The Zygnematales (Greek: ζυγός (zygós) and νῆμα (nḗma) (nom.), νήματος (nḗmatos) (gen.)), also called the Conjugatales, [1] are an order of green algae, [2] comprising several thousand different species in two families.

Feb 19, 2020 · We present data on the life cycle of the genera Micrasterias and Spirogyra, representing the orders Desmidiales and Zygnematales, and outline the current status of genetic transformation of Zygnematophyceae algae and future research perspectives.

The Zygnematales also called the Conjugales, are an order of green algae, comprising several thousand different species in genera such as the well-known Zygnema and Spirogyra. All the members of this group develop into unbranched filaments, one cell thick, which grow longer through normal cell division.

Zygnematophyceae (or Conjugatophyceae) is a class of green algae in the paraphylum streptophyte algae, also referred to as Charophyta, [2] consisting of more than 4000 described species. [3] . The Zygnematophyceae are the sister clade of …

The order Zygnematales is distinguished from the order Desmidiales, because it lacks segmentation of the cell wall into two or more pieces and the specialized cell wall pores that characterize the latter order. Filamentous Zygnematales have cylindrical cells.

The meaning of ZYGNEMATALES is an order of green algae (class Chlorophyceae) that include the pond scums and desmids, are distinguished by the absence of asexual reproduction and lack of flagellated reproductive structure, and reproduce sexually by fusion of amoeboid gametes.

The Zygnematales (Greek: ζυγός (zygós) and νῆμα (nḗma) (nom.), νήματος (nḗmatos) (gen.)), also called the Conjugatales, are an order of green algae, comprising several thousand different species in two families.

Conjugating green algae (class Zygnematophyceae) are the most species-rich group of charophyte algae, with more than 4000 described species (Gerrath, 2003). They are morphologically diverse and visually attractive.

The earliest use of the name Zygnematales appears to be by the American phycologist Charles Edwin Bessey (1845-1915), and it was he who first formally redistrib-uted all conjugating algae from the ‘Conjugatae’ to the orders Zygnematales and the Desmidiales.

It is one of the common green algae occurring chiefly in ponds, pools, ditches, and similar other places. It prefers still, rather than running water and is one of the free-floating algae known as ‘pond scum’.
