Sexual reproduction of plants requires pollen to land on the stigma, which then germinates and grows pollen tubes through the style to deliver sperm cells to the ovule. Pollen tubes are the ...

Rapid alkalinization factors (RALFs) are required for pollen tube germination and elongation, an essential process in plant fertilization. But their role in monocot plants remains unexplored.

Pollen grains may be small but they have a big job. Delivering a sperm to an egg is a little more complicated when the parents don't move around. For plants, pollen success means reaching a receptive ...

Plants with multiple sets of chromosomes, known as polyploids, are salt-tolerant or drought-resistant and often achieve higher yields. However, newly formed polyploid plants are often sterile or have ...

Researchers have shown that the pollen tube of male grain has no issues rising to the occasion. The sexual organ of male grain grows several thousand times its own length in its desire to reach the ...

Flowering seed plants (angiosperms) have evolved unique ways to protect their gametes from pathogen attack and from drying out. The female gametes (egg and central cell) are deeply embedded in the ...

WEST LAFAYETTE, Ind. – Apple growers want to get the most out of their high-value cultivars, and a Purdue University study shows they might want to focus on the types of apples they plant near those ...
