Poliembrionía en maices de porte normal y enano.

Agronomía Mesoamericana, 2016
El Instituto Mexicano del Maíz (IMM) ha generado poblaciones de maíz, que incluyen la caracteóstica de poliembrionía (PE). El fenómeno es de interés considerando que dos o más embriones por semilla pudieran significar un mayor contenido de aceite y ...

Assessing the Corn Belt as an anthropogenic barrier to migrating landbirds in the United States

Conservation Biology, EarlyView.
Abstract Migrating landbirds adjust their flight and stopover behaviors to efficiently cross inhospitable geographies, such as the Gulf of Mexico and the Sahara Desert. In addition to these natural barriers, birds may increasingly encounter anthropogenic barriers created by large‐scale changes in land use. One such barrier could be the Corn Belt in the

Nation‐Building in the Wake of Empire: Identifying Patterns of Minority Policies in the Aftermath of Soviet Collapse

Nations and Nationalism, EarlyView.
ABSTRACT The collapse of the USSR forced newly independent states to forge national identities while grappling with imperial legacies. This study investigates nation‐building strategies in post‐Soviet states during 1990–1999, using the Nation‐Building Policies (NBP) dataset from the ETHNICGOODS project, which includes all socially and politically ...

Young maize plants impact the bacterial community in Australian cotton‐sown vertisol more than agricultural practices

Environmental Microbiology Reports, Volume 17, Issue 3, June 2025.
In an irrigated Vertisol, different cotton farming systems affected only a few bacterial groups and potential metabolic functions. However, the application of maize plants or their neutral detergent fibre fraction had a significant impact on many of them. Abstract Changes in soil characteristics due to varying farming practices can modify the structure

Exploiting barley landraces to reintroduce lost genetic diversity: Resistance to net form net blotch

Crop Science, Volume 65, Issue 3, May/June 2025.
Abstract Centuries of barley (Hordeum vulgare) domestication and selection has resulted in reduced genetic diversity in modern cultivars, limiting breeder's options to select desirable traits. Barley landraces, heirloom varieties, and wild relatives are substantially more variable and can be exploited to reintroduce favorable genes and alleles.

Oaxacan Green Dent maize is not from Oaxaca

Crop Science, Volume 65, Issue 2, March/April 2025.
Abstract Oaxacan Green Dent is a maize (Zea mays L.) cultivar marketed as an introduced Mexican heritage cultivar adapted to the higher latitudes of the United States. Its adaptation and appearance contradict an origin in Oaxaca, Mexico, however, and no indigenous cultivars in Oaxaca are known to have the unique kernel colors of Oaxacan Green Dent.
