Two Indel Variations in the Regulated Carotenoid Pigment Gene Hold the Key to the Interspecies Flower Colour Differentiation in Liriodendron Plants

open access: yesPlant Biotechnology Journal, Volume 24, Issue 4, Page 2260-2275, April 2026.
ABSTRACT Flower colour variation is pivotal for plant evolution, ecological adaptation, and pollinator attraction. In the Liriodendron genus, L. tulipifera features a distinct orange petal stripe which is absent in L. chinense, driven by differential carotenoid accumulation, yet the underlying genetic mechanism remains unclear.

Automation of pollen analysis using a computer microscope : a thesis presented in partial fulfilment of the requirements for the degree of Master of Engineering in Computer Systems Engineering at Massey University [PDF]

open access: yes, 2004
The classification and counting of pollen is an important tool in the understanding of processes in agriculture, forestry, medicine and ecology. Current pollen analysis methods are manual, require expert operators, and are time consuming.

Was the evolution of faster stomata driven by increased gas exchange rates rather than increasing water use efficiency?

open access: yesNew Phytologist, Volume 249, Issue 5, Page 2355-2371, March 2026.
Summary Following changes in light flux, photosynthesis (A) typically adjusts more quickly than stomatal conductance (gs), which is dependent on changes in stomatal aperture. Faster stomatal responses are proposed to reduce water loss and enhance growth in dynamic light environments. Stomatal opening and closing parameters were determined in a range of

Measurement of Ungulate Palatability and Browsing Pressure on Japanese Flora

open access: yesEcological Research, Volume 41, Issue 1, January 2026.
Estimation of palatability and browsing pressure are key techniques for ecosystem management. We compared four methods to estimate palatability based on browsing scar survey and proposed the reference palatability values for the Japanese flora as plant ecological trait.
