Divisions of labor in the thiamin biosynthetic pathway among organs of maize

Frontiers in Plant Science, 2014
The B vitamin thiamin is essential for central metabolism in all cellular organisms including plants. While plants synthesize thiamin de novo, organs vary widely in their capacities for thiamin synthesis. We use a transcriptomics approach to appraise the

Hormonome Dynamics During Microgametogenesis in Different Nicotiana Species

Frontiers in Plant Science, 2021
Plant microgametogenesis involves stages leading to the progressive development of unicellular microspores into mature pollen. Despite the active and continuing interest in the study of male reproductive development, little is still known about the ...

Pollen development of Rondeletia odorata (Rubiaceae) [PDF]

American Journal of Botany, 2001
Pollen wall ontogeny of Rondeletia odorata was studied with transmission electron microscopy (TEM) and scanning electron microscopy (SEM) from tetrad stage until maturity. The ontogenetic sequence of wall development in Rondeletia follows, to some extent, the basic scheme in the angiosperms, i.e., development starts centripetally with the pro ...

Industrial chicory genome gives insights into the molecular timetable of anther development and male sterility

Frontiers in Plant Science, 2023
Industrial chicory (Cichorium intybus var. sativum) is a biannual crop mostly cultivated for extraction of inulin, a fructose polymer used as a dietary fiber.

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.
