Genetic variability of anther donor versus spontaneous doubled haploid descendents and colchicine induced doubled haploid sweet pepper (Capsicum annuum L.) lines [PDF]

open access: yes, 2001
Haploid (n) and doubled haploid (DH) plants were developed in anther culture of sweet pepper (Capsicum annuum L.). Regenerants were analyzed by flow cytometry for haploid (n = 12) and spontaneous doubled haploid (2n = 24) genomes.

Engineering a Gibberellin‐Switchable Dual‐Use Line Based on Ent‐Kaurene Oxidase Gene ZmKO1 Enables Two‐Line Hybrid Seed Production in Maize

open access: yesPlant Biotechnology Journal, EarlyView.
ABSTRACT Male‐sterile systems are pivotal for maize hybrid seed production, yet existing systems are constrained by significant limitations. Here, we identified a novel single‐gene‐controlled recessive genic male sterility (GMS) mutant, defective in filament elongation 1 (def1), which exhibits non‐elongated filaments, unopened glumes, and non‐exserted ...

Microspore embryogenesis in Apiaceae

open access: yesPlant Cell, Tissue and Organ Culture (PCTOC), 2010
Haploid technology is used to develop uniform, true-breeding lines, as well as to accelerate crop improvement programs. Among 20 Apiaceae species screened for response to doubled haploidy, 11 generated microspore-derived embryos, and all but one of the latter yielded doubled haploid plants.

Doubled Haploid production in fruit crops. [PDF]

open access: yes, 2006
The interest of fruit breeders in haploids and doubled haploids (DH), lies in the possibility of shortening the time needed to produce homozygous lines compared to conventional breeding.

The Rice Cis‐Natural Antisense Transcript NAT1850 of Pri‐miR1850 Negatively Regulates Cold Tolerance by Repressing NPR3

open access: yesPlant Biotechnology Journal, EarlyView.
ABSTRACT Natural antisense transcripts (NATs) correspond to nearly 60% of annotated rice loci, however their functions are largely unknown. In this study, we characterise a rice cis‐NAT (NAT1850) that completely overlaps with a rice‐specific primary miRNA, pri‐miR1850.

Cytological development, calcium dynamic and metabolite profile of stress-induced tobacco (Nicotiana tabacum L.) microspore under calcium chloride treatment [PDF]

open access: yesBrazilian Journal of Biology
Exogenous calcium is pivotal in activating microspore embryogenesis via calcium signaling. Altering the external calcium levels in the medium has been documented to impact the success rate of microspore embryogenesis initiation.

BnPME is progressively induced after microspore reprogramming to embryogenesis, correlating with pectin de-esterification and cell differentiation in Brassica napus

open access: yesBMC Plant Biology, 2016
Pectins are one of the main components of plant cell walls. They are secreted to the wall as highly methylesterified forms that can be de-esterified by pectin methylesterases (PMEs).

Redundant Glycerol‐3‐Phosphate Acyltransferases Regulate Thermo‐Sensitive Genic Male Sterility in Rice

open access: yesPlant Biotechnology Journal, EarlyView.
ABSTRACT Thermo‐sensitive genic male sterility (TGMS) lines play a pivotal role in two‐line hybrid rice breeding. However, the availability of elite TGMS germplasm remains limited, and the molecular mechanisms underlying fertility transition of TGMS lines are still poorly understood.

Generic Workflow of a Highly Effective and Easy Anther Culture Method for Both Japonica and Indica Rice

open access: yesPlants
As one of the most important staple crops in the world, rice plays a pivotal role in world food security. The creation of doubled haploids based on anther culture is an important technology for rice breeding.

Comparison of methods for obtaining doubled haploids of carrot

open access: yesActa Societatis Botanicorum Poloniae, 2017
Doubled haploid lines of carrot can be obtained through androgenesis in anther cultures and in isolated microspore cultures. The two methods were compared using three carrot cultivars (‘Kazan F1’, ‘Feria F1’, and ‘Narbonne F1’) at the androgenesis ...
