Isoetes ×atruensis (Isoetaceae – Lycopodiopsida), a new interspecific sterile hybrid from Rajasthan of Western India

open access: yesNordic Journal of Botany, EarlyView.
Isoetes ×atruensis hyb. nov. is shown to be a triploid (2n = 3× = 33 + 1) sterile interspecific hybrid between diploid (2n = 2× = 22 + 1) I. coromandelina and tetraploid (2n = 4× = 44 + 1) I. rajasthanensis. It has been found in two locations in Rajasthan, India.

Wheat breeding approaches for designing wheat to thrive in a warmer world

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
Wheat is a vital food crop, accounting for approximately 20% of daily calories and protein consumed worldwide. However, modern‐day wheat is under pressure from global change. The improvement rate of wheat yields is not keeping up with the demand of our growing population. Furthermore, abiotic and biotic stressors are becoming more prevalent. This paper

Flower Forms and Ploidy Levels Impact Fertility in Althea

open access: yesHortScience, 2022
Althea (Hibiscus syriacus) is a popular shrub known for its vibrant summer blooms and winterhardiness; however, althea produces capsules with numerous seeds that germinate and cause a nuisance in production and the home landscape.

Engineering compact Physalis peruviana (goldenberry) to promote its potential as a global crop

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
Goldenberry (Physalis peruviana) produces sweet, nutritionally rich berries, yet like many minor crops, is cultivated in limited geographical regions and has not been a focus of breeding programs for trait enhancement. Leveraging knowledge of plant architecture‐related traits from related species, we used CRISPR/Cas9‐mediated gene editing to generate a

TETRAPLOID FEMALES IN MORMONIELLA

open access: yesGenetics, 1969
IN the wild-type hymenopteron, Mormoniella, it has been shown that five atelomitic chromosomes are characteristic of the male and that unlaid eggs have five bivalents, indicating that normal diploid females have ten chromosomes (WHITING 1968). In the polyploid stocks, the diploid males, identified by complementary allelism, have ten chromosomes ...

Past, present and future of local crop evolution

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
Promoting agrobiodiversity is a promising strategy for mitigating the negative effects of climate change on global food security. We highlight the central role evolutionary processes play in harnessing the potential of local crops by integrating genomics, archaeology, ethnobotany and traditional ecological knowledge (TEK).

UTILIZING DISCRETE HIDDEN MARKOV MODELS TO ANALYZE TETRAPLOID PLANT BREEDING

open access: yesJurnal Matematika UNAND
In plant heredity, the phenotype is the result of observation that can be directly observed, while the genotype is the underlying hidden factor that underlies the expression of the phenotype.

Gene turnover in the common ancestor of all C4 grasses

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
Understanding how plants evolve more efficient photosynthesis is important in a warming world where improving crop productivity and resilience is a global priority. By generating the first reference genomes for an early‐diverging group of grasses called the Aristidoideae, we were able to reconstruct the genetic makeup of the last common ancestor of all

In vivo polyploidy induction of Phalaenopsis amabilis in a bubble bioreactor system using colchicine

open access: yesOrnamental Horticulture, 2021
Phalaenopsis amabilis Blume var. grandiflora Bateman is economically important as cut and pot flower. Polyploidy is considered as a valuable tool in improvement and evolution of ornamental plants. Protocorm-like bodies (PLBs) of P. amabilis were cultured
