Tree Composition and Seedling Recruitment in Urban and Rural Forests [PDF]

open access: yes, 2015
In 1993, Dr. Nancy Broshot randomly located 25 permanent study sites in Forest Park in Portland, Oregon to examine the effects of urbanization on forest health. Plant community structure was examined. In 2003, Dr. Broshot reexamined the plant communities

PRC1‐Mediated H2Aub Loop Formation and Function in Arabidopsis

open access: yesAdvanced Science, EarlyView.
In the Arabidopsis genome, H2Aub and H3K27me3 marks do not always co‐localize, and some regions are marked exclusively by H2Aub. By using Capture‐Hi‐C, it is found that H2Aub loops are preferentially established between two H2Aub enriched regions.

Co‐Selection of Low Cadmium Accumulation and High Yield During Tomato Improvement

open access: yesAdvanced Science, EarlyView.
This study finds that large‐fruited tomatoes accumulate less cadmium (Cd) compared to wild tomatoes and cherry tomatoes. This is because, during the improvement process of tomato, the low‐Cd allele LCT1A and the large fruit allele fw3.2T are closely linked, leading to a co‐selection event.

Tetraploidisation is a common phenomenon in apomictic Citrus seedlings affected by genotype and environmental conditions [PDF]

open access: yes, 2009
Citrus species are mainly diploid (2n=2x=18) and very few natural polyploid are encountered in the citrus gene pool. However, several reports of tetraploid seedlings occurrence from apomictic citrus have been done during the last century.

Ethylene-independent promotion of photomorphogenesis in the dark by cytokinin requires COP1 and the CDD complex [PDF]

open access: yes, 2019
The transition of skotomorphogenesis to photomorphogenesis is induced by the perception of light, and is characterized by the inhibition of hypocotyl elongation and opening of cotyledons.

GmSop20 Functions as a Key Coordinator of the Oil‐To‐Protein Ratio in Soybean Seeds

open access: yesAdvanced Science, EarlyView.
This study investigates the seed oil‐to‐protein ratio as a comprehensive quality metric and identifies GmSop20 as a crucial regulatory gene through forward genetics methodologies. By integrating GmSop20 with superior haplotypes and using gene editing/overexpression, new strategies are provided for precisely tuning the seed oil‐to‐protein ratio, thereby

Physiological and molecular responses of diploid and tetraploid Carrizo Citrange under water Stress : S02P14 [PDF]

open access: yes, 2013
In citrus, the use rootstock promotes productivity, improves fruit quality and may confer resistance or tolerance to biotic and abiotic stress. 'Carrizo' citrange (Citrus sinensis [L.] Osbeck × Poncirus trifoliata [L.] Raf), is one of the most popular ...

A fast ethanol assay to detect seed deterioration [PDF]

open access: yes, 2012
The most common way to test seed quality is to use a simple and reliable but time- and space-consuming germination test. In this paper we present a fast and simple method to analyse cabbage seed deterioration by measuring ethanol production from ...
