This review focuses on physiological responses in higher plants to B deficiency at the whole
plant and organ level. Plants respond to decreasing B supply in soil solutions by slowing …

There is probably no major biochemical process in plants that is both so important and so
poorly understood at the molecular level as cellulose synthesis. This is surprising, because …

▪ Abstract The past few decades have witnessed exciting progress in studies on the
biosynthesis of cellulose. In the bacterium Acetobacter xylinum, discovery of the activator of …

Abstract Synthesis of callose (β-1, 3-glucan) in plants has been a topic of much debate over
the past several decades. Callose synthase could not be purified to homogeneity and most …

Callose is synthesized on the forming cell plate and several other locations in the plant. We
cloned an Arabidopsis cDNA encoding a callose synthase (CalS1) catalytic subunit. The …

Cellulose occurs in all higher plants and some algae, fungi, bacteria, and animals. It forms
microfibrils containing the crystalline allomorphs, cellulose Iα and Iβ. Cellulose molecules …

ABSTRACT The mixed‐linkage (1→ 3),(1→ 4)‐β‐d‐glucans are unique to the Poales, the
taxonomic order that includes the cereal grasses.(1→ 3),(1→ 4)‐β‐Glucans are the principal …

The distribution of cellulose and callose in the walls of pollen tubes and grains of Nicotiana
tabacum L. was examined by electron microscopy using gold-labelled cellobiohydrolase for …

In lily, adhesion of the pollen tube to the transmitting-tract epidermal cells (TTEs) is
purported to facilitate the effective movement of the tube cell to the ovary. In this study, we …

The walls deposited by growing pollen tubes contain two types of β-glucan, the (1, 3)-β-
glucan callose and the (1, 4)-β-glucan cellulose, as well as various α-linked pectic …
