of mites are far less well understood than those of insects and the
First identified in mammals, the GnRH signaling pathway is found in all classes of vertebrates; homologues of GnRH have also been identified in invertebrates. In addition to its role as a hypothalamic releasing hormone, GnRH has multiple functions including modulating neural activity within specific ...
Masting, the synchronous and highly variable production of seeds by a population of plants, may periodically synchronize over large portions of a species distribution range1,2,3, with major cascading effects on ecosystems functioning4. Large-scale masting events rely on the spatial synchronization (...
Plants in the family Cucurbitaceae fail to produce fruit when pollination does not occur with the exception of hybrid variants only with female flowers. Cucumbers usually have female and male flowers on the same plant, meaning that they are self-pollinating and do not have to receive pollen from...
