2. What plants have (i) roots and stems but no fruits, (ii) roots, stems and fruits but no flowers, (iii) two cotyledons? 3. Is a fern a monocot or a dicot? 4. Use the key to list as much information as you about all plants that are dicots. A simple key to plants PLANTS ...
Plants with removed cotyledons showed higher diamine oxidase activity both in the shoots and in the roots when expressed per fresh weight unit. Higher diamine oxidase activity can be found also in the remaining cotyledon when one of the two cotyledons is removed (when expressed per fresh weight...
Excision of both cotyledons of Lupinus albus L. (L. termis Forssk.) seedlings at different morphological stages during the first 8 days after sowing, retarded significantly the growth of 16-day-old seedlings and decreased the content of IAA in the shoots. The effect was more obvious at the ...
Data are presented as mean ± s.e.m, and as wounded gene expression overlaps significantly with grafted gene expression during dicotyledon grafting10, comparisons were made between grafted rice versus non-grafted rice expression by two-way ANOVA. n=3. Apart from cambium-maker genes, there was ...
Low temperature (LT) is a major threat that limits growth, development, and distribution leading to plant damage and crop losses. Plants respond to cold stress through a phenomenon known as cold acclimation, which is a complex process involving changes a
Sixty-six percent of hypocotyl segments and 10.4% of cotyledon segments produced adventitious shoots, with a mean number of adventitious shoots per explant of 3.5±0.9 and 2.5±1.5, respectively. The best regeneration medium (52% shoot formation, 47% shoot elongation) for hypocotyls was MS basal...
To date, little is known about the evolution of fern genomes, with only two small genomes published from the heterosporous Salviniales. Here we assembled the genome of Alsophila spinulosa, known as the flying spider-monkey tree fern, onto 69 pseudochromosomes. The remarkable preservation of synte...

A pattern similar to that of control plants with intact cotyledons was attained when cotyledons were excised later than 8 days after sowing. It is believed that the cotyledons control the IAA content of the shoot during the early stages of development. At day 36 flower primordia were ...
radiata structure cannot be neatly correlated with previously described CI open or closed states, nor are they fully equivalent to the deactive state in mammals or yeast. Nevertheless, the presence of the π bulge in Nad6’s TMH3, which rotates hydrophobic residues into CI’s hydrophilic axis ...
