Plant cells must react to a variety of adverse environmental conditions that they may
experience on a regular basis. Part of this response centers around (1) ROS as damaging …

Tapetal death is essential for the provision of many molecules required for pollen
development including nutrients, proteins, lipids and polysaccharides. The molecules …

Nicotianamine (NA), a chelator of metals, is ubiquitously present in higher plants.
Nicotianamine aminotransferase (NAAT) catalyzes the amino group transfer of NA in the …

In flowering plants, male fertility depends on proper cell differentiation in the anther.
However, relatively little is known about the genes that regulate anther cell differentiation …

In mammals, mitochondria have been shown to play a key intermediary role in apoptosis, a
morphologically distinct form of programmed cell death (PCD), for example, through the …

Cold temperatures cause pollen sterility and large reductions in grain yield in temperate rice
growing regions of the world. Induction of pollen sterility by cold involves a disruption of …

Extracellular invertase mediates phloem unloading via an apoplastic pathway. The gene
encoding isoenzyme Nin88 from tobacco was cloned and shown to be characterized by a …

The tapetum plays a critical role during the development and maturation of microspores.
DYSFUNCTIONAL TAPETUM 1 (DYT 1) is essential for early tapetal development. Here, we …

The tapetum plays a crucial role in pollen development. This secretory tissue produces
numerous nutritive proteins necessary for pollen maturation. The tapetum, whose cells …

Efforts in hybrid breeding have made this technology one of the main factors contributing to
the substantial global rise in agricultural output over the last few decades. For hybrid …
