Chromosome doubling can increase heat tolerance in Lonicera japonica as indicated by chlorophyll fluorescence imaging

open access: yesBiologia Plantarum, 2011
Imaging fluorometry was applied to investigate the tolerance of Japanese honeysuckle (Lonicera japonica Thunb.) of different ploidy levels to heat stress. Seedlings of L. japonica, the diploid cv. Damaohua and the tetraploid cv.

Case Report: Tetraploid Leukemia [PDF]

open access: yesBlood, 1971
Abstract A patient with acute leukemia and tetraploid blast cells in the bone marrow is reported. The patient was a 69-yr-old white male who was referred to our institution for chemotherapy. His bone marrow contained 89% blasts, 30% of which were peroxidase positive. The clinical history was characterized by a rapid, downhill course, and

Induction and characterization of tetraploid pear from the seeds of 'Dangshansuli' (Pyrus bretschneideri Rehd.)

open access: yesFruit Research, 2023
Pear is one of the most economically important fruit crops widely distributed around the world. To enrich the pear germplasm resources for obtaining the polyploid plants, the seeds from pear cultivar of 'Dangshansuli' (Pyrus bretschneideri) were treated ...

Introgressed Variation in TaMYB7‐A1 Drives Graded Dormancy and Climate‐Adaptive Pre‐Harvest Sprouting Resistance in Wheat

open access: yesAdvanced Science, EarlyView.
TaMYB7‐A1 directly activates TaABI5 to enhance ABA signaling and regulate ABA‐GA homeostasis, enforcing seed dormancy. Its superior allele, derived from wild einkorn introgression, harbors a MITE insertion that elevates expression and two amino acid substitutions that enhance transcriptional activity, collectively generating graded PHS resistance for ...

Breeding polyploid Populus: progress and perspective

open access: yesForestry Research, 2022
Populus is a genus of 25−30 species of deciduous flowering plants in the family Salicaceae, which are primarily planted in short-rotation planations for producing timber, pulpwood, wooden products as well as bioenergy feedstock; they are also widely ...

Placental Site Trophoblastic Tumor Acquires Immune Functions by Incorporating Host Maternal Genes

open access: yesAdvanced Science, EarlyView.
PSTT cells, through cell fusion with B cells, incorporate abundant non‐inherited maternal genes that are detectable by DNIMA. These hybrid cells acquire immunotherapy‐resistant genetic changes and increase the expression of B cell‐derived immune‐related molecules such as Ig, HLA, LILRB, SIGLEC10, and so on, creating an immunotolerant environment around

Dielectric Elastomer Actuators as Safe and Effective Tools for Mechanostimulation of Human Cells

open access: yesAdvanced Intelligent Systems, EarlyView.
Replicating physiological forces is crucial for realistic cell models. Dielectric elastomer actuators (DEAs) offer a soft alternative, though their high voltages raised toxicity concerns. We demonstrate that DEA stimulation causes no cell damage, cell death or cell‐cycle disruption, while activating mechanosensitive responses.

Anforderungen an die Rotkleezüchtung aus pflanzen­baulicher und tierernährerischer Sicht und deren züchterische Umsetzung

open access: yesJournal für Kulturpflanzen, 2009
Rotklee ist eine bedeutende Futterpflanze, die proteinreiches Grundfutter liefert und besonders im Ökolandbau unverzichtbar ist. Neue Anforderungen an die Züchtung sind das Auftreten des Stängelbrenners, die Erhöhung der Futterqualität durch sekundäre ...
