Plant Physiology - Arabidopsis Basic Leucine-Zipper .

ROXY1 and ROXY2 are CC-type floral glutaredoxins with redundant functions in Arabidopsis ( Arabidopsis thaliana ) anther development. We show here that plants lacking the basic leucine-zipper transcription factors TGA9 and TGA10 have defects in male gametogenesis that are strikingly similar to those in roxy1 roxy2 mutants. In tga9 tga10 mutants, adaxial and abaxial anther lobe development is ...

Anatomy of Anther | Palynology - Biology Discussion

ADVERTISEMENTS: In this article we will discuss about the anatomy of anther. 1. Anther Initiation: The dynamics of anther development and differentiation depend on the co-operative interactions between cell populations. The anther normally consists of two lobes, each with two elongated microsporangia or pollen sacs. The anther lobes are fused together by the connective tissue [.]

Characteristics of Protists | Boundless Biology

Animal-like cell membranes or plant-like cell walls envelope protist cells. In other protists, glassy silica-based shells or pellicles of interlocking protein strips encase the cells. The pellicle functions like a flexible coat of armor, preventing the protist from external damage without compromising its range of motion.
