Development and validation of red root marker-based haploid inducers that effectively complement R1-nj (Navajo) marker-based in vivo haploid identification in maize

, 2016
One of the critical limitations for the in vivo production of doubled haploid (DH) lines in maize (Zea mays L.) is the inability to effectively identify haploids in a significant proportion of induction crosses due to the possibility of complete or ...

Somatic and haploid embryo development in Arabidopsis

, 2020
Somatic embryogenesis is the ability of a vegetative cell to develop into an embryo, either naturally or in vitro, in tissue culture. It is an excellent model to study plant cell totipotency (the ability to regenerate a whole new plant through ...

Multiple Roles of Protamine Kinase SRPK1 and Phosphatase PP1γ in Sperm Development

PROTEOMICS, EarlyView.
ABSTRACT Protein phosphorylation regulates key events of male germ cell differentiation. In the testis, SRPK1 and PP1γ are involved in protamine phosphorylation and dephosphorylation, respectively, and their deregulation is linked to defective chromatin structure and male infertility.

Elite, transformable haploid inducers in maize

Crop Journal
The introduction of alleles into commercial crop breeding pipelines is both time consuming and costly. Two technologies that are disrupting traditional breeding processes are doubled haploid (DH) breeding and genome editing (GE).

A DMP-triggered in vivo maternal haploid induction system in the dicotyledonous Arabidopsis

, 2020
Doubled haploid technology using inducer lines carrying mutations in ZmPLA1/MTL/NLD and ZmDMP1–4 has revolutionized traditional maize breeding. ZmPLA1/MTL/NLD is conserved in monocots and has been used to extend the system from maize to other monocots5–7,

A synthetic eco‐evolutionary proposal for the conservation of wild relatives of the olive tree

PLANTS, PEOPLE, PLANET, EarlyView.
Societal Impact Statement Crop wild relatives (CWR) are valuable sources of genetic diversity for plant breeding. However, the identification of wild untapped genetic resources (i.e., unexploited in crops) is not always straightforward. We propose a methodology to guide the identification and conservation of these resources that integrates both genetic

Doubled haploid technology for line development in maize: technical advances and prospects

, 2019
Doubled haploid (DH) technology has become an integral part of many commercial maize breeding programs as DH lines offer several economic, logistic and genetic benefits over conventional inbred lines.

Identification of novel QTL for resistance to crown rot in the doubled haploid wheat population 'W21MMT70' x 'Mendos' [PDF]

, 2006
Crown rot (causal agent Fusarium pseudograminearum) is a fungal disease of major significance to wheat cultivation in Australia. A doubled haploid wheat population was produced from a cross between line 'W21MMT70', which displays partial seedling and ...

Gene turnover in the common ancestor of all C4 grasses

PLANTS, PEOPLE, PLANET, EarlyView.
Understanding how plants evolve more efficient photosynthesis is important in a warming world where improving crop productivity and resilience is a global priority. By generating the first reference genomes for an early‐diverging group of grasses called the Aristidoideae, we were able to reconstruct the genetic makeup of the last common ancestor of all

Doubled haploid breeding: Incorporating spontaneous haploid genome doubling in maize breeding programs

Maize (Zea mays L.) is a globally significant cereal crop, essential to food security, animal feed, and industrial applications (Nuss and Tanumihardjo, 2010).
