Conifer cell cultures as a tool for studying the induction of terpenoid defense compounds Bot. Lett. (IF 1.5) Pub Date : 2023-07-21 Gazmend Zeneli, Trevor M. Fenning, Jonathan Gershenzon
ABSTRACT Conifer trees often increase their production of terpene resins after attack by herbivores or pathogens, a defense response that may be critical in their survival. Yet it has proved difficult to study such terpene induction under laboratory conditions because of the need for mature trees and specific organs and cells at the proper stage of development. Here we explore the potential of Norway

A malformation of sex-changing plant Arisaema serratum (Araceae) produces both male and female inflorescences Bot. Lett. (IF 1.5) Pub Date : 2023-07-13 Tetsuya K. Matsumoto, Ryohei Fujisato, Munetaka Sugiyama, Yuko Miyazaki, Jin Murata
ABSTRACT The genus Arisaema (Araceae) can change sex expression between male and female with increasing plant size (sequential hermaphrodism). As most Arisaema species have only one inflorescence on each individual, sex expression is seemingly determined at the individual level. However, malformations with male and female inflorescences have occasionally been observed. Unfortunately, their developmental

Stomatal shape described by a superellipse in four Magnoliaceae species Bot. Lett. (IF 1.5) Pub Date : 2023-07-12 Qiying Li, Karl J. Niklas, Ülo Niinemets, Liuyue Zhang, Kexin Yu, Johan Gielis, Jie Gao, Peijian Shi
ABSTRACT Stomata are essential for the exchange of water vapour and atmospheric gases between vascular plants and their external environments. The stomatal geometries of many plants appear to be elliptical. However, prior studies have not tested whether this is a mathematical reality, particularly since many natural shapes that appear to be ellipses are superellipses with greater or smaller edge curvature

Estimation of stomatal density of leaves with hierarchical reticulate venation Bot. Lett. (IF 1.5) Pub Date : 2022-12-21 Peijian Shi, Lin Wang, Ülo Niinemets, Yabing Jiao, Karl J. Niklas
ABSTRACT Stomatal density (SD) is important to photosynthetic rates. However, it is time-consuming to measure SD. Here, we provide a method for estimating SD based on the scaling relationship between SD and mean nearest neighbour distance (MNND) of sampled stomatal centres. 397 leaves from eight Magnoliaceae species were used for this study. For each leaf, three 1.2 mm × 0.9 mm lamina sections, positioned
