Conservation challenges and opportunities for native apple (Malus) species in Canada

PLANTS, PEOPLE, PLANET, EarlyView.
Apple, one of the world's most widely cultivated and economically important fruit crops, has two wild relatives native to Canada. In this review, we describe the importance of these native apple species to Indigenous heritage and the current threats the species faces due to pests, diseases, and habitat loss.

Global analysis of the sugarcane microtranscriptome reveals a unique composition of small RNAs associated with axillary bud outgrowth [PDF]

, 2013
Axillary bud outgrowth determines shoot architecture and is under the control of endogenous hormones and a fine-tuned gene-expression network, which probably includes small RNAs (sRNAs).

Preliminary genetic barcodes for ash (Fraxinus) species and generation of new wide hybrids

PLANTS, PEOPLE, PLANET, EarlyView.
Societal Impact Statement The world‐wide diversity of ash trees includes genetic information encoding resistance to the ash dieback fungus and the emerald ash borer beetle, which are currently devastating ash populations in Europe and North America. In order to mobilise this genetic diversity in conventional breeding programmes, we need to be able to ...

Identification of Three POMCa Genotypes in Largemouth Bass (Micropterus salmoides) and Their Differential Physiological Responses to Feed Domestication

Animals
Diverse feeding habits in teleosts involve a wide range of appetite-regulating factors. As an appetite-suppressing gene, the polymorphisms of POMCa in largemouth bass (Micropterus salmoides) were validated via sequencing and high-resolution melting (HRM).

Roles of Polyploid/Multinucleated Giant Cancer Cells in Metastasis and Disease Relapse Following Anticancer Treatment

Cancers, 2018
Tumors and tumor-derived cell lines contain polyploid giant cells with significantly elevated genomic content, often with multiple nuclei. The frequency of giant cells can increase markedly following anticancer treatment.

Resolving phylogeny and polyploid parentage using genus-wide genome-wide sequence data from birch trees

bioRxiv, 2020
Numerous plant genera have a history including frequent hybridisation and polyploidisation, which often means that their phylogenies are not yet fully resolved. The genus Betula, which contains many ecologically important allopolyploid tree species, is a

Molecular phylogeny, genome sizes and chromosome numbers in melic grasses and its relatives (Pooideae, Poaceae) with a revised classification of the genus Melica

TAXON, EarlyView.
Abstract The genus Melica comprises around 90 species, which are widespread throughout the temperate and subtropical regions of the world. In contrast to numerous species complexes in the grass subfamily Pooideae, the genus Melica forms a very homogeneous group of mainly diploid species with a uniform basic chromosome number of x = 9.

Chromosome Pairing in Polyploid Grasses

Frontiers in Plant Science, 2020
Polyploids are species in which three or more sets of chromosomes coexist. Polyploidy frequently occurs in plants and plays a major role in their evolution.

Accumulating time lags across biodiversity levels following land‐use change

Journal of Ecology, EarlyView.
Species identity seems central in governing the observed delays at each level of biodiversity, from genetic to functional diversity. In particular, species identity controls the slowest responses at the genetic level, potentially leading to accumulating underestimations of the size and duration of time lags at species, community and functional ...
