haploid cell:

see meiosismeiosis
, process of nuclear division in a living cell by which the number of chromosomes is reduced to half the original number. Meiosis occurs only in the process of gametogenesis, i.e., when the gametes, or sex cells (ovum and sperm), are being formed.

Notably, these haploid cell screens identified six members of the HOPS complex, proteins known to play functions in endosomal/lysosomal trafficking, as well as the Niemann-Pick C1 (NPC1) transporter as the most prominent hit of the assay.
Additionally, Horizon offers rapid and low cost on-demand generation of engineered haploid cell lines that for the first time bring these valuable research tools to the 72,000+ research labs studying the basic and applied function of genes and genetic variation.

Five aquaporins, Aqp1ab, -7, and -10b, are expressed in all germ cells, from spermatogonia to luminal spermatozoa, whereas Aqp1aa and -8b are only found in haploid cells (Table 1).

The first nuclear division of meiosis (meiosis I) is accompanied with the formation of two haploid cells in a dyad form (Fig1 M& N).
These haploid cells show all of the same characteristics as stem cells with two sets of chromosomes, and retain the same full developmental potential, making them a powerful tool for determining how the genetic circuitry of mammalian development functions.
The advantages of using a late-unicellular or bicellular microspores are that (1) microspores are single haploid cells and highly synchronous in development (Aionesei et al.,2006), and (2) the probability of incorporation of introduced DNA into the generative genome is increased (Aziz and Machray, 2003).
Before infection can occur, the smuts need to undergo a successful mating to form dikaryotic hyphae (two haploid cells fuse to form a dikaryon).
It occurs in specialized cells (sporocytes) of the sporophyte (spore producing) generation and yields haploid cells that initiate the gametophyte (gamete-producing) generation.
Many growers rely on asexual truffle propagation, in which two haploid cells from a single fungus - each with one copy of the genome - fuse to form the diploid fruiting body (the truffle), which has two copies.
