The present study insights into the interrelationships and taxonomic segregation of some Polypodiaceous fern taxa based on leaf architecture foliar micro-morphology. Twenty-seven species were examined valuable qualitative quantitative data obtained to generate UPGMA dendrogram. A dichotomous key differentiating was prepared. Results reveal that even though have overlapping characters, certain s...

Abstract. Arumingtyas EL, Atiaturrochmah, Kusnadi J. 2023. Confirmation of mutation and genetic stability the M4 generation chili pepper’s (Capsicum frutescens L.) Ethyl Methane Sulfonate (EMS) mutant based on morphological, physiological molecular characters. Biodiversitas 24: 531-538. The initial random mutations usually still shows high variation due to allele segregation. This research aime...

Abstract The information on genetic parameters need to be known in relation the selection process for breeding of high yielding plant genotypes. This study aims estimate frequency distribution, segregation pattern, and transgressive agronomic characters M3 generation red chili “Laris” variety after gamma-ray irradiation. research was conducted at Integrated Field Laboratory, Faculty Agriculture...

Two accessions, representing the species Lycopersicon esculentum (cultivated tomato) and Lycopersicon pennellii (a wild relative), were evaluated for 11 quantitative traits and found to be significantly different for 10 of the traits. Transgressive segregation was observed for eight of the traits in a large interspecific F2 population. When restriction fragment length polymorphism markers were ...

eleven populations of five avena species were analysed for meiotic characters including chiasma frequency and distribution as well as chromosomal association and segregation. plants of a single population of a. eriantha showed the presence of 2n = 14 (diploid) and 2n = 4x = 28 chromosome number. populations of a. barbata and a. wiestii possessed n = 14, while populations of a. sterilis ssp. lud...

BACKGROUND How do we estimate time when watching an action? The idea that events are timed by a centralized clock has recently been called into question in favour of distributed, specialized mechanisms. Here we provide evidence for a critical specialization: animate and inanimate events are separately timed by humans. METHODOLOGY/PRINCIPAL FINDINGS In different experiments, observers were ask...

Mendel's paper 'Versuche über Pflanzen-Hybriden' is the best known in a series of studies published in the late 18th and 19th centuries that built our understanding of the mechanism of inheritance. Mendel investigated the segregation of seven gene characters of pea (Pisum sativum), of which four have been identified. Here, we review what is known about the molecular nature of these genes, which...

This study provides the most detailed description of the immature stages of Agrilus planipennis Fairmaire to date and illustrates suites of larval characters useful in distinguishing among Agrilus Curtis species and instars. Immature stages of eight species of Agrilus were examined and imaged using light and scanning electron microscopy. For A. planipennis all preimaginal stages (egg, instars I...
