Interspecific somatic hybrids between Solanum bulbocastanum and S. tuberosum and their haploidization for potato breeding [PDF]

Biologia Plantarum, 2012
Protoplast fusion between incongruent Solanum bulbocastanum and S. tuberosum haploids was accomplished to produce hybrids combining elite traits from both parents. We identified 11 somatic hybrids out of 42 regenerants analyzed through ISSR markers. Some

Comparative insights into molecular pathways influencing germline development in early-divergent angiosperms. [PDF]

Plant J
SUMMARY The molecular and genetic mechanisms regulating female germline development remain largely unknown in basal and early‐divergent angiosperms. This contrasts with recent progress in model eudicots such as Arabidopsis thaliana and monocots, such as rice, barley, and maize. In this study, we investigate the genetic pathway governing female germline

Editing of ORF138 restores fertility of Ogura cytoplasmic male sterile broccoli via mitoTALENs. [PDF]

Plant Biotechnol J
Summary Cytoplasmic male sterility (CMS), encoded by the mitochondrial open reading frames (ORFs), has long been used to economically produce crop hybrids. However, the utilization of CMS also hinders the exploitation of sterility and fertility variation in the absence of a restorer line, which in turn narrows the genetic background and reduces ...

The carnivorous rainbow plant Byblis filifolia Planch. secretes digestive enzymes in response to prey capture independently of jasmonates. [PDF]

Plant Biol (Stuttg)
Secretion of digestive enzymes in response to prey capture in carnivorous plants with sticky traps is regulated by jasmonates in Drosera capensis but differently by unknown factor in Byblis filifolia. Abstract Carnivorous plants from the order Caryophyllales co‐opted plant phytohormones from a group of jasmonates to regulate digestive enzyme activity ...

Effects of Alternaria alternata f.sp. lycopersici toxins on pollen [PDF]

, 1988
Effects of the phytotoxic compounds (AAL-toxins) isolated from cell-free culture filtrates of Alternaria alternata f.sp. lycopersici on in vitro pollen development were studied. AAL-toxins inhibited both germination and tube growth of pollen from several

Microgametophyte Development in Cannabis sativa L. and First Androgenesis Induction Through Microspore Embryogenesis

Frontiers in Plant Science, 2021
Development of double haploids is an elusive current breeding objective in Cannabis sativa L. We have studied the whole process of anther and pollen grain formation during meiosis, microsporogenesis, and microgametogenesis and correlated the different ...

Patterns of amyloplast distribution during microsporogenesis in Tradescantia, Impatiens and Larix

Acta Societatis Botanicorum Poloniae, 2014
During the meiotic prophase I in Tradescantia and Impatiens microsporocyte becomes temporarily asymmetric, with excentrically situated nucleus and all amyloplasts gathered in a dense group close to the nuclear envelope..

Külföldi kajszifajták adaptációs értékelése a virágrügyfejlődés, a fagyérzékenység és a gyümölcsminőség vizsgálata alapján = Adaptation evaluation of foreign apricot cultivars based on their flower bud development, frost hardiness, and fruit quality [PDF]

, 2016
Napjainkban a kajszinemesítés legfontosabb célkitűzései közé tartozik a gyümölcsminőség javítása mellett a fajták abiotikus és biotikus stresszel szemben való ellenállóságának fokozása.

Introduction of barnase/barstar in soybean produces a rescuable male sterility system for hybrid breeding

Plant Biotechnology Journal, Volume 21, Issue 12, Page 2585-2596, December 2023., 2023
Summary Hybrid breeding for increased vigour has been used for over a century to boost agricultural outputs without requiring higher inputs. While this approach has led to some of the most substantial gains in crop productivity, breeding barriers have fundamentally limited soybean (Glycine max) from reaping the benefits of hybrid vigour.

The development rhythm of the flower-bud in some Papilionaceae species. Part II. Microsporogenesis, macrosporogenesis and early gametogenesis in Pisum sp. forms against the background of bud development

Acta Societatis Botanicorum Poloniae, 2015
The process of microsporogenesis and development of pollen grains was found to occur in an identical rhythm in 14 examined forms of Pisum sp. as compared with the development of the perianth. In the 3 forms studied in detail: Pisum sativum L.
