Air investigation of some alternative methods to agrobacterium and protoplast transformation for introducing exogenous genes into plants, based on the use of pollen as a vector [PDF]
, 1987 Some of the problems involved in the search for alternative plant transformation vectors have been examined. In particular the use of pregerminated pollen as a direct transformation vector has been investigated.

Pollen grain of barley (Hordeum vulgare L.) - pattern of development
Acta Societatis Botanicorum Poloniae, 2014 Pollen development in barley follows the general pattern established for other species of Poaceae: 1) microspore division occurs at the vacuolate microspore stage with polarly located nucleus; 2) microspore mitosis is immediately followed by phragmoplast

Cell wall involvement in desiccation tolerance in the resurrection plant Craterostigma wilmsii
, 2001 Bibliography: leaves 92-129.Resurrection plants have the unique capacity to revive from an air-dried state. In order to cope with desiccation, resurrection plants have to overcome a number of stresses, mechanical stress being one.

Arabidopsis pollen extensins LRX are required for cell wall integrity during pollen tube growth [PDF]
, 2017 Proper cell wall assembly is crucial during pollen tube growth. Leucine-rich repeat extensins (LRXs) are extracellular glycoproteins which belong to the hydroxyproline-rich glycoprotein (HRGP) family.

Functional analysis of the Arabidopsis thaliana AtEP3 endochitinase
, 2001 Chitinases are enzymes that are capable of catalyzing the hydrolysis of chitin, a homopolymer of N-acetylglucosamine. Chitin is the main constituent of the exoskeleton of insects, of crustacean shells and of the cell wall of many fungi but is absent in ...

Chemically Mediated Mechanical Expansion of the Pollen Tube Cell Wall
, 2011 Morphogenesis of plant cells is tantamount to the shaping of the stiff cell wall that surrounds them. To this end, these cells integrate two concomitant processes: 1), deposition of new material into the existing wall, and 2), mechanical deformation of ...

Rice GLYCOSYLTRANSFERASE1 encodes a glycosyltransferase essential for pollen wall formation
, 2013 The pollen wall consists of an exine and an intine. The mechanism underlying its formation is not well understood. Glycosyltransferases catalyze the modification of biological molecules by attaching a single or multiple sugars and play key roles in a ...
