Rice Immature Pollen 1 (RIP1) is a Regulator of Late Pollen Development [PDF]

Plant and Cell Physiology, 2006
We isolated a pollen-preferential gene, RICE IMMATURE POLLEN 1 (RIP1), from a T-DNA insertional population of japonica rice that was trapped by a promoterless beta-glucuronidase (GUS) gene. Semi-quantitative reverse transcription-PCR (RT-PCR) analyses confirmed that the RIP1 transcript was abundant at the late stages of pollen development.

Higher Temperature at Lower Elevation Sites Fails to Promote Acclimation or Adaptation to Heat Stress During Pollen Germination

Frontiers in Plant Science, 2018
High temperatures associated with climate change are expected to be detrimental for aspects of plant reproduction, such as pollen viability. We hypothesized that (1) higher peak temperatures predicted with climate change would have a minimal effect on ...

Male Meiosis as a Biomarker for Endo- to Ecodormancy Transition in Apricot

Frontiers in Plant Science, 2022
Dormancy is an adaptive strategy in plants to survive under unfavorable climatic conditions during winter. In temperate regions, most fruit trees need exposure to a certain period of low temperatures to overcome endodormancy.

Pollen Development

, 2018
AbstractPollen is source and transport unit for the male gametes (or their progenitor cell). The unicellular pollen grain represents the microspore of seed plants, the multicellular pollen grain the male gametophytic generation. The development of a pollen grain includes microsporogenesis and microgametogenesis (Figs. 1 and 2, Gomez et al.

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

Comparative Pollen Development in Dioscoreales [PDF]

International Journal of Plant Sciences, 2005
Pollen and orbicule ontogeny in representatives of three genera of Dioscoreales—Narthecium ossifragum Huds. (Nartheciaceae), Tacca artocarpifolia Seem. and Tacca chantrieri Andre (Dioscoreaceae), and Dioscorea communis (L.) Caddick & Wilkin (Dioscoreaceae)—is described and illustrated using LM, SEM, and TEM. The main difference is in microsporogenesis,

RNA-seq analysis of synchronized developing pollen isolated from a single anther

Frontiers in Plant Science, 2023
Pollen development, from unicellular microspores to anthesis, is a complex process involving the coordinated specification, differentiation and functions of different cell types. Key to understanding this development is identifying the genes expressed at

Pollen grain of barley (Hordeum vulgare L.) - pattern of development

Acta Societatis Botanicorum Poloniae, 2014
Pollen development in barley follows the general pattern established for other species of Poaceae: 1) microspore division occurs at the vacuolate microspore stage with polarly located nucleus; 2) microspore mitosis is immediately followed by phragmoplast

Crop Pollen Development under Drought: From the Phenotype to the Mechanism

International Journal of Molecular Sciences, 2019
Drought stress induced pollen sterility is a harmful factor that reduces crop yield worldwide. During the reproductive process, the meiotic stage and the mitotic stage in anthers are both highly vulnerable to water deficiency.

Ensuring Reproduction at High Temperatures: The Heat Stress Response during Anther and Pollen Development

Plants, 2013
Sexual reproduction in flowering plants is very sensitive to environmental stresses, particularly to thermal insults which frequently occur when plants grow in field conditions in the warm season.
