New species and new combinations in Sonerila and Phyllagathis (Melastomataceae) from Thailand [PDF]

, 1997
While revising the Melastomataceae for the Flora of Thailand, we discovered two new species of Sonerila, as well as the need for transferring two species of Tylanthera endemic to Thailand into Phyllagathis. Sonerila urceolata and S. loeiensis are endemic

Early evolutionary history of the seed

Biological Reviews, EarlyView.
ABSTRACT The seed is an essential stage in the life history of gymnospermous and angiospermous plants, facilitating both their survival and dispersal. We reappraise knowledge of the evolutionary history of the gymnospermous seed, from its origin in the late Devonian through to the well‐known end‐Permian extinctions – an interval encompassing the ...

PEK14: A Kinesin‐4 Necessary for Male‐Derived Fertility in Arabidopsis thaliana

Cytoskeleton, EarlyView.
ABSTRACT Of the 61 kinesins annotated in Arabidopsis thaliana, many are still without assigned function. Here, we have screened an insertional mutant library of Arabidopsis pollen‐expressed kinesins for fertility defects. Insertional mutants for three kinesins showed a significant reduction in seed set.

Borax Promotes Fertility of Brassica napus Better Than Other Boron Species at Suboptimal Supply

Journal of Plant Nutrition and Soil Science, EarlyView.
ABSTRACT Background Continuous and sufficient boron (B) supply is essential for achieving maximum yield in Brassica napus. Increasing incidences of environmental water limitation are linked to reduced plant B availability and increased B deficiencies.

The effect of different processing methods on nutrient retention in African leafy vegetables (fig‐leaf gourd leaves)

JSFA reports, EarlyView.
Abstract Background Inadequate nutrition is a leading factor in global health challenges, particularly in sub‐Saharan Africa, where malnutrition and hunger remain widespread. Fig‐leaf gourd (Cucurbita ficifolia), a nutrient‐dense African leafy vegetable, is readily available to low‐income populations and holds promise for improving micronutrient intake

Risk Factors Associated With the Number of Symptoms and Distress Caused by Genitourinary Syndrome of Menopause in Taiwanese Women

The Kaohsiung Journal of Medical Sciences, EarlyView.
ABSTRACT A high percentage of women who undergo the transition to postmenopause experience both menopausal symptoms and genitourinary syndrome of menopause (GSM). However, GSM is often underdiagnosed. This research aims to identify risk factors that may influence the number of GSM symptoms and whether they cause distress in Taiwanese women > 45 years ...
