Microsporogenesis of Apricot Cultivars in Hungary

Notulae Botanicae Horti Agrobotanici Cluj-Napoca, 2013
Like all phenological processes, microsporogenesis is mainly determined genetically, but its phenotypical expression is greatly influenced by environmental factors, particularly the temperature.

Methodologies and Considerations in Evaluating Heat Stress Response and Thermotolerance of Pollen Grains. [PDF]

Physiol Plant
ABSTRACT Elevated temperatures severely disrupt pollen function, posing a major threat to agricultural productivity. While research into pollen thermotolerance is rapidly expanding, the quest to identify and develop heat‐tolerant crops is challenged by a lack of consistent methodological considerations and experimental design principles.

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

Microsporogenesis and systematics of Aristolochiaceae [PDF]

Botanical Journal of the Linnean Society, 2001
Within Aristolochiaceae, a secretory tapetum and orbicules are ubiquitous, but both simultaneous and successive types of microsporogenesis occur. Simultaneous cytokinesis is apparently plesiomorphic within the order Piperales, in which Aristolochiaceae are now placed.

Polyamines in Pollen: From Microsporogenesis to Fertilization [PDF]

Frontiers in Plant Science, 2016
The entire pollen life span is driven by polyamine (PA) homeostasis, achieved through fine regulation of their biosynthesis, oxidation, conjugation, compartmentalization, uptake, and release. The critical role of PAs, from microsporogenesis to pollen-pistil interaction during fertilization, is suggested by high and dynamic transcript levels of PA ...

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

Kanamycin resistance during in vitro development of pollen from transgenic tomato plants [PDF]

, 1987
Effects of kanamycin on pollen germination and tube growth of pollen from non-transformed plants and from transgenic tomato plants containing a chimaeric kanamycin resistance gene were determined. Germination of pollen was not affected by the addition of

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..

Microsporogenesis of peach (Prunus persica L. Batsch) varieties

International Journal of Horticultural Science, 2002
Bud dormancy during winter is a critical factor in peach production in Hungary. The yield is determined basically by the survival rate of flower buds during winter frosts and by their ability to develop normal floral organs.

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.
