“…Кроме того, селекционеры могут оценивать линии удвоенных гаплоидов (DH-линии) с большей скоростью, точностью и достоверностью, поскольку все гены у DH-растений находятся в гомозиготном состоянии, и рецессивные признаки видны, а не маскируются под действием доминантных генов. Гаплоидные и удвоенные гаплоидные растения также удобно использовать в генетических и фундаментальных исследованиях (Dong et al, 2016;Can et al, 2019). Например, Lofti и др.…”

“…Современное состояние исследований по получению удвоенных гаплоидов огурца. Основные достижения по получению удвоенных гаплоидов у огурца за послед-ние 30 лет были освещены в ряде обзоров (Przyborowski, 1996; Gałązka, Niemirowicz-Szczytt 2013; Dong et al, 2016). В настоящее время гаплоидные и удвоенные гаплоидные растения в семействе Cucurbitaceae получают при использовании: 1. партеногенеза in situ (опыление неполноценной (облученная или обработанная химическими веществами) пыльцой); 2. андрогенеза (культуры пыльников/микроспор in vitro); 3. гиногенеза (культура неопыленных семяпочек in vitro).…”

“…При культивировании на искусственных питательных средах гаплоидные клетки зародышевого мешка переходят с гаметофитного пути развития на спорофитный с образованием из них эмбриоидов (прямой эмбриогенез) или морфогенного каллуса, из которого в последующем образуется растение (непрямой эмбриогенез). Chambonnet D. и Dumas de Vaulx R. (1985) впервые получили в культуре неоплодотворенных семяпочек in vitro гаплоидные растения кабачка, и с этого времени гиногенез является альтернативным источником получения удвоенных гаплоидов у овощных культур семейства Cucurbitaceae (Dong et al, 2016). На процесс индукции гиногенеза влияет большое число факторов: генотип растения, условия выращивания донорного растения, стадия развития женского гаметофита, состав питательной среды, стрессовые обработки.…”

“…Dong et al, 2016). Дозы облучения не должны быть такими высокими, чтобы полностью ингибировать прорастание пыльцевых трубок, но в тоже время они должны быть достаточно высокими, чтобы нарушать нормальное оплодотворение и препятствовать образованию диплоидных гибридных эмбриоидов.…”

Production of Doubled Haploids in cucumber

Implementation of cell technologies has essentially improved the plant breeding process in agricultural crops in the world. The production of pure lines in cultivated crops, particularly among cross-pollinated species such as cucumber (Cucumis sativus L.) requires much time, labor and expense. Thus, the use of DH-plants for production of fully homozygous lines for one year becomes a very promising method for near cucumber breeding program. The major factor limiting the wide use of DH is a lack of effective protocol for large-scale plant production. In this review the historical facts with description of three main methods of DH-plant production were presented. By now these three methods have been such as parthenogenesis in situ induced by pollination with irradiated or chemically treated pollen; androgenesis in vitro including anther and isolated microspore cultivation in vitro; gynogenesis through ovule cultivation in vitro. Comparative analysis of published data with regard to the efficiency of the technology for DH-plant production was shown as well as advantages and limitations of each technology were described.

“…In addition, gynogenesis has usually a low efficiency. Currently, gynogenesis is the method of choice for breeding species of the genera Allium and Beta, but a number of other species are responsive, such as barley, wheat, maize, mulberry, coconut, saffron and different Cucurbitaceae Dong et al 2016).…”

