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.

Molecular cloning and bioinformatic analysis of pollen development related gene BcMF2r from Brassica campestris L. spp. rapifera

浙江大学学报. 农业与生命科学版, 2006
BcMF2r gene, homologous with the BcMF2 gene encoding pollen-specific polygalacturonase of Chinese cabbage-pak-choi, was cloned from turnip (Brassica campestris L. spp. rapifera).

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 ...

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.

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.

Peat initiation in the Faroe Islands: climate change, pedogenesis, or human impact? [PDF]

, 2007
As an isolated island group lying off the NW European mainland which was uninhabited until the mid-first millennium AD, the Faroes offer a unique opportunity to study natural processes of Holocene ecosystem development in a region where anthropogenic ...
