Genetic Improvement in Resistance to Striga in Tropical Maize Hybrids

Crop Science, Volume 59, Issue 6, Page 2484-2497, November-December 2019., 2019
ABSTRACT Striga hermonthica (Del.) Benth parasitizes maize (Zea mays L.) in sub‐Saharan Africa, causing yield losses of up to 100% under severe infestation. Hybrid maize breeding for polygenic resistance to Striga has been undertaken at the International Institute of Tropical Agriculture (IITA) since the 1980s.

Building a botanical foundation for perennial agriculture: Global inventory of wild, perennial herbaceous Fabaceae species

PLANTS, PEOPLE, PLANET, Volume 1, Issue 4, Page 375-386, October 2019., 2019
Wild, perennial, herbaceous plant species have the capacity to provide both agricultural products and ecological services, such as soil stability and efficient absorption, over multiple years. Although perennial, herbaceous species are common in nature, these species were rarely domesticated.

Stable centromere positioning in diverse sequence contexts of complex and satellite centromeres of maize and wild relatives

Genome Biology, 2017
Background Paradoxically, centromeres are known both for their characteristic repeat sequences (satellite DNA) and for being epigenetically defined. Maize (Zea mays mays) is an attractive model for studying centromere positioning because many of its ...

The Use of Crop Wild Relatives in Maize and Sunflower Breeding

Crop Science, Volume 57, Issue 3, Page 1227-1240, May–June 2017., 2017
Conservation of crop wild relatives (CWR) has always been predicated on the promise of new and useful traits, and thus modern genetics and genomics tools must help fulfill the promise and continue to secure the conservation of these resources. However, the vast genetic potential present in CWR is often difficult to tap, as identification of superior ...

Yield Gains in Extra‐Early Maize Cultivars of Three Breeding Eras under Multiple Environments

Agronomy Journal, Volume 109, Issue 2, Page 418-431, March–April 2017., 2017
Core Ideas The study determined genetic improvement in grain yield of the cultivars during the breeding eras, investigated trait associations, and identified high‐yielding and stable cultivars across multiple‐stress and non‐stress environments. The study revealed an annual genetic gain of 2.72 and 2.28% for the cultivars under multiple‐stress and non ...

Reactive Oxygen Species, Oxidative Damage, and Antioxidative Defense Mechanism in Plants under Stressful Conditions

Journal of Botany, Volume 2012, Issue 1, 2012., 2012
Reactive oxygen species (ROS) are produced as a normal product of plant cellular metabolism. Various environmental stresses lead to excessive production of ROS causing progressive oxidative damage and ultimately cell death. Despite their destructive activity, they are well‐described second messengers in a variety of cellular processes, including ...

Combining Ability of Extra-Early Maize Inbreds Derived from a Cross between Maize and Zea diploperennis and Hybrid Performance under Contrasting Environments

Agronomy, 2020
Knowledge of the genetic mechanisms conditioning drought tolerance in maize is crucial to the success of hybrid breeding programs aimed at developing high-yielding cultivars under drought.

Population dynamics of Zea diploperennis, an endangered perennial herb: effect of slash and burn practice [PDF]

Journal of Ecology, 2002
Summary Zea diploperennis is a wild relative of maize that is endemic to the Sierra de Manantlán Biosphere Reserve in Mexico. Because this species is a priority for conservation in the reserve, the effects on its populations of the most common types of anthropogenic disturbance – slash‐and‐burn, and slash without subsequent burning – were ...

Bacterial endophytes from wild maize suppress Fusarium graminearum in modern maize and inhibit mycotoxin accumulation

Frontiers in Plant Science, 2015
Wild maize (teosinte) has been reported to be less susceptible to pests than their modern maize (corn) relatives. Endophytes, defined as microbes that inhabit plants without causing disease, are known for their ability to antagonize plant pests and ...