Thesis layout and cover design: Alba Rivas Sendra and André Arôxa Watercolor drawings: Alba Rivas Sendra AcknowledgementsEn primer lugar, quiero dar las gracias especialmente a Jose María, que me ha guiado en este proceso desde el primer momento. Me ha impulsado a crecer y, cuando no era posible, me ha traído un banquito para que pudiera alcanzar siempre más alto. Con tu ayuda me he convertido en una investigadora y todo lo que he aprendido me acompañará para siempre. Aunque a veces ponernos de acuerdo ha sido un reto, eso representa la esencia misma de la investigación y la ciencia, y lo agradezco sinceramente. Los retos siempre nos inspiran, nos obligan a aprender, a mantenernos activos y a tener menos miedo de las soluciones creativas. Y de esto es mejor tener los bolsillos llenos.También quiero expresar mi sincero agradecimiento a Kim Boutilier. Ella me abrió sus puertas el primer día, y las mantiene abiertas desde entonces. No solo aprendí cosas nuevas de los mejores expertos, sino que la estancia en su laboratorio me permitió ver un mundo diferente, encontrar un segundo hogar, sembrar y recoger muchísimo amor expatriado increíblemente verdadero, y darme cuenta de que son las cosas más diminutas (como puede ser una pequeña bici rosa) las que llenan nuestras vidas de felicidad.Familia, amigos, amigos que se convierten en familia, todos habéis tenido un papel en la parte de mí que queda reflejada en este libro. Los que siempre habéis caminado a mi lado, los que aparecisteis un día y ya nunca os marchasteis, los que acabáis de llegar pero es como si siempre hubieseis estado aquí, los que me dais la bienvenida cuando vuelvo a casa, donde quiera que mi casa esté, e incluso aquellos que solo me acompañaron durante una etapa... Todos vosotros habéis ayudado a dar forma a la persona que soy hoy. No hay un momento del que me arrepienta, un beso que desee nunca haber dado, una palabra que preferiría no haber oído. Ha sido un largo camino, pero esto es solo el comienzo. Las olas siguen llegando a la playa, las células siguen creciendo en nuestras placas de cultivo, y la vida, como el espectáculo, debe continuar. Lo único importante es ser feliz. Siempre hacia delante y apuntando alto, retroceder nunca, rendirse jamás (Corey Yuen, 1986).First of all, I specially want to thank Jose María, who has guided me through this life-changing process since the very beginning. He encouraged me to grow, and when it was not possible, he brought me a stool so I could always reach higher.With your help I became a researcher, and everything I learnt will be with me forever. Even though sometimes it was challenging to come to an agreement, this represents the core essence of research and science, and I truly appreciate it.Challenges always inspire us, make us learn, keep us active and take away our fear of creative solutions. And it is always better to have plenty of these.I also want to express my sincere thanks to Kim Boutilier. She opened her door to me on the first day, and still holds it open. Not only have I learnt new things from...

Apart from Li4Ti5O12, there are few anode substitutes that can be used in commercial high‐power lithium‐ion batteries. Orthorhombic T‐Nb2O5 has recently been proven to be another substitute anode. However, monoclinic B‐Nb2O5 of same chemistry is essentially inert for lithium storage, but the underlying reasons are unclear. In order to activate the “inert” B‐Nb2O5, herein, nanoporous pseudocrystals to achieve a larger specific capacity of 243 mAh g−1 than Li4Ti5O12 (theoretical capacity: 175 mAh g−1) are proposed. These pseudocrystals are rationally synthesized via a “shape‐keep” topological microcorrosion process from LiNbO3 precursor. Compared to pristine B‐Nb2O5, experimental investigations reveal that B‐Nb2O5−x delivers ≈3000 times higher electronic conductivity and tenfold enhanced Li+ diffusion coefficient. An ≈30% reduction of energy barrier for Li‐ion migration is also confirmed by the theoretical calculations. The nanoporous B‐Nb2O5−x delivers unique ion/electron transport channels to proliferate the reversible and deeper lithiation, which activate the “inert” B‐Nb2O5. The capacitive‐like behavior is observed to endow B‐Nb2O5−x ultrafast lithium storage ability, harvesting 136 mAh g−1 at 100 C and 72 mAh g−1 even at 250 C, superior to Li4Ti5O12. Pouch‐type full cells exhibit the energy density of ≈251 Wh kg−1 and ultrahigh power density up to ≈35 kW kg−1.
