Genomic structure and ex situ conservation of the North American grapevine Vitis labrusca

PLANTS, PEOPLE, PLANET, EarlyView.
The North American wild grapevine species Vitis labrusca is an important source of disease resistance and climate resilience traits for breeding new grapevine cultivars. To ensure its continued use in breeding, V. labrusca must be accurately identified and genetically diverse material must be conserved.

A century of theories of balancing selection

Biological Reviews, EarlyView.
ABSTRACT Traits that affect organismal fitness are often highly genetically variable. This genetic variation is vital for populations to adapt to their environments, but it is also surprising given that nature – after all – ‘selects’ the best genotypes at the expense of those that fall short.

The life cycles of cryptogams [PDF]

, 1991
Meiosis and karyogamy are recognized as control points in the life cycle of cryptogams. The control of meiosis is evidently complex and in yeast, and by analogy in all cryptogams, involves progressive gene activation.

Embryological studies inMecardonia procumbens (Miller) small [PDF]

, 1983
Sporogeneses, development of gametophytes, endosperm and embryo ofMecardonia procumbens (Miller) Small have been described. The wall of the microsporangium consists of an epidermis, an endothecium, a middle layer and a glandular tapetum.

Purified and specific cytoplasmic pollen extract: a non-hormonal alternative for the treatment of menopausal symptoms. [PDF]

, 2020
Research into non-hormonal, alternative therapies is necessary for women for whom menopausal hormone therapy is contraindicated or for women who do not wish to take hormones.

Transposable element‐mediated DNA methylation of the NAC20 and NAC26 promoters led to a maternal effect on grain filling

Journal of Integrative Plant Biology, EarlyView.
The rice transcription factor genes NAC20 and NAC26 regulate grain filling and show allele‐specific maternal expression due to transposable element insertions and paternal hypermethylation in their 5' upstream regions. Geographical analyses showed that japonica varieties that originated at high latitudes carried these transposable elements.

A Tobacco Homolog of DCN1 is Involved in Cellular Reprogramming and in Developmental Transitions [PDF]

, 2011
Plant proteomes show remarkable plasticity in reaction to environmental challenges and during developmental transitions. Some of this adaptability comes from ubiquitin-mediated protein destruction regulated by cullin-RING E3 ubiquitin ligases (CRLs ...

Electron microscopy‐based three‐dimensional subcellular imaging of plant male gametophyte

Journal of Integrative Plant Biology, EarlyView.
The Aquilos2 Cryo‐FIB workflows provide practical routes for cryo‐electron tomography and volume imaging in plant structural biology. ABSTRACT Understanding cellular events in three dimensions (3D) is of great importance for the annotation and illustration of biological processes in a contextual way. Imaging techniques based on electron microscopy (EM),

Proline synthesis in developing microspores is required for pollen development and fertility [PDF]

, 2018
Background: In many plants, the amino acid proline is strongly accumulated in pollen and disruption of proline synthesis caused abortion of microspore development in Arabidopsis.

An investigation into the efficacy of Biokos® in controlling ciliates in laboratory cultures of Saccharina latissima gametophytes

Journal of Phycology, EarlyView.
Abstract A major challenge faced by kelp aquaculture operations is the control of contaminants, including by marine ciliates. Biokos® is a commercially available treatment for ciliate parasites in fish, in which the active ingredient is a viscosin‐like lipopeptide surfactant.
