Reactive oxygen species (ROS) regulate plant growth and development. ROS are kept at
low levels in cells to prevent oxidative damage, allowing them to be effective signaling …

In flowering plants, pollen tubes undergo tip growth to deliver two nonmotile sperm to the
ovule where they fuse with an egg and central cell to achieve double fertilization. This …

Directional control of tip-growing cells is essential for proper tissue organization and cell-to-
cell communication in animals and plants,. In the sexual reproduction of flowering plants, the …

Sperm cells of flowering plants are non-motile and thus require transportation to the egg
apparatus via the pollen tube to execute double fertilization. During its journey, the pollen …

In flowering plants, signaling between the male pollen tube and the synergid cells of the
female gametophyte is required for fertilization. In the Arabidopsis thaliana mutant feronia …

For more than 140 years, pollen tube guidance in flowering plants has been thought to be
mediated by chemoattractants derived from target ovules. However, there has been no …

Heat waves induced by climate warming have become common in food-producing regions
worldwide, frequently coinciding with high temperature (HT)-sensitive stages of many crops …

High temperature stress (HTS), during flowering, decreases seed production in many plants.
To determine the effect of a moderate HTS on flowering, fruit and seed set in Brassica …

The term apomixis encompasses a suite of processes whereby seeds form asexually in
plants. In contrast to sexual reproduction, seedlings arising from apomixis retain the …

Research on plant responses to temperature stress is receiving increased interest due to the
growing awareness about global warming. High and low temperature stresses help …
