BcMF9, a novel polygalacturonase gene, is required for both Brassica campestris intine and exine formation.
BACKGROUND AND AIMS The polygalacturonase (PG) gene family has been found to be enriched in pollen of several species; however, little is currently known about the function of the PG gene in pollen development. To investigate the exact role that the PG gene has played in pollen development and about this family in general, one putative PG gene, Brassica campestris Male Fertility 9 (BcMF9), was ...
متن کاملThe polygalacturonase gene BcMF2 from Brassica campestris is associated with intine development
Brassica campestris Male Fertility 2 (BcMF2) is a putative polygalacturonase (PG) gene previously isolated from the flower bud of Chinese cabbage (Brassica campestris L. ssp. chinensis Makino, syn. B. rapa ssp. chinensis). This gene was found to be expressed specifically in tapetum and pollen after the tetrad stage of anther development. Antisense RNA technology was used to study the function o...
متن کاملPollen-wall proteins: quantitative cytochemistry of the origins of intine and exine enzymes in Brassica oleracea.
Simultaneous coupling methods for detection of acid phosphatase and non-specific esterase produce a coloured reaction product that is quantitatively related to enzyme content in freeze-sectioned Brassica pollen and tapetal cells. The intine-located acid phosphatase has 2 periods of synthesis: the first in late vacuolate period, associated with the completion of deposition of the intine polysacc...
متن کاملDEX1, a novel plant protein, is required for exine pattern formation during pollen development in Arabidopsis.
To identify factors that are required for proper pollen wall formation, we have characterized the T-DNA-tagged, dex1 mutation of Arabidopsis, which results in defective pollen wall pattern formation. This study reports the isolation and molecular characterization of DEX1 and morphological and ultrastructural analyses of dex1 plants. DEX1 encodes a novel plant protein that is predicted to be mem...
متن کاملSequence of a Brassica campestris myrosinase gene.
Myrosinase (thioglucoside glucohydrolase, P-thioglucosidase, EC 3.2.3.1) catalyzes the hydrolysis of glucosinolates, a diverse group of sulfur-containing glycosides that are present in a11 the Cruciferae, to D-G~c, sulfur, and a variety of volatile compounds including thiocyanates, isothiocyanates, and nitriles (Fenwick et al., 1983). Normally, myrosinase and the glucosinolates are kept sequest...
