“…In this study, the diploid chromosome count of 2n = 44 and haploid chromosome count of n = 22 indicates a basic chromosome number of x = 11 thereby indicating a chromosome number of 2n = 4x = 44 for the green-stemmed and the red-stemmed Basella alba studied. This is in line with the reports of Silva et al (2017) for Basella alba species obtained from Brazil. The chromosome numbers obtained for the green-stemmed and red-stemmed Basella alba in this study contradicts those of Hanson et al (2005) who reported chromosome numbers 2n = 48, 41 and 44 for those obtained from England.…”

“…It also contradicts the reports of Sperling and Bittrich (1993) who reported the basic chromosome number of x = 12 for B. alba. According to Silva et al (2017) the chromosome number 2n = 44 observed in B. alba may have been derived from descending disploidy from the number 2n = 4x = 48.…”

“…Previous cytological studies on the genus Basella indicated varying reports on the chromosome numbers of the green-stemmed and the red-stemmed B. alba., with the reports varying from chromosome numbers 2n = 44 to 2n = 45 and 2n = 48 (Hanson et al, 2005;Silva et al, 2017). There is no known report of chromosome numbers of B. alba morphotypes from Nigeria.…”

“…Chromosomes are key building blocks of eukaryotic genomes (Tiang et al, 2012) and the cytogenetic characterisation of species require in-depth studies of the chromosome numbers and chromosomal behaviours of the species and their morphogenic varieties (Silva et al, 2017). Meiosis, a process by which sexually reproducing organisms reduce their genome from diploid to haploid (John, 1990) is a highly coherent and genetically controlled process (Pessim et al, 2015) which involves the process of commitment and initiation, homologous chromosome pairing, synapsis, inter-homologous reciprocal recombination, disjunctive segregation and haploid gamete formation (Murphy and Bass, 2012).…”

Morphological characterization and cytological studies of the green-stemmed and the red-stemmed Basella alba

Basella alba is an underutilized vegetable with ethnobotanical importance used for culinary as well as medicinal purposes in many parts of the world. Morphological characterization and chromosome studies of the mitotic and meiotic cells of the green stemmed and the red-stemmed B. alba was carried out with a view to filling the knowledge gaps that exist in their morphological characterization and also to provide insightful information on their chromosome numbers and meiotic behaviour. The B. alba accessions studied were characterized with respect to their habit, leaves, inflorescence, fruits and seeds. Mitotic and meiotic studies were carried out on the Basella accessions using standard techniques. The morphological studies revealed significant differences between the green-stemmed and red-stemmed Basella alba with respect to the green/red colour of their stems, colour of the flower bud apex, mean plant height at flower bud initiation, mean leaf length, mean leaf width, mean petiole length, mean flower per spike, mean fruit length and mean fruit diameter. The cytological study revealed a chromosome number of 2n=4x=44 for both the green-stemmed and the red-stemmed B. alba studied. It also revealed the occurrence of chromosomal aberrations such as stickiness and precocious migration of chromosomes to the poles during meiosis, which could lead to irregular chromosome segregation that could result in chromosome instability and aberrant meiotic products within the species.

Plantas Alimentícias Não Convencionais (PANC) consiste em vegetais, ou partes de vegetais cujoconsumo não é comum para uma determinada região. Estas plantas comumente recebem adenominação de plantas daninhas, invasoras ou matos. O Brasil é rico em biodiversidade vegetal,mas apenas uma baixa porcentagem das plantas são consumidas na alimentação humana. Oobjetivo deste estudo é identificar as PANC que podem ser utilizadas na alimentação e orientara comunidade sobre modo de preparo e consumo. A metodologia consistiu em pesquisa exploratória para a identificação das PANC, através de conversas com pessoas idosas e aplicação deum questionário em um evento sobre PANC que ocorreu na UNESPAR no ano de 2022.As PANCidentificadas foram alvo de pesquisa bibliográfica que resultou em um catálogo sobre PANC.Osresultados demonstram que houve redução no consumo de plantas alimentícias não convencionais e que as plantas mais utilizadas foram ora-pro-nobis com 12,5% , serralha, com 5% , almeirãoroxo, peixinho da horta e taioba, ambas com 3,1% das respostas entre 33,8% das pessoas queafirmaram já ter consumido alguma PANC. Em contrapartida, 66,2% das pessoas, disseram nuncater consumido e não conhecer nenhuma PANC. Estes resultados mostram que é importante oresgate da utilização de PANC visando a diversidade alimentar.
